The project
Admissions systems are a form of public infrastructure
Coordinated choice and assignment systems connect families' preferences with schools' or universities' places and priorities. Their design affects how people search, apply and gain access to education.
The research documents their adoption and design across 149 countries and more than 600 cities. CCAS Wiki provides a living environment for exploring systems and evidence; its evolving catalog is broader than the fixed research sample.
What the work involves
Map adoption
Compare where and when coordinated admission systems have been introduced.
Compare design choices
Document how priorities, applications and assignment mechanisms differ across settings.
Connect systems and evidence
Make comparative information available alongside research that can inform policy design.
Research & implementation
A review paired with a living platform
The documented adoption data span 1950–2023, while the website continues to develop. Research-sample counts describe the review and should not be confused with the number of countries tracked by the live catalog.
