Project A is the Armys long-term program to develop a complete personnel system for selecting and classifying all entry-level Army enlisted personnel. During the Concurrent Validation phase, a wide variety of predictor and criterion measures were administered to 9,500 soldiers in various military occupational specialties MOS. These data were used to refine a model of job performance for entry-level personnel in terms of five basic components MOS- specific technical skills, general soldiering skills, effort and leadership, personal discipline, and military fitness and bearing. This report describes efforts to develop from these components a composite index of performance to use in determining the validity of the Trial Battery measures for each job. Experiments were conducted to determine the best methods of weighting the basic components for an overall composite index weighting judgements were then gathered from a sample totaling 712 of officers and noncommissioned officers NCOs familiar with each Project A MOS. Analysis of these data showed that both scaling methods tested direct estimation and conjoint paired-comparison produced highly reliable construct weights, with the conjoint method slightly favored. There was relatively high agreement, although sometimes different emphasis, between the officer and NCO judging groups.
