Everyone taking the Duolingo English Test must now use a phone as a “secondary camera” during the test. This involves propping a phone against a heavy option and angling it in such a way that it can record the test taker’s screen and keyboard during the test.
This requirement seems designed to target remote-access cheaters. I guess Duolingo’s security team seem to believe they can detect when the action of a test taker’s fingers doesn’t match what is recorded from the screen.
I’ll take the DET before the end of the year to see how straightforward the setup is.
