The ASVAB test is taken by individuals interested in joining the U.S. military. It may be taken by high school students in the 10th, 11th or 12th grade. Or, it may be taken by someone who has earned a GED or higher degree. Along with determining your suitability for enlistment, the score you receive on this test lets officials know what military occupational specialties you may qualify for.
Direct commission: civilians who have special skills that are critical to sustaining military operations and supporting troops may receive direct commissions. These officers occupy leadership positions in law, medicine, dentistry, pharmacy, intelligence, supply-logistics-transportation, engineering, public affairs, chaplain, oceanography and others.
You are tested in four critical areas — Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension and Mathematics Knowledge (see below) — these scores count towards your Armed Forces Qualifying Test (AFQT) score. The AFQT score determines whether you’re qualified to enlist in the U.S. military. Your scores in the other areas of the ASVAB determine how qualified you are for certain military specialties. Score high, and your chances of getting the specialty/job you want increase. The better score you get, the better chance you have of pursuing the specialty or field that you desire.
The test measures competency in 9 different subjects, which include General Science, Electronics Information, Auto and Shop Information, Mechanical Comprehension, Assembling Objects, Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Mathematics Knowledge. These last four sections- Word Knowledge, Paragraph Comprehension, Arithmetic Reasoning, and Mathematics Knowledge are the most important, as they make up something called the AFQT (Armed Forces Qualifications Test). An applicant’s AFQT score is what determines whether or not they are able to serve in the military at all, as each branch has minimum scores for enlistment.
Word Knowledge (WK), Paragraph Comprehension (PC), Arithmetic Reasoning (AR), and Mathematics Knowledge (MK). Scores on the AFQT are used to determine your eligibility for enlistment in the Army, Navy, Air Force, or Marine Corps. The other six test scores on the ASVAB tests are used to determine the best job for you in the military as your grades will demonstrate knowledge, skill, and interest in certain subjects and tasks.
One ASVAB sub-measure, the Armed Forces Qualification Test (AFQT)--which is just a separate analysis of the same tests that focuses only on four of the subtests--is also population-referenced, but its score from 1-99 is a percentile score. This means that if you score a 73, you scored as well as or higher than 73% of test-takers in the national sample.
