The US Armed Forces Qualifying Test (AFQT) score is used in the recruitment to the US Armed Forces. Scores from the Armed Services Vocational Aptitude Battery are used in the computation of the score.
The ASVAB contains nine sections:
- General Science (GS)
- Arithmetic Reasoning (AR)
- Word Knowledge (WK)
- Paragraph Comprehension (PC)
- Mathematics Knowledge (MK)
- Electronics Information (EI)
- Auto Shop (AS)
- Mechanical Comprehension (MC)
- Assembling Objects (AO)
Until 2002, "Numerical Operations" was also administered on ASVAB, but has been dropped. "Assembling Objects" is new as of 2002.
AFQT Scores are divided into the following categories:
- Category I - 93-99
- Category II- 65-92
- Category IIIA - 50-64
- Category IIIB - 31-49
- Category IVA - 16-30
- Category IVB - 10-15
- Category V - 0-9
The formula for computing this AFQT score is: AR + MK + (2 x VE). The VE (verbal) score is determined by adding the raw scores from the PC and WK tests (i.e., how many questions the aspiring recruit got right on each) 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 all other examinees. Thus, someone who receives an AFQT of 55 scored better than 55 percent of all other examinees.
Law prohibits applicants in Category V from enlisting[How to reference and link to summary or text]. In addition, there are constraints placed on Category IV recruits. Presently, all Category IV recruits must be high school diploma graduates. Further, the law constrains the percentage of accessions who can fall in Category IV (currently, the limit is 20%).
