RELATED REPORTS
The EF EPI research series has three separate reports: the main EF EPI which looks at adult English proficiency, the EF EPI for companies (EF EPI-c) which examines workforce English, and the EF EPI for students (EF EPI-s) which tests high school and university students around the world. This year, we have published the EF EPI fourth edition and the EF EPI-c second edition. The EF EPI-s first edition will be published in 2015.
