“…Whether or not the results will remain invariant for other samples from the same institution cannot be predicted until results of further research are known. Travers and Wallace (1950), for example, have found that the DAT battery have little value as predictors for one class in the University of Michigan School of Dentistry, but considerable value for another class. This phenomenon necessitates replications of the same study with succeeding classes in one institution, so that the effects of class peculiarities can be evaluated and eliminated from consideration in the analysis of data.…”

A total of 32 mental ability, past-achievement, manual skill, personality, and vocational interest variables believed to be potentially useful in the selection of dental students were factor analyzed to determine their factor pattern in relation to the criterion variable, the dental GPA Then those variables which shared common factors with the criterion variable were used as independent variables in a multiple-repression equation for predictive purposes For the 72 dental juniors studied, it was found that there were 2 common factors between the "predictor" variables and the dental GPA 1 factor, decided to be academic aptitude, was significantly loaded in 4 "predictor" variables besides the dental GPA The other factor, related to manual skill, was significantly loaded m .) subtext 1 ; of a manual skill test and the dental GPA All but 1 of the 7 "predictor" variables were used in the predictive equation, 1 \aridblu being dropped because of its low, though statistically significant, factor loading Ol all the variables, the predental GPA was found to be the most important predictor of success in dental school.

“…He maintained that it might be more profitable to devote time to a study of the criterion than to the proliferation of new tests which are somehow hoped will be more valid than previous ones. Travers and Wallace (153) pointed out that inconsistencies in validity may arise from the process of selection.…”
