"The purpose of this study was to furnish infantry, artillery, armor, and combat engineer research information for use in selecting new combat arms aptitude areas based upon the validity of ACB [Army Classification Battery] tests and a group of experimental predictors. Testing was accomplished in the 10th Infantry Division at the start of the training cycle for 1642 enlisted men later trained in combat arms military occupational specialties. Criterion ratings of estimated combat potential were collected after overseas maneuvers, one year after testing"--Preliminary page.

"The purpose of this study was to furnish interim combat engineer branch research information for use in selecting new combat arms aptitude areas based upon the validity of ACB [Army Classification Battery] tests, form 20 information, and a group of experimental predictors. Testing was accomplished in the 10th Infantry Division at the start of the training cycle for 71 enlisted men later assigned to combat engineer branch"--Preliminary page.

Matching the abilities of men entering the Army to the demands of training courses and jobs is an ever-critical problem facing Army personnel management. Aptitude area composites have been developed to measure the potential of the men, and the scores from these composites are used in making decisions about the men's assignments. The productivity of the men in their training and job assignments can be enhanced by obtaining more accurate assessments of their potential to perform in the different job categories. Based on a longitudinal study of the effectiveness of the Army classification battery (ACB) tests in predicting training success in military occupational specialty (MOS) courses, an improved set of aptitude area composites has now been developed. These composites and the benefits that would derive from their use are described in the present report.
