Education quality is compared by country through learning outcomes, completion, assessment coverage and multi-study evidence rather than one universal index.

Top Performing Education Systems Over Time
Education systems are compared over time using PISA, TIMSS and PIRLS results across subjects and cycles rather than relying on a single current ranking.
