Predictors of Success in High School Level Vocational Education Programs: A Review, 1954–1967

Over 1,200 correlations reported in 38 studies appearing in the period 1954–1967 are summarized for 10 predictor categories and 11 vocational program areas. For each predictor-program combination the distribution of correlations is given along with median correlation (r), total number of students involved, number of correlations located, and an index to the relevant studies. Main trends include (a) substantial variation in results from study to study; (b) differences in level of predictor-criterion r among vocational areas and between males and females; (c) evidence of differential predictability; and (d) poor performance of dexterity tests.
