This research evaluated 24 predictors, including experimental tests administered in a technical classification assessment center TCAC, biographical variables, and Armed Services Vocational Aptitude Battery ASVAB tests, for classifying personnel for general detail GENDET billets in the Navy. Enlisted history data were extracted for 991 GENDETs who had taken the TCAC tests. Major criteria included supervisors marks and job history variables. Predictor validation was carried out using multiple regression with a double cross-validation paradigm. The TCAC tests added to the predictiveness of ASVAB and biographical variables for supervisors marks, but all of the job history criteria were better predicted by combinations of ASVAB and biographical variables than by ASVAB, biographical, and TCAC variables. Because this and other research shows that job history variables are much better criteria of job performance than are supervisors marks, further research with TCAC tests for selecting GENDETs is not warranted.
