Most of the last minute discussion was about what priorities different kinds of students will have at different kinds of schools. That is something that is likely to be adjusted from year to year. But the nice thing is that the underlying choice architecture will make it safe for parents to state their true preferences however the priorities are adjusted.
From the press release: "The choice algorithm was designed with the help of a volunteer team of market design experts who have previously been involved in designing choice algorithms for school choice in Boston and New York City. Volunteers from four prominent universities contributed to the effort, including Clayton Featherstone and Muriel Niederle of Stanford University, Atila Abdulkadiroglu of Duke University, Parag Pathak of MIT, and Alvin Roth of Harvard.
“We are pleased that the district has decided to adopt a choice architecture that makes it safe for parents to concentrate their effort on determining which schools they prefer, with confidence that they won’t hurt their chances by listing their preferences truthfully,” said Niederle and Featherstone, the Stanford research team."
Here are Rachel Norton's comments (she's a school board member with a blog), and here's the story from the SF Chronicle. Here are some of my recent posts on school choice; many of the recent ones tell the SF story as it unfolded.
Now, on to implementation.
