The ASVAB (Armed Services Vocational Aptitude Battery) is scored using both raw scores and composite scores that determine military service eligibility and job placement. Your raw score is calculated by counting the number of questions you answer correctly across nine subtests: General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Mathematics Knowledge, Electronics Information, Automotive and Shop Information, Mechanical Comprehension, and Assembling Objects.
These raw scores are then converted to scaled scores ranging from 1 to 99, with 50 representing the national average. The AFQT (Armed Forces Qualification Test) score—composed of Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Mathematics Knowledge—is particularly important because it determines whether you qualify for military service at all. You typically need a minimum AFQT score (usually 31) to enlist, though standards vary by branch and current recruitment needs.
Military branches also use line scores or composite scores, which combine specific subtests to evaluate your qualification for particular military occupational specialties (MOS). For example, the Navy uses different composite scores than the Army. Your overall ASVAB percentile ranking compares your performance to a nationally representative sample of test-takers, helping the military identify your strengths for job placement.
The test is computer-adaptive for the standard ASVAB, meaning question difficulty adjusts based on your previous answers. Scores remain valid for two years and can be retaken if needed to improve qualification or job eligibility. You receive a detailed score report showing performance across all areas, which counselors use to discuss suitable military career paths.
