The ASVAB comprises nine sections: arithmetic reasoning, assembling objects, auto shop, electronics information, general science, mathematics knowledge, mechanical comprehension, paragraph comprehension and word knowledge.
Each branch of the military has its own standards for admission into particular military occupations. They are represented by taking the composites of scores from different ASVAB test categories. One of these is GT, which is determined by the VE, or verbal score, plus arithmetic reasoning. The VE is derived from adding the paragraph comprehension and word knowledge scores, running them through a conversion table.
These Army occupations consider GT scores: diver (110), early warning systems operator (100), recruiting and retention (110), special forces (100 or 110, depending on specialization) and journalist (110).
Many Army bases have educational centers that offer FAST, or Functional Academic Skills Training. One of the programs offered under FAST is for GT score improvement, but admission means meeting certain standards. An applicant must already have a GT score between 100 and 110, and Test for Adult Basic Education, or TABE, reading and mathematics scores greater than 10.2.
The ASVAB is administered at most public high schools during 11th grade and is a good research tool for those interested in collecting data on general aptitude. In addition to its use in determining scores such as the GT for establishing military qualifications, the ASVAB and its scoring formulas and scores are used by the Department of Defense and some school systems for research.
