Analysis demonstrates how academic and non-academic factors predict optometry grades, suggesting effective evaluation methods.
Eighteen academic and 82 non‐academic variables, derived from 351 entrants to an optometry college in a three‐year period, were intercorrelated with the criterion, first‐year optometry school grade‐point‐average (GPA). Results showed that 17 variables were significantly (p<0.01) correlated with the criterion, pre‐tequisite GPA being the highest, r = 0.38, and that two factors were uncovered in the criterion, after factor analyzing the intercorrelations of the single criterion measure and these 17 variables, reflecting about equally two dimensions in the criterion measure, physics‐pre‐requisite overall GPA vs biology‐pre‐requisite‐overall GPA. Thus, pre‐requisite GPA was the most valid predictor of first‐year optometry grades and the best single variable to represent both factors.
