EF SET powers the EF EPI research

The EF English Proficiency Index (EF EPI) is the world’s largest ranking of countries/regions by adult English skills. Published annually, the EF EPI is an important international benchmark for adult English proficiency. The EF EPI reports identify the most common pitfalls and highlight the most effective strategies for improving English proficiency. The EF EPI calculates a country’s/region's average adult English skill level using data from three different versions of the EF SET.
