Two studies were conducted to determine the ability of the Project MINI-SCORE test battery to differentiate among graduates from different vocational curriculums and among graduates and dropouts from selected vocational curriculums. The population used in the first study consisted of 1,696 graduates from seven predominantly male and five predominantly female occupational curriculums. Analyses of variance of mean scores revealed that there were substantial differences among persons who enter and graduate from different vocational programs on dimensions measured by the test battery. A sub-sample from two male and two female curriculums was selected for further investigation. Analysis of data by means of correlation techniques revealed that specific attempts to predict whether or not persons could drop out of each of the four programs based on data from each instrument were not as successful. The studies revealed that the instruments are capable of differentiating among curriculums to a much larger extent than they are capable of differentiating among graduates and dropouts within a given curriculum.
