This study attempts to validate the findings of previous research predicting academic achievement from intelligence measures with the addition of objective personality factors. Regression analysis was used to affirm: (a) better predictions can be made utilizing both personality and intelligence measures than either alone; (b) there appears to be a change across time in the importance of each predictor; and (c) difference achievement areas are best predicted by unique combinations of personality variables.
