This report describes plans for the development of a major longitudinal research database designed to support the development and validation of new predictors of Army performance, and also new measures of Army performance against which the new predictors can be validated. The following aspects of the database are addressed: (1) the anticipated data elements through Fiscal Year (FY) 1986/87 (the database will include already existing data on FY 81/82 enlistees and their training and scores on the Skills Qualification Test from the Army Enlisted Masterfile, as well as initial predictor measures, training measures, first and second tour performance measures, an experimental predictor battery, and Army-wide performance measures); (2) editing procedures for assuring the accuracy of the data entered, such as linkage to other files, elimination of duplicate records, individual field edits, and machine correction or imputation; (3) storage and access procedures, including the anticipated structure for primary soldier, applicant, sample soldier, soldier progress, field test, and task files, as well as updating procedures; (4) documentation and dissemination formats and standards; and (5) security procedures.
