Armed Services Vocational Aptitude Battery

Trends in recruiting 1975–2001 showing total numbers of enlisted recruits in all branches of U.S. armed forces in light blue and percentage of recruiting goals met in dark blue. The percentage of recruits with at least a high school diploma is shown in gold, percentage with an above-average AFQT in orange, and the percentage called "high quality", with both a diploma and above-average AFQT score, is in purple.

The Armed Services Vocational Aptitude Battery (ASVAB) is a multiple choice test, administered by the United States Military Entrance Processing Command, used to determine qualification for enlistment in the United States Armed Forces. It is often offered to U.S. high school students when they are in the 10th, 11th and 12th grade, though anyone eligible for enlistment may take it.

History

The ASVAB was first introduced in 1968 and was adopted by all branches of the military in 1976. It underwent a major revision in 2002. In 2004, the test's percentile rank scoring system was renormalized, to ensure that a score of 50% really did represent doing better than exactly 50% of the test takers.

Categories

Format

The ASVAB contains nine sections and takes three hours to complete. The duration of each section varies between 7 and 39 minutes, the longest being for Arithmetic Reasoning. The test is typically administered in a computerized format at Military Entrance Processing Stations (MEPS) or in a written format at satellite locations called Military Entrance Test (MET) sites. Testing procedures vary depending on the mode of administration.

Computerized test format

• General Science (GS) – 15 questions in 8 minutes
• Arithmetic Reasoning (AR) – 15 questions in 39 minutes
• Word Knowledge (WK) – 15 questions in 8 minutes
• Paragraph Comprehension (PC) – 10 questions in 22 minutes
• Mathematics Knowledge (MK) – 15 questions in 20 minutes
• Electronics Information (EI) – 15 questions in 8 minutes
• Automotive and Shop Information (AS) – 10 questions in 7 minutes
• Mechanical Comprehension (MC) – 15 questions in 20 minutes
• Assembling Objects (AO) – 15 questions in 40 minutes
• Verbal Expression (VE) Score = (WK)+(PC)

Written test format

• General Science (GS) – 45 questions in 20 minutes
• Arithmetic Reasoning (AR) – 30 questions in 36 minutes
• Word Knowledge (WK) – 35 questions in 11 minutes
• Paragraph Comprehension (PC) – 15 questions in 13 minutes
• Mathematics Knowledge (MK) – 25 questions in 24 minutes
• Electronics Information (EI) – 20 questions in 9 minutes
• Automotive and Shop Information (AS) – 25 questions in 11 minutes
• Mechanical Comprehension (MC) – 25 questions in 19 minutes
• Assembling Objects (AO) – 25 questions in 15 minutes
• Verbal Expression (VE) Score = (WK)+(PC)

Navy applicants also complete a Coding Speed (CS) test.

Armed Forces Qualification Test

An Armed Forces Qualification Test (AFQT) score is used to determine basic qualifications for enlistment.

The AFQT scores are divided into the following categories

• Category I: 93–99
• Category II: 65–92
• Category III A: 50–64
• Category III B: 31–49
• Category IV A: 21–30
• Category IV B: 16–20
• Category IV C: 10–15
• Category V: 0–9

- The formula for computing an AFQT score is: AR + MK + (2 × VE).

- The VE (verbal) score is determined by adding the raw scores from the PC and WK tests and using a table to get the VE score from that combined PC and WK raw score.

- AFQT scores are not raw scores, but rather percentile scores indicating how each examinee performed compared with the base youth population. For example, if someone receives an AFQT score of 55 that means they scored higher than 55 percent of all other members of the base youth population. The highest possible percentile score is 99.

- The minimum score for enlistment varies according to branch of service and whether the enlistee has a high school diploma.

Minimum AFQT

	Tier I	Tier II
Branch	≥ HS Diploma	= GED
Army	31	50
Marines	31	50
Air Force	31	50
Navy	31	50
Coast Guard	40	50 with 15 college credits
*Army National Guard	31	50
*Air National Guard	50	50

GED holders who have earned 15 college credits in courses at the 100 level or higher are considered equivalent to those holding high school diplomas, so they need only the Tier I score to enlist. However, eligibility is not determined by the score alone. Depending on current recruitment goals an applicant may be required to achieve a higher score than the required minimum AFQT score in order to be considered for enlistment. Up-to-date information about eligibility requirements can be obtained from local recruiting centers.

Applicants in Category V are legally ineligible for enlistment. Applicants in Category IV must be high school diploma holders (unless they are needed to satisfy “established strength” requirements). The law limits the percentage of accessions who can fall between Categories IV and V (currently, the limit is 20% of all persons originally enlisted in a given armed force in a given fiscal year).

Composite scores

In addition to the ASVAB's AFQT, each branch has military occupational specialty, or MOS, scores. Combinations of scores from the nine tests are used to determine qualification for a MOS. These combinations are called "aptitude area scores", "composite scores", or "line scores". Each of the five armed services has its own aptitude area scores and sets its own minimum composite scores for each MOS.
