The ASVAB subtests for determining the composites are: General Science (GS), Arithmetic Reasoning (AR), Word Knowledge (WK), Paragraph Comprehension (PC), Numerical Operations (NO), Coding Speed (CS), Auto and Shop Information (AS), Mathematics Knowledge (MK), Mechanical Comprehension (MC), Electronics Information (EI), and Sum of Word Knowledge and Paragraph Comprehension, scaled (VE).
Current aptitude area composites used for MOS selection are as follows:
CL -Clerical-VE+AR+MK
CO -Combat-AR+CS+AS+MC
EL -Electronics-GS+AR+MK+EI
FA -Field Artillery-AR+CS+MK+MC
GM- General Maintenance-GS+AS+MK+EI
GT- General Technical-VE+AR
MM- Mechanical Maintenance-NO+AS+MC+EI
OF- Operators and Food-VE+NO+AS+MC
SC - Surveillance and Communications-VE+AR+AS+MC
ST- Skilled Technical-GS+VE+MK+MC
