This research memorandum examines the validity of the Armed Services Vocational Aptitude Battery ASVAB against several measures of infantry performance collected as part of the Job Performance Measurement JPM project. ASVAB was highly related to hands-on performance of critical infantry tasks, written infantry job knowledge tests, and grades in initial infantry training courses. The validity of ASVAB was also found to extend into the second term of service by being able to predict the performance of infantry unit leaders. Experience in the Marine Corps, as measured by time in service, rank, and recency of task performance, had a significant and positive influence on infantry performance. Despite such developmental effects, experience was not able to overcome the significant performance differentials found between low- and high-aptitude personnel. The Marine Corps JPM project succeeded in developing reliable, objective, and representative measures of infantry performance. The results of the project provide the Marine Corps with convincing empirical evidence that demonstrates the strong linkage between performance on the ASVAB and future infantry performance.
