This study was conducted by the USAF Occupational Measurement Center to help validate the curriculum of Air Force officer pre-and postcommissioning professional military education (PME). More than 10,000 officers, from lieutenant through colonel, were surveyed to gather data on (1) leadership, management, and communication tasks performed; (2) the relative difficulty of those tasks; (3) perceptions of need of various PME topics for job and career; and (4) perceptions of benefits from PME. In general, tasks and topics related to commuication skills were rated as most performed and most needed, respectively; military and defense-related topics as the least needed. Perceptions of benefits from PME courses were mixed, but the greatest benefits were received in residence PME programs. Based on the survey data, there is sufficient rationale for the continuation of a multiphased PME program. Further, the various data provided will assist planners and evaluators in developing PME curricula and evaluating their effectiveness in meeting the professional needs of Air Force officers.
