Grader A: hit
Remote proctoring with head/eye-movement flagging (e.g. Proctorio, Honorlock) was in use at about half of surveyed US higher-ed institutions in 2020. Eye tracking for adaptive instruction stayed research-only, so the hit rests on proctoring counting as use in learning environments.
Test: at least 5% of institutions/students used gaze tracking in learning or assessment by 2024
Grader B: partial
Eye tracking for adaptive/attention-aware learning stayed in research and pilots. Remote proctoring (54% of US institutions in 2020) flags students looking away via webcam, but that is mostly face/head detection for exam integrity, not the poster's eye-tracking-for-learning sense. If proctoring gaze checks count, this would be a hit.
