Can I Use Grammarly in Duolingo English Test?

One common question among test-takers is whether they can use Grammarly during the test. The simple answer is no - Grammarly or any other writing assistance tools are strictly prohibited during the Duolingo English Test.

Understanding Duolingo English Test Integrity

The DET is designed to evaluate your genuine English language abilities. Using any external tools, including grammar checkers, spell checkers, or writing assistants like Grammarly, is considered a violation of test integrity. The test must reflect your actual language skills rather than the capabilities of supporting software. Duolingo English Test maintains high standards of academic honesty to ensure that test scores accurately represent candidates' true abilities.
