Coordinated Choice & Assignment Systems (CCAS) — Global Review

A global review of how 149 countries use Coordinated Choice & Assignment Systems (CCAS) — the platforms and algorithms that match students to schools and universities when prices don't allocate access. It documents that about 60% of countries now use some coordinated mechanism (nearly double the last decade), maps the wide variation in how these systems are designed, and identifies evidence-based ways to make admissions more equitable and efficient. Findings are shared through an open, living data platform.

Target population

Students and families navigating school and university admissions worldwide; education policymakers

Key outcomes

  • First global, cross-level documentation of CCAS adoption across 149 countries
  • ~60% of countries use coordinated systems — nearly double the past decade
  • Identifies low-cost, evidence-based design improvements for equity and efficiency
