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 for the Marine Corps are as follows:
CL- Clerical, Administrative, Supply & Finance - NO + CS + VE (Note: CL Score was eliminated in late 2002. All job Marine Corps requirements that required a CL score were changed to GT Score at this time. The score requirements are the same. In other words, if a job previously required a CL score of 90, then it was changed to require a GT score of 90).
EL -Electronics Repair, Missile Repair, Electronics and Communications -GS+AR+MK+EI
MM - Mechanical Maintenance, Construction, Utility and Chemical Maintenance (hazmat) - GS+AS+MK+MC
GT - General Technical, Special and Officer Programs - VE+AR
