The EF English Proficiency Index (EF EPI) attempts to rank countries by the equity of English language skills amongst those adults who took the EF test.[2] It is the product of EF Education First, an international education company, and draws its conclusions from data collected via English tests available for free over the internet.[3][4] The index is an online survey first published in 2011[5] based on test data from 1.7 million test takers.[6] The most recent edition was released in November 2023.[7][8]
