The EF English Proficiency Index (EF EPI) attempts to rank countries by the average level of English language skills amongst those adults who took the EF test. 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. The index is an online survey first published in 2011 based on test data from 1.7 million test takers. The most recent, seventh edition was released in November 2017.

Methodology

The EF EPI seventh edition was calculated using test data from 1 million test takers in 2016. 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. 69 countries and 3 territories appear in the sixth edition of the index. In order to be included, a country was required to have at least 400 test takers.

Findings

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 each region or continent. The 2016 report and accompanying country fact sheets include English proficiency levels by gender, age group, and region, within countries, and some English proficiency scores by city. The website displays portions of the report and has analysis of English skills in many countries and territories.

Primary conclusions

1. Exports per capita, Gross National Income per capita and innovation all correlate positively with English proficiency.
2. English proficiency levels are evolving at different rates in different countries around the world, including a few countries with declining English skills.
3. Europe as a whole speaks the best English, the Middle East the worst.
4. Women speak English better than men.

2017 rankings

Below are the latest country scores, proficiency bands, and rankings as published in 2017 (data from 2016).

Score calculation

On the web page of the company EF, the score calculation is explained: "In order to calculate a country's EF EPI score, each test score was normalized to obtain the percentage of correct answers for that test. All the scores for a country were then averaged across the three tests, giving equal weight to each test." There is thus no differentiation of the three tests for the calculation of the score.

Criticism

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. It is an online survey rather than a statistically valid sampling of the population.

However, there are few alternative comparisons available of countries by their English skills. 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.
