The Center for American Progress, a DC think tank, reviews school choice:
Expanding Access to High-Quality Schools
Implementing School Choice Algorithms
From the introduction:
"According to a 2017 analysis by the Brookings Institution, the proportion of large school districts that offered school choice doubled from 2000 through 2016.1 As a result, of the more than 50.1 million students nationwide who attended public schools over the 2015-16 school year, more than 2.8 million students attended public charter schools, and more than 2.6 million students attended magnet schools. Additional students attended other types of public schools of choice, such as those with specialty or thematic programs.
...
"A centralized system can simplify enrollment for both families and schools. Students apply through a single application, ranking a list of schools that they would like to attend and receiving a single offer to one of their preferred schools. However, system design matters when it comes to centralized enrollment. Depending on how a district assigns an offer for each student, some families can unfairly manipulate the system to make it more likely that their child secures a seat at a more in-demand, usually better-performing school.
To reduce this risk of strategic manipulation in centralized enrollment systems, Atila Abdulkadiroglu, Parag Pathak, Alvin E. Roth and Tayfun Sönmez—economists with expertise in game theory and market design—proposed a solution. They designed two fair and efficient matching algorithms—or a set of rules and calculations—to ensure that, given the preferences of all other students and schools in the system, each student receives a single offer with his or her best possible school match. Specifically, the economists designed two matching algorithms suitable for centralized assignment: deferred acceptance (DA) and top trading cycles (TTC)."
