This study dealt with the problem of investigating the validity of two recently developed paper-and-penci1 tests of programmer aptitude , the Aptitude Test for Programmer Personnel (ATPP) and the Computer Programmer Aptitude Battery (CPAB), in predicting success in computer programming.

Subjects were 34 computer programmers employed in a major computerized tax processing company. Scores in the Computer Programmer Aptitude Battery (CPAB) and ratings of each programmer's job performance by his immediate supervisor were obtained. The purpose of the study was to validate a selection test. The relationship between the aptitude battery and performance evaluations was examined to evaluate the test's ability in predicting programming performance. Statistical treatment of data included Pearson product-moment correlations and a multiple linear regression analysis. The total test scores and several of the subtests were found to be significantly correlated with performance.
