The Duolingo English Test is a separate product by Duolingo that provides scientifically-proven language certification. The tests are extremely secure with remote proctoring, and the scores are extremely precise. The test is convenient and can be taken directly at home at the fraction of the cost of other recognized certifications.
Here is what Luis von Ahn had to say about it when it launched in beta:
"Every year, over 30 million job seekers and students around the world are forced to take a test to prove that they know English in order to apply for a job or school. For some, these tests can cost their family an entire month's salary. And not only that, taking them typically requires traveling to distant testing facilities and waiting weeks for the results.
We believe there should be a better way. This is why today I'm proud to announce the beta release of the Duolingo English Test, which was created to give everyone equal access to jobs and educational opportunities."
