This study assessed the Armed Services Vocational Aptitude Battery (ASVAB) predictors of student success in the diagnostic imaging course at the Air Force's School of Health Care Sciences. Regression analyses provided two significant predictors (p < 0.05) of student success as identified by final grade. Those predictors were the mechanical and electronics scores on the ASVAB. Also, both scores were significantly different (p < 0.05) among those who passed, washed back (passed but required excess time), and disenrolled. Because a significant number of individuals take the ASVAB, entry-level radiography programs should consider using these predictors for admissions decisions.
