Notes
1 The authors are independent reviewers; they were not funded for this review by Duolingo English Test or any of its competitors. The first author is currently conducting a TOEFL grant-funded study and the second author is currently conducting a GEPT grant-funded study.
2 Because there is very little published material about the goals and development of the test, much of the information here is based on Ye (Citation2014) and from the test’s webpage: https://testcenter.duolingo.com/. The screen shots illustrating the different task types are taken from Ye (Citation2014).
3 Again, because of the lack of publicly available information about the test’s development process, much of the information here is based on a phone conversation with one of the test developers (Burr, personal communication, February 9, 2015).
