Development of a performance taxonomy for entry-level military occupations

U.S. Military services use the Armed Services Vocational Aptitude Battery (ASVAB) and other indicators to select and classify about 150,000 enlisted personnel annually. The effectiveness of these assessments can be difficult to gauge due to differences in criteria across services and occupations. We developed a cross-service job performance model to be used in development of measures of first-term enlisted job performance. We synthesized job performance research, starting with the services' Job Performance Measurement (JPM) projects (1980s-1990s) through recent projects, to form performance dimensions. The dimension structure was evaluated in a retranslation exercise with performance measurement experts. The resulting hierarchical taxonomy has three levels: (a) 33 dimensions, (b) 11 categories, and (c) four broad categories. The broad performance categories are: (a) Technical, (b) Organizational Citizenship and Peer Leadership, (c) Psychosocial Well-Being, and (d) Physical. A sample of military experts judged the importance of the 33 performance dimensions. Results showed that the four broad performance categories were highly relevant to each service and generalizable across services. While all dimensions were judged important, Psychosocial Well-Being dimensions were rated as the most important by each service. The dimension structure provides a framework for criterion development and future joint-service research.
