Top trading cycles (and recollections of New Orleans), in AER:Insights, by Abdulkadiroğlu, Che, Pathak, Roth and Tercieux

A decade ago I was part of the team that designed the new school choice system for the New Orleans Recovery School District.  On the District side, the effort was led by Gabriela (Gaby) Fighetti. The design team was organized by the (then) Institute for Innovation in Public School Choice (IIPSC), led by Neil Dorosin. The heavy lifting on the design was done by Atila Abdulkadiroğlu and Parag Pathak.  Until the district expanded and developed more complex requirements for expressing priorities (and we had to switch to a deferred acceptance algorithm) the design was based on a top trading cycles (TTC) mechanism. It was the first time I know of that TTC was adopted and deployed in a widely used market design. It came to be called OneApp (since it replaced the old system of applications to each school with one application followed by the matching algorithm).

Some of the data from that system make their way into this new (primarily theory) paper, about some of the distinctive virtues of top trading cycles. The paper itself is a merged effort between the New Orleans design team, and work on TTC initiated separately by various combinations of Che, Tercieux and Abdulkadiroğlu.

Efficiency, Justified Envy, and Incentives in Priority-Based Matching†

By Atila Abdulkadiroğlu, Yeon-Koo Che, Parag A. Pathak, Alvin E. Roth and Olivier Tercieux, 

American Economic Review: Insights, December, 2020, 2, (4), 425–442.

Abstract: Top Trading cycles (TTC) is Pareto efficient and strategy-proof in priority-based matching, but so are other mechanisms including serial dictatorship. We show that TTC minimizes justified envy among all Pareto-efficient and strategy-proof mechanisms in one-to-one matching. In many-to-one matching, TTC admits less justified envy than serial dictatorship in an average sense. Empirical evidence from New Orleans OneApp and Boston Public Schools shows that TTC has significantly less justified envy than serial dictatorship. 

The first footnote of the paper suggests something of it's long history, and says in part:

"This paper supersedes “The Role of Priorities in Assigning Indivisible Objects: A Characterization of Top Trading Cycles,” cited by others as Abdulkadiroglu, Atila, and ˇ Yeon-Koo Che (2010) or Abdulkadiroglu, Atila, ˇ Yeon-Koo Che, and Olivier Tercieux (2010), and “Minimizing Justified Envy in School Choice: The Design of New Orleans’ OneApp” (2017) by Abdulkadiroglu, Atila, ˇ Yeon-Koo Che, Parag A. Pathak, Alvin E. Roth, and Olivier Tercieux. Roth is a member of the scientific advisory board of the Institute for Innovation in Public School Choice (IIPSC). IIPSC was involved in designing OneApp in New Orleans. Abdulkadiroglu, Pathak, and Roth also advised Boston Public Schools and New York City’s Department of Education on designing their student assignment systems, discussed herein. This article does not represent the views of the New Orleans Recovery School District or any other school district."

And here's a paragraph that offers a different kind of historical context:

"In 2011–2012, the New Orleans Recovery School District pioneered a unified enrollment process called OneApp, integrating admissions to all types of schools under a single offer system. Officials identified three major priority groups: sibling, applying from a closing school, and geography. The discussion about mechanism centered on the trade-off between efficiency and eliminating justified envy, and eventually TTC was selected based on the desire for “as many students as possible to get into their top choice school” (New Orleans Recovery School District 2012a). Vanacore (2011) and Vanacore (2012) provide additional details."

In conclusion:

"In the field, there is growing momentum for DA over TTC (see Abdulkadiroglu 2013 and Pathak 2017). This trend may be driven by a first-mover advantage of DA and its use in other contexts. New York City and Boston adopted DA in 2003 and 2005, and DA is widely used in residency matching (Roth and Peranson 1999). In 2013, New Orleans also switched from TTC to DA. One of the most important reasons for this switch involved challenges in explaining how TTC handles priorities.  Under DA, officials could explain that an applicant did not obtain an assignment at a higher ranked seat because another applicant with higher priority was assigned to that seat. At the time of the change, a clear explanation of how TTC reflects priorities was not available.

"It remains to be seen whether TTC will be used in the field again. But policymakers cannot ignore efficiency, which TTC delivers but DA does not. For this reason, TTC should remain a serious policy option. Our formal results may make it easier to explain how TTC incorporates priorities. It’s possible that TTC would have been chosen in some settings with knowledge of this result, and at the very least, advocates now have a new argument in its favor."

Neil Dorosin and school choice in Brooklyn, in the WSJ

Neil Dorosin was the director of high school operations for the NY Department of Education, back when Atila Abdulkadiroglu, Parag Pathak and I helped them design a school choice system for high school admissions. He later became the Pied Piper of school choice when he founded the Institute for Innovation in Public School Choice, which led the effort to redesign choice in a number of American cities. He still lives in NYC, and he's also a dad. The WSJ has made him the poster boy (poster dad?) for this year's middle school choice in Brooklyn (which apparently has some recently introduced random elements):

School-Choice Expert Has Unique Take on Brooklyn District’s New Admissions System
Neil Dorosin’s daughter went through the middle-school process and landed at a charter; ‘It was a complicated decision’
By Leslie Brody, Sept. 21, 2019

"His family’s choice gives a glimpse into how families grapple with decisions as Mayor Bill de Blasio ’s administration experiments with ways to better integrate one of the nation’s most segregated school systems. The School Diversity Advisory Group, appointed by the mayor, cautioned last month that if the city public schools lose students to private schools or other options, “it will become even more difficult to create high-quality integrated schools that serve the interests of all students.”

School choice in Washington D.C., by Thomas Toch in the Washington Post magazine

In the Washington Post magazine, Thomas Toch writes about the accomplishments and limitations of the school choice system in Washington D.C., and school choice more generally. He's a thoughtful observer of the education scene, and the director of FutureEd. (I gather that the piece is only online now and will be in print on Saturday...)

The Lottery That’s Revolutionizing D.C. Schools
by Thomas Toch.  Photos by Evelyn Hockstein, MARCH 20, 2019

The whole thing is worth reading.  Here's the concluding paragraph:

"In forcing traditional public schools to compete more directly, the common enrollment system has pressed them to strengthen themselves, as Henderson suggests. It has made school choice fairer and more efficient. And it has changed the dynamic between Washington’s public and private schools. Families are finding public Montessori programs, dual-language opportunities like Noah’s and other options that were offered mainly in the private sector in the past. But the long wait lists at some schools and empty spots at others that the My School DC lottery has produced make clear that the success of school choice in Washington will ultimately require creating more strong schools. “If we don’t have capacity in A-plus schools for all the kids, then some kids aren’t going to go to A-plus schools,” Roth told me. “No system of choice can fix that.”

School choice among different kinds of schools

Chalkbeat on the changing face of school districts, and the role played by universal-enrollment school choice:

A ‘portfolio’ of schools? How a nationwide effort to disrupt urban school districts is gaining traction

"Several years ago, Indianapolis Public Schools looked like a lot of urban school districts. The vast majority of students attended traditional public schools, though enrollment was dwindling, and the district had an adversarial relationship with its small but growing number of charter schools.

"That’s no longer true. The district is actively turning over schools to charter operators, and it’s rolling out a common enrollment system for district and charter schools that could make it easier for charters to grow. Nearly half of the district’s students now attend charters or district schools with charter-like freedoms.

...

"A growing number of philanthropists, advocates, and policymakers say the way to improve schools is to upend the traditional school district. Usually pointing to the same cities as models — Indianapolis, along with Denver, New Orleans, and Washington D.C. — they want to see more charter schools and more district schools run like charter schools.

...

"Another piece of the portfolio playbook is supporting enrollment systems that allow families to easily choose among district and charter schools.

"Adding new schools and new choices can make things harder on parents, who must navigate several enrollment processes to make a choice and get assigned to a school. Common enrollment systems create a single place to navigate it all — while also ensuring that all parents are exposed to new schools, and making it especially clear to district leaders which schools are attracting the fewest students.

“In addition to efficiency for families, unified enrollment helps the system make better decisions about which schools to replicate, recruit, incubate, scale, and maximize and, perhaps, where to locate them,” according to an Education Cities report.

"Denver, New Orleans, and Washington D.C. all have common enrollment systems, and Indianapolis just adopted one. In Denver, the use of a streamlined system did in fact increase enrollment in charters among low-income students and English-language learners, though in New Orleans parents said it was actually harder to navigate initially."

"Open algorithms" law proposed in New York City

Here is a bill that has been proposed (and sent to committee) by the New York City Council:
Automated processing of data for the purposes of targeting services, penalties, or policing to persons.
Title: A Local Law to amend the administrative code of the city of New York, in relation to automated processing of data for the purposes of targeting services, penalties, or policing to persons

Summary:

This bill would require agencies that use algorithms or other automated processing methods that target services, impose penalties, or police persons to publish the source code used for such processing. It would also require agencies to accept user-submitted data sets that can be processed by the agencies’ algorithms and provide the outputs to the user.

OneMatch for Indianapolis schools opens today

Here's an article that I think does an unusually good job of explaining both the benefits of a unified enrollment school choice system, and some of the objections it is facing as it is introduced.

1 Application Will Cover Enrollment For IPS And Indy Charter Schools  by ERIC WEDDLE.

"A new online enrollment system for families to enroll their kids in grades K-12 for the 2018-19 school year at Indianapolis Public Schools and most Marion County charter schools begins Wednesday.

"The so-called common enrollment process is a major shift for city parents and schools. Families will longer fill out separate paperwork for IPS magnet schools and neighborhood schools, or need to remember a smattering of enrollment deadlines among dozens of charter schools.

"Instead, families will log on to a website, pick the schools they want to attend, rank them in order by preference and wait to find out which school their child will attend. The first enrollment round begins Wednesday, Nov. 15, and ends January 15. Enrollment results will be announced February 15

"Cities, including Denver and New Orleans, offer a variation of the one-application approach. Support in Indianapolis has come IPS, the Mayor’s Office, most of the city’s charter schools and local education reform group The Mind Trust.

"As the new system has been rolled out some have raised concerns over the complexity and transparency of the process. 

"Caitlin Hannon, founder of Enroll Indy, the local nonprofit managing the OneMatch enrollment system, says it creates equity by simplifying where families get information about schools and using a computer algorithm to match a child with an open seat.

“It doesn't matter who your parent is,” Hannon says about how students are selected to attend schools with long waiting lists.  “It doesn't matter who you know or how much money you have or if you bake brownies for the school secretary.”

"The technology behind the system is similar to what is used for National Resident Matching Program through which most American doctors get their first job, according to the Institute for Innovation in Public School Choice which creates the algorithm used by OneMatch.

"Families are expected to use Enroll Indy’s website to find a school that matches their need and interest, such as it academic performance, after-school care and transportation options.

"Though OneMatch, also part of the Enroll Indy website, families can choose up to ten schools they would want their child to attend and rank the schools in priority.

"The algorithm factors in priories associated with each student -- such as whether they live in a pre-drawn school boundary zone, if a sibling already attends a school and if a parent works for IPS -- and assigns a random lottery number.

The system runs everyone’s choice at the same time and fills open seats based on those factors, Hannon says. IPS will no longer offer waitlist positions for programs that reach capacity. Rather, Hannon says, students will be assigned their top option based on availability.

“This is not about putting you in a school that isn't a school that you want,” says Hannon, a former IPS School Board commissioner. “This is about you telling us what you want, the priorities of the school, and your random lottery number. Those are the only three factors.”

"Unlike in the past, Hannon says, the system will also explain to families why they did not get the school they wanted.

"The new system requires all schools taking part to use a single enrollment application, follow three enrollment windows and use a random lottery process to select which students make it into popular academic programs.

"But not all Indianapolis charter schools are taking part, including Christel House Academy.

Carey Dahncke, head of schools, says the charter network is taking a wait-and-see approach to OneMatch for its two schools.

“Our enrollment has been strong, so the idea of changing practice just didn't seem necessary,” he says.

"Phalen Leadership Academy also did not sign on but two IPS innovation schools managed by the company will use OneMatch.

"The two networks will continue to enroll students using their own system and deadlines.

"The IPS Community Coalition, a group critical of ongoing changes within IPS, has described the OneMatch system as being akin to the dystopian Hunger Games series. In a recent Facebook post, the group said the enrollment system dictates schools choice, not the parents.

"The parents only provide the list of 10. This starts to look like some strange robotic, authoritarian system of the allocation of scarce resources (the 'good' schools), kind of like the Hunger Games. This looks like an inhumane system, not a parent and child-friendly one," the group wrote.

"In a public response, Hannon disputed the notion that families are not choosing their schools.

"We don’t decide anything for families -- they just apply and we run a lottery -- the same way it’s been done for years but in a more efficient place so families don’t have to apply all over the city," she wrote.

"Enrollment for 2018-19 will be held during three rounds: Nov. 15 - Jan. 15 with results on Feb. 15; Jan. 16 - April 15 with results on May 15; April 16 - June 15 with results on June 30. Late enrollment starts July 1.

Enrollment for IPS preschool students will continue to be handled by the SchoolMint application system."

School Choice in the District of Columbia: apparently not all according to algorithm

The Washington Post has the story: it seems that some politically connected families were able to get the schools they wanted without going through the school choice algorithm...

Secret report shows ‘special’ treatment for public officials in D.C. school lottery

"Former D.C. Public Schools chancellor Kaya Henderson routinely helped well-connected parents — including two senior aides to Mayor Muriel E. Bowser (D) — bend or break the rules of the District’s notoriously competitive school lottery to enroll their children at coveted schools, according to a confidential report obtained by The Washington Post.

The report, based on an investigation by the D.C. Inspector General’s Office, describes in remarkable detail how Henderson used her power as head of the school system to place the children of those with political clout at campuses they could not otherwise access through the random lottery, which every year leaves thousands of families on waiting lists for their desired schools.

Inspector General Daniel Lucas found that Henderson misused her authority by giving preferential treatment to seven of 10 people who requested special school placements for their children during the 2015 lottery season. The investigation did not examine the rest of Henderson’s tenure from November 2010 to September 2016.

[Read the confidential inspector general’s report obtained by The Post]

Henderson openly acknowledged in interviews with investigators that she gave special treatment to the children of government officials. Asked about the help she gave City Administrator Rashad M. Young, a top Bowser cabinet official whose salary is $295,000, Henderson said D.C. officials “do not necessarily get paid as much as we should.”

The former chancellor bestowed such favors even as she dismissed pleas for special consideration from those with less influence, such as a deaf Vietnamese immigrant whose request that her daughter be allowed to attend a school where she could practice sign language was rejected.

The findings could shake public confidence in the city’s school lottery, which has been held up as a national model. It also raises troubling questions for Bowser, whose defense of her cabinet officials’ roles in the scandal is undercut by details in the report."
...
"[This is how the D.C. lottery is supposed to work]".

School choice in Chicago: GoCPS

Here's an account from New Schools for Chicago:
Chicago Board of Education Approves the Single Application
"Yesterday, the Chicago Public Schools Board of Education voted unanimously in favor of moving to a single application for all public high schools in the city. This decision comes just after a recently released report from the Institute for Innovation in Public School Choice (IIPSC) and New Schools for Chicago outlining the feedback and recommendations of parents from across the city. "

And here's a news story from WTTW:

CPS Aims to Simplify High School Applications With New ‘GoCPS’ Model

"The Board of Education voted unanimously Wednesday to approve a new common application for students entering district high schools this fall. The new model, called “GoCPS,” is aimed at transparency and efficiency in that application process, according to CPS Chief Education Officer Janice Jackson.

“We cannot have a system that allows some people to feel that they can access with ease while others feel like it’s too complicated and choose to disengage," she said. "So moving forward, GoCPS allows us to bring more people into the fold, but it also allows us an opportunity to use technology to support them.”

In the current system, students can fill out multiple applications and receive offers from high schools.

With GoCPS, students will fil out a single application, rank their school choices and receive a maximum of two offers – one each from a selective and non-selective school. If they choose to reject those offers, students would go through the process a second time and receive new offers.

If those too are rejected, the student would be placed in their neighborhood school with the option to apply for a transfer within the first 20 days of the school year."

The Brookings school choice index

Brookings has released their school choice index:

The 2016 Education and Choice Competition Index

Denver won the top spot for large districts for second year in a row in the 2016 Education Choice and Competition Index (ECCI). The Recovery District serving New Orleans came in second. Denver and the Recovery District were the only two districts in the ECCI that receive grades of A on school choice.

Here are the top 12, of 112.

. 

Many of the school districts in the top 12 spots have had help from economists, including the top 5.  Much of that help has lately been organized through IIPSC, the Institute for Innovation in Public School Choice.

School choice discussion in Indianapolis

The Indy Star has the story:
Will Indy adopt central enrollment system for schools?

"A group is developing a one-stop enrollment system for Indianapolis schools but will the city’s largest education provider take part?

Indianapolis Public Schools leaders are weighing whether to join Enroll Indy, a nonprofit with plans to launch a unified enrollment process for IPS schools and charter schools within the district’s boundaries by next year.

The goal: Help parents find a school for their children in a city with growing options that feature charter schools, innovation network schools, magnet programs and more.

So far, IPS hasn’t made any commitments, though moving toward such a system is among the district’s priorities, IPS Superintendent Lewis Ferebee said.

“Whether Enroll Indy is the best fit for IPS to go down that path is to be determined,” Ferebee told IndyStar. “The concept itself could definitely benefit our families.”

Advocates for a central enrollment system say the way parents now shop for schools is disorganized. To find the best fit, parents must juggle different application deadlines and know what programs are out there, a daunting task with the city now playing host to more than 40 charter schools.

Wealthier families can find the process easier to navigate, placing lower-income families at a disadvantage, organizers say.

“If we’re going to say we have choice,” said Caitlin Hannon, Enroll Indy’s founder, “everybody should have equitable access to that choice.”

Hannon, a former IPS School Board member, said the group is hoping to launch its first application process next fall for the 2018-19 school year. But first it needs buy-in from the city’s schools, and Hannon started making her pitch to IPS this month.

A 2015 report by the Institute for Innovation in Public School Choice found that the city’s schools are in “intense competition to enroll students.”

“There is no incentive for IPS, for example, to tell parents about charter schools. Or for Ball State University to ensure families understand the IPS magnet school application,” according to the report. “In both cases, doing so would not be in their best self-interest. For families, though the distinction between authorizers is less important. Parents are looking for the best school for their child, regardless of who runs it. For them, not having the information in one easy-to-access place doesn’t make sense.”

Families would apply through Enroll Indy to any participating school, where they’d rank their school preferences and be matched with a program.

Hannon said families would be asked their priorities, such as location and where siblings attend. Students are then matched to the school “they want the most that they can get into, based on those priorities,” Hannon said.

“I like to explain it as all schools lotteries happening at the same moment…,” she said.

An analysis of a similar system run in Denver Public Schools found not enough seats existed in high-performing schools to serve demand. That meant students often were assigned to lower-performing schools than initially requested.

But the system would come with perks, Hannon said. Parents would no longer have to hold spots for their children at multiple schools, making it easier for administrators to plan staffing needs...."

School choice in Indianapolis

The Indy Star has the story on the changes to come: School choice made easier for Indy parents

"The good news is that change is coming. A new non-profit organization, Enroll Indy, launched by a Mind Trust Education Entrepreneur Fellowship, is working with Indianapolis Public Schools, the Mayor’s Office and the State Charter School Board to streamline the school application process for public school families. Its plan includes a new school information source for parents to learn about their options; a robust effort to work directly with families on navigating the process; a streamlined application that includes both IPS and charter schools; a shared deadline across all schools and a much-needed window of transparency into school enrollment.

For nearly a year, stakeholders in both IPS and the charter sector have worked together on recommendations focused on making enrollment more efficient, equitable and transparent. As such, Enroll Indy is poised to launch a system this fall that will dramatically improve access for all families.

This new system not only will make the enrollment process easier for all families, but it will provide robust data and information to our city as a whole. It will provide new information on the type of schools families want and where they want them, meaning districts and authorizers will be able to collaborate strategically to meet the needs of families, rather than starting schools with no information on the neighborhood’s needs or wants. This data also will enable us to ensure schools are behaving fairly and serving all students, not just those who are easiest to educate."

Common enrollment system launches in Detroit, primarily for charter schools

A school choice system in Detroit is starting with charter schools.
The Detroit Free Press has the story:
Common enrollment system launches in Detroit today

"The nonprofit Excellent Schools Detroit is launching a common enrollment system today that is designed to make signing up for school easier and more equitable for Detroit families.

"Parents of children entering kindergarten or ninth grade in the fall will be able to use the new system during a 30-day window starting April 1. More than 40 schools are on board, most of them charters, as well as one private school

"Detroit Public Schools was part of the planning process but is not participating. Spokeswoman Michelle Zdrodowski said the district is in a state of transition and whether it joins is a decision that should be made by a school board once the district transitions from emergency management back to local control.
...
"Common enrollment has been a hot topic for years in conversations about education reform in Detroit.

"In fall 2014, the nonprofit Institute for Innovation in Public School Choice issued a report that said Detroit should launch a citywide enrollment system.

"The report highlighted the complexity of Detroit's public school market, with roughly 100 schools in DPS,  dozens of charter school districts (made up of about 100 schools) and 15 schools in the EAA, the state reform district. It said the system is hard for parents to navigate and fuels unhealthy competition among schools for students.

"Families have been disappointed. Families have been hurt, and they don't feel a lot of trust in the different systems," said Maria Montoya, director of communications and strategic partnerships for Enroll Detroit. She was part of the team that helped design the common enrollment system in New Orleans, called OneApp, in 2012.

"The idea that their application will be fairly considered, and it's not a person (at a school) picking them out and saying, 'We don't need any more autistic kids,' it's really hard for them to believe."

"A committee that included officials from Excellent Schools Detroit, DPS, charter schools, the Education Achievement Authority, community groups and parents designed Enroll Detroit. It was built by the New York-based Institute for Innovation in Public School Choice and Acumen Solutions."

Boston Globe looks at school choice in Denver and New Orleans

In the Boston Globe, there's a nice story by Jeremy C. Fox that focuses on school choice in Denver and New Orleans and the work that IIPSC has done there: Denver’s unified school enrollments may offer Boston a lesson

"A few years ago, parents here faced a bewildering array of options when selecting their children’s schools. There were more than 60 enrollment systems within Denver Public Schools alone, and another set for the city’s charter schools, each with distinct timelines and applications.

The confusion discouraged many low-income families from choosing at all, while parents with greater resources took advantage of the complexity to “game the system” in their favor, residents said.

“It did not promote equity with families,” said Karen Mortimer, a Denver public education advocate. “If you were in the know, you got the better schools.”

But four years after the Mile-High City adopted a common enrollment system that provides one-stop shopping for traditional, charter, magnet, and innovation schools, parents praise the ease and convenience of finding the right match.

Interviews with Denver parents, educators, and community groups suggest that the city’s largely controversy-free adoption of unified enrollment offers lessons for Boston, where a similar proposal by Mayor Martin J. Walsh and school leaders has met with vehement opposition from some parents.
...
"Since Denver and New Orleans became the first US cities to unify enrollment in 2012, several other urban communities have followed.

Of about a dozen US cities that have attempted to adopt the system, half have stalled amid political conflicts, according to Neil Dorosin, executive director of the Institute for Innovation in Public School Choice, a nonprofit group that builds and implements school assignment systems."

A look back at school choice in New Orleans

Here's an article discussing IIPSC's work in New Orleans, in the Fall issue of Education Next:

The New Orleans OneAppCentralized enrollment matches students and schools of choice, By Douglas N. Harris, Jon Valant and Betheny Gross

"In the immediate aftermath of Hurricane Katrina, New Orleans families could choose from an assortment of charter, magnet, and traditional public schools. The city initially took a decentralized approach to choice, letting families submit an application to each school individually and allowing schools to manage their own enrollment processes. This approach proved burdensome for parents, who had to navigate multiple application deadlines, forms, and requirements. Moreover, the system lacked a mechanism for efficiently matching students to schools and ensuring fair and transparent enrollment practices. The city has since upped the ante with an unprecedented degree of school choice and a highly sophisticated, centralized approach to school assignment.

"Today, New Orleans families can apply to 89 percent of the city’s public schools by ranking their preferred schools on a single application known as the OneApp (see Figure 1). The city no longer assigns a default school based on students’ home addresses. Instead, a computer algorithm matches students to schools based on families’ ranked requests, schools’ admission priorities, and seat availability. Experience with the OneApp in New Orleans reveals both the significant promise of centralized enrollment and the complications in designing a system that is technically sound but clear to the public, and fair to families but acceptable to schools. The OneApp continues to evolve as its administrators learn more about school-choosing families and school-choosing families learn more about the OneApp. The approach remains novel, and some New Orleanians have misunderstood or distrusted the choice process. The system’s long-term success will require both continued learning and growth in the number of schools families perceive to be high-quality options."

Indianapolis schools discuss universal enrollment

Market design first steps: Report: IPS, Indy Charter Schools Should Use Same Enrollment Application

"A report out this week is urging the Indianapolis Public Schools district and city charter schools to consider partnering on a one-stop-shop approach for enrollment.

What the report found, basically, is enrolling in an Indianapolis public school -- be it IPS or a charter -- can be bewildering process for parents to navigate.

Students applying to an IPS magnet school have a different steps of enrollment based on whether they are new or returning to the district.

Some charters require in-person applications while others allow online submissions. The deadlines for all public city schools are not the same.

“If you think about applying for college, trying to navigate different deadlines and applications -- that is what it looks like for parents now in Indy,” said Caitlin Hannon, executive director of Teach Plus in Indianapolis which commissioned the a study of enrollment processes for IPS, charter schools and their authorizers.

The report, written by the Institute for Innovation in Public School Choice, says the IPS enrollment system and efforts by the city and local nonprofits to promote school options still leave parents and others confused.

Nathan Ringham, an IPS parent quoted in the report, said there is no one source to review deadlines, requirements or other issues related to enrollment.

“I shouldn’t have had to go to the state department of education to figure out the birth date cutoff for kindergarten,” he said. “I shouldn’t have to go to one page to see how we enroll as a new student and then another to see how to enroll in a magnet.”

In addition, enrollment projections by schools have been below target in past years because schools are unsure where students will attend until the school year begins. When teachers are hired months earlier based on flawed enrollment projections projections, they wind up being transferred to other schools or seeking another job, according to the report.

The institute and recommends that the city to consider a so-called common enrollment process. So rather than apply for multiple schools, a parent could fill out one application and rank their preference.

Cities, including Denver and New Orleans, offer a variation of the one-application approach that also provides information about each school, such as academic performance, so parents can compare schools.

“If the first choice is an IPS school and second is a charter and third is another charter -- that is fine,” Hannon said about how a common application would be filled out. “Then all of those would go into a lottery process where an algorithm is built and people are given their preferences by the way they have listed them and based on the requirements of each school.”

Data that could be collected in an open enrollment, Hannon said, could be used to identify whether a charter school is "creaming" -- taking the best students who apply -- or if students from one part of the city are seeking schools outside their neighborhood boundries. 

IPS Superintendent Lewis Ferebee has recently said he is open to discussing the common application."

IIPSC: the Institute for Innovation in Public School Choice

Over at the Dell Foundation (which funds a lot of work on public school choice), they have a Q&A on school choice and enrollment: Neil Dorosin and Gaby Fighetti from The Institute for Innovation in Public School Choice

"The Institute for Innovation in Public School Choice (IIPSC) is a nonprofit organization with a mission to support groups of people in cities in designing and implementing school choice and enrollment processes. They work with consortiums of people in cities to bring them through a process they call market design: creating a group of policies and operations that, when taken together as a whole, govern the way kids apply to and are accepted to schools.

IIPSC is hosting a conference on May 20, 2015 where education leaders from all over the country will gather to immerse themselves in unified enrollment theory and practice. Practitioners from cities that have already implemented or are implementing unified enrollment – Cleveland, Chicago, Denver, Detroit, Indianapolis, New Orleans, New York City, Newark, Oakland, and Washington DC – will be on hand to share their knowledge and experiences. The goal is for all participants to emerge from the conference with a concrete set of knowledge and tools to use in advancing this critical work in their own cities.

Neil Dorosin is the Executive Director and Gaby Fighetti is the Deputy Executive Director of IIPSC. Read more about their work below.

How has IIPSC effectively launched this current reform movement with unified enrollment?

Neil: IIPSC principals first worked together in New York City in the very early Joel Klein years, and in this environment there were almost no charter schools. This illustrates that the ideas within unified enrollment are not specific to any particular type of school- charter schools, district schools, non-public schools, etc. They are ideas that allow administrators to serve families better. To bring efficiency, equity, and transparency to enrollment and choice systems.

When we began working with Denver we realized that what we were doing requires district and charter sectors to work together in a whole new way, and these changes are fundamental to the way cities manage school choice and then hopefully implement portfolio reform strategy. We are committed to political neutrality and always make sure that people in cities know that our work is meant to advance healthy choice processes, not to advance any political position. We love the fact that people in cities all over the country now see the ideas and guiding principles of unified enrollment systems as things that they believe in and want to advance in their cities.

Tell us about the team who helped design the unified enrollment system.

Neil: Al Roth shared the Nobel Prize in economics for applying matching theory science to solve real world problems. Most famous examples include the Medical Residency match (matching residents and hospitals), kidney donor exchange programs (identifying compatible pairs of donors and recipients from VERY long waitlists, and saving many lives), and for unified enrollment work.Parag Pathak was his student, and is now a full professor at MIT. Atila Abdulkadiroglu co-wrote the seminal paper on the market design approach to school choice in 2003 and joined Al and Parag in the first schools project – in New York City in 2003. Al, Parag and Atila are all now members of our advisory board and active participants in our projects with cities.

It turns out that matching science can be adapted to solve these and other problems, and to make people’s live better in real and meaningful ways. We are motivated by this every day."

How Parents Experience Public School Choice

School choice in Detroit?

The Detroit Free Press has a story on the current debate: Common enrollment: Lessons for Detroit

When preparing to move to Washington, D.C., in 2012, Erika and Lamont Harrell spent so much time applying to charter schools that it felt like a full-time job.

They filled out 24 applications — a dozen for each of their two sons — and juggled different school websites and deadlines.

That was before My School DC, a common enrollment and lottery system that has one application and the same deadline schedule for most of the city's publicly funded schools, including charters. A week-long task one year turned into 20 minutes the next.

"The process is just so much easier, and it's less stressful," said Erika Harrell, 33.

More than 200 miles away, in Newark, N.J., the first days of the school year in September were marked by student and parent protests of a similar reform effort called One Newark. Some parents complained that their children were matched to far-away schools that they didn't put on their list.

Common enrollment — in which a computer algorithm tries to match kids to their top-ranked schools — is one of the main reform ideas bubbling out of the discussions around reshaping public education in Detroit.

Changing how kids enroll won't improve academics — a significant issue in a city where more than 80% of ranked schools in Detroit Public Schools are in the bottom quarter statewide. But supporters say it would give all families an equal shot at seats in sought-after schools, bring order to what is now a chaotic enrollment process and stabilize school rosters earlier in the year. The data gleaned from it could inform decisions on which schools should close.

Common enrollment can be tough to sell to parents, at least initially.

The cities that have common enrollment — such as Denver, Newark, New Orleans and Washington — offer lessons for Detroit.

Officials there say they have had significant successes in getting kids matched with their top-choice schools.

But no system is perfect. In Denver, for example, researchers say common enrollment has been stable and successful, but lingering gaps remain in terms of participation by minority, special-ed and low-income students. They also said the city needs more seats in high-performing schools to meet demand.

Improving choice for all students

Common enrollment works best when all or most schools are involved, experts say. The systems have centralized management.

In Denver, where common enrollment launched in 2012, 100% of public schools participate, including charters.

Denver officials say they're happy with how it's working. In the system's first three years, between 76% and 89% of all students were matched with one of their choices, and between 64% and 72% got their first choice school, according to a recent study by the Seattle-based Center on Reinventing Public Education.

"Previously ... we had over 60 application processes and time lines, so only the savviest of parents were able to take advantage of school choice," said Roberta Walker, manager of choice and enrollment for Denver Public Schools.

The school district was an early supporter. A promise of transparency (the system is audited annually) and some pressure from foundations that fund charter schools helped bring charters on board, said Mike Kromrey, executive director of the community group Together Colorado.

Denver Public Schools runs the system, called SchoolChoice.

Getting everybody on board could be stickier in Detroit. The city has a decentralized education system with roughly 100 schools within Detroit Public Schools, 64 charter school districts (made up of 98 schools) and a 15-school reform district for the state's worst schools.

And with a dozen charter authorizers, Detroit has far more than the other cities. In Denver, for example, the public school district is the only charter authorizer.

The charter sector has exploded in Detroit in recent years, leading to fierce competition for students.

"It takes a great deal of trust across schools for everybody to commit to a centralized process," said Betheny Gross, senior analyst for the Center on Reinventing Public Education.

"A charter school is not naturally going to be inclined to hand over their enrollment process. ... Each child comes with a bundle of resources that funds their school."

In New Orleans, the common enrollment system called OneApp brought order and transparency to a chaotic process. But in a city where about 95% of students attend charters, some of the highest-performing schools have opted out.

"If every school isn't going to be in it, it doesn't resolve the problem that it was created to resolve. It doesn't give you access to every school," said Karran Harper Royal, a New Orleans resident and outspoken critic of OneApp.

Supporters say common enrollment has made it hard for schools to "cream" students — using back-door methods to selectively admit children or push others out. A principal couldn't specifically seek out students with good test scores, for example.

"In the absence of any meaningful regulation, this stuff can happen all the time," said Neil Dorosin, executive director of the New York-based Institute for Innovation in Public School Choice. The group helps build common enrollment systems.

In Newark, common enrollment was attacked by some families who complained siblings were split up. Mayor Ras Baraka publicly blasted what he called superintendent Cami Anderson's "secret" algorithm. Anderson has argued that, despite some initial bugs, the system has improved school access.

Newark officials have since added a feature that will allow families to move all of their children to the same school, Dorosin said.

Centralized authority

In cities with common enrollment, one authority oversees the systems.

Whereas the public school system runs common enrollment in Denver, in Washington, D.C., it falls under the deputy mayor for education. New Orleans' system is run by the state reform Recovery School District, with input from the local Orleans Parish School Board. The state-operated Newark Public Schools district handles enrollment there.

The applications that parents fill out are processed by a central clearinghouse.

In contrast, a Detroit parent who wants to sign up their kid for a DPS school today has to make an in-person visit. Three schools require an entrance exam, and one a performing arts audition. About two dozen DPS schools require an application.

The city's charter schools have their own applications, due dates and lotteries.

"There's no coordination now. A kid can get into Cass Tech High School and four different charters. The schools often don't know if they're actually going to get that kid" until well after the school year starts, Dorosin said. "It makes it difficult (for schools) to plan."

Districts don't get the full amount of state funding for students who enroll after the fall count day.

The nonprofit education group Excellent Schools Detroit is pushing for a new commission to oversee school openings and closings, transportation and enrollment across the city. The proposal comes as the Coalition for the Future of Detroit Schoolchildren is facing a March 31 deadline to come up with proposed school reforms.

...

Implementing full common enrollment in Detroit would likely require legislative changes, experts say. But lawmakers might balk.

"The expansion of school choice and putting parents in the driver's seat has been the general path the government has been on. If recommendations were to come ... that restricted choice and artificially managed or regulated choice, I would ... think that many in the Legislature" would have serious questions, said Gary Naeyaert, executive director of the Great Lakes Education Project, a charter lobbying group.

Naeyaert said he believes "managed and regulated choice is not free and full choice."
