In the first link, AAMC said Preview is "PREview scores offer a strong signal of non-academic risk (i.e., termination for non-academic reasons)." In the cited study, 13 out of 28,381 matriculants were dismissed for non-academic reasons and the median score for those 13 was 3. So by their logic, a 3 on Preview is at risk of non-academic dismissal. 13 out of 28,381 and they all that a strong predictor? They must be desperate to validate this stupid test.
