There is no overall "ASVAB Score." When you hear someone saying "I got an 80 on my ASVAB," they are talking about their AFQT (Armed Forces Qualifying Test) score, not an "overall" ASVAB Score.
The AFQT is important. It determines whether or not you can join the military. The AFQT score is not derived from all portions of the ASVAB. Indeed, the AFQT score is determined from only four areas of the ASVAB: Word Knowledge (WK), Paragraph Comprehension (PC), Arithmetic Reasoning (AR), and Mathematics Knowledge (MK).. The score is computed as follows:
The first step is to determine your Verbal Expression (VE) Score. This is done by adding the value of your ASVAB Word Knowledge (WK) Score to the values of your Paragraph Comprehension (PC) Score. This result is then compared to a chart which gives you your scaled VE Score.
The formula to derive the AFQT "raw Score" is 2VE + AR (Arithmetic Reasoning) + MK (Mathematics Knowledge).
It's important to understand here that the AFQT score is not computed with the AR "Line Score" and the MK "Line Score" that you see on your ASVAB scores sheet. The AR and MK scores shown on the score sheet is "number correct." However, the score used to compute AFQT score is the "weighted score," which takes into consideration the difficulty level of the question.
This formula results in the AFQT "raw score," which is then converted into a percentile score.
In 1980, a study, known as the "Profile of American Youth," was conducted by the Department of Defense in cooperation with the Department of Labor. DOD administered the ASVAB to a total of 11,914 individuals, ranging in age from 16 to 23, from July to October 1980. The purpose of the Profile of American Youth was to obtain data on the vocational aptitudes of current youth and to establish current national norms for the ASVAB.
The person's AFQT score is a percentile score, based on the population of test-takers in the above study. The percentiles are based upon a 99 point scale with 99 being the highest.
So, if an individual has an AFQT score of 50, then his/her AFQT "raw score" is better than 50 percent of the individuals who took the test in the above mentioned study.
AFQT Categories
For enlistment purposes, AFQT Scores are divided into the following categories:
Category I - 93-100
Category II - 65-92
Category IIIA - 50-64
Category IIIB - 31-49
Category IVA - 21-30
Category IVB - 16-20
Category IVC - 10-15
Category V - 0-9
In the early 90s, Congress passed a law stating that no Category V recruits could be accepted for enlistment in any of the military services, and no more than 20 percent of accessions could be in Category IV. Additionally, Congress required that any Category IV accessions had to be high school diploma graduates (no GEDs).
However, the military services have even stricter standards for enlistment. See our ASVAB Minimum Score Chart for minimum AFQT scores required to join each of the military services.
ASVAB "Norms" Updated
The last time ASVAB percentile scores were developed was in 1980. That means, folks taking the ASVAB today have their percentile scores computed based on the group who took the test 24 years ago. However, effective July 1, 2004, DoD has "re-normed" the ASVAB, which results in different overall scores for those taking the ASVAB after July 1. For details, see our article, The ASVAB has Just Gotten a Little Harder.
The ASVAB Test
The ASVAB contains nine separately timed sub-tests:
* General Science (GS) - 25 questions with an 11 minute time-limit.
* Arithmetic Reasoning (AR) - 16 questions with a 36 minute time-limit.
* Word Knowledge (WK) - 35 questions with an 11 minute time-limit.
* Paragraph Comprehension (PC) - 15 questions with a 13 minute time-limit.
* Auto & Shop (AS) - 25 questions with an 11 minute time-limit.
* Mathematics Knowledge (MK) - 25 questions with a 24 minute time-limit.
* Mechanical Comprehension (MC) - 25 questions with a 19 minute time-limit.
* Electronics Information (EI) - 20 questions with a 9 minute time-limit.
* Assembling Objects (AS) - 16 questions with a 9 minute time-limit.
The Marine Corps determines job qualifications from four separate composite scores made up from various sub-tests of the ASVAB. The Marine Corps Composite Scores are:
* Clerical (CL)- No Marine Corps enlisted job uses this composite anymore. In 2002, all enlisted MOS's which had a requirement for a CL composite score were converted to GT scores.
* Electronics Repair, Missile Repair, Electronics & Communications (EL) - Determined from General Science (GS), Arithmetic Reasoning (AR), Mathematics Knowledge (MK) and Electronic Information (EI).
* General Maintenance, Construction, Utility and Chemical Maintenance (MM) - Determined from General Science (GS), Auto & Shop (AS), Mathematics Knowledge (MK) and Electronics Information (EI).
* General Technical, Special and Officer Programs (GT) - Determined from Verbal Expression (VE) and Arithmetic Reasoning (AR).

From the cowardice that dares not face new truths,
From laziness that is content with half truths,
From the arrogance that thinks it knows all truth,
Good Lord, deliver me.
