This app tests your knowledge of any of 164 languages and provides an official PDF certificate of proficiency with your CEFR score (Common European Framework of Reference for Languages).

You can take the test in your mother tongue, with 144 mother tongues supported.

There are two testing options available:

1) Free. You can take the Comprehensive (non-adaptive) test in any language, containing 882 quizzes, and receive a free certificate of proficiency with your CEFR score upon completion. The comprehensive test is the largest such test in the world and takes about 60 hours to complete. You can do the quiz at your own pace, over as many days as you like. With the free test, you can also compete against other test-takers around the world, and a leaderboard displays your ranking.

2) Paid. For a low fee, you can take our Rapid adaptive test, which will provide you with a certificate of proficiency with your CEFR in just 45 minutes. The rapid test uses questions that are progressively more difficult to accurately gauge your level of proficiency.

This app does not teach any language. It assumes that you already have sufficient knowledge of a language and specializes in assessing your proficiency.

Each official certificate is in PDF format, and contains your overall CEFR score, as well as your CEFR score for each functional area: Reading, Writing, and Listening. The PDF certificate contains a link to the official version of your certificate, stored for perpetuity on our secure servers, so you can make your results available to your employer, school, etc.
