Subjects were 38 computer programers employed in a national food-retailing corporation. A job analysis provided a basis for criteria development and served to guide the selection of predictors. Ratings of each programmer's job performance by his immediate supervisor, and scores on such tests as the Computer Programer Aptitude Battery (CPAB), clerical tests, and supervisory judgment test were obtained. Relationships between tests and criteria were examined to find the best test combination for predicting programming performance. Statistical treatment of data included a principal components analysis of the criteria and a multiple linear regression analysis. A weighted combination of the CPAB Reasoning, a test of clerical ability, and supervisory judgment test was found to be highly correlated with performance (R = .60).
