Predicting vocational performance of engineers from selected vocational interest,personality, and scholastic aptitude variables

The study examines the validity of the ACE and selected subscales of the EPPS and SVIB in predicting the vocational performance of engineers. Multidimensional criteria of vocational performance assessed from both external and internal frames of reference were employed. Six predictors were related to 17 vocational performance criteria; of the 102 tests that were made, 7 were found to be statistically significant. The results indicate that, in general, vocational performance cannot be accurately predicted by vocational interest, personality, and scholastic aptitude variables. The only consistent finding was that subjective ratings of vocational performance were predicted by SVIB Group V scores; a “self-esteem” interpretation was posited. Implications of the results for counselors and employers were discussed.
