EF English Proficiency Index
The EF English Proficiency Index (EF EPI) is a report which attempts to rank countries by the average level of English skills amongst adults. It is the product of EF Education First, a global language training company, and draws its conclusions from data collected via English tests available for free over the internet. The report was published for the first time in March, 2011 based on the results of over 2 million test takers. The second edition was released in October, 2012 and the most recent edition was released in November, 2013.
The EF EPI third edition was calculated using test data from 750,000 test takers in 2012. The test takers were self-selected and no demographic information was collected on them. The tests are used by the company for marketing and placement purposes. 58 countries and 2 territories appear in the third edition of the index. In order to be included a country was required to have at least 400 test takers total.
The report is composed of a country ranking table, several pages of analysis with graphs correlating other economic and social factors with English proficiency, and analysis of 10 countries and 1 territory. The 2013 report includes a retrospective look at evolution in English proficiency over the period from 2007 and 2012 based on a data set of 5 million test takers. The website displays portions of the report and has in-depth profiles of the role of English in several countries and territories.
- Exports per capita, Gross National Income per capita and Ease of doing business all correlate positively with English proficiency.
- English proficiency levels are evolving at different rates in different countries around the world, including a few countries with declining English skills.
- Europe as a whole speaks the best English, Latin America the worst.
- The size of the investment in English training does not necessarily correspond to the amount of progress made over time.

The EF English Proficiency Index has been criticized for its lack of representative sampling in each country. The report states that participants in the tests are self-selected and must have access to the internet. This pushes the index towards the realm of an online survey rather than a statistically valid evaluation.
However there are few alternative comparisons available of countries by their English skills, and those that exist are smaller in scale, as is the case with a reported British Council study, or they have other sampling flaws, as is the case with rankings of countries by standardized English test scores such as the TOEFL. The European Commission performed a language survey, SurveyLang, which tests a representative sample of 15 year old European students on their foreign language skills. The first report and data sets were released for 13 European countries in June 2012
