Finding your Marine Corps Job (MOS)
To join the Marine Corps as an enlisted member, you must usually take the Armed Services Vocational Aptitude Battery (ASVAB) test and get a good score. The maximum ASVAB score is 99. For enlistment into the Marine Corps, you must get a minimum ASVAB score of 35.
Each Marine Corps job is given a code known as a military occupational specialty (MOS). Every MOS has different ASVAB score requirements.
The ASVAB test actually consists of several different subject areas or subtests. They are general science (GS), arithmetic reasoning (AR), word knowledge (WK), paragraph comprehension (PC), mathematics knowledge (MK), electronics information (EI), auto and shop information (AS), mechanical comprehension (MC) and assembling objects (AO).
Note: The data listed here is subject to change and is only an example of how ASVAB scores are related to job selection for the Marines.
Marine Corps Line Scores
After you take the ASVAB, the Marine Corps translates your results into five calculations known as “Marine Corps line scores.” The line scores help the Marine Corps know which Marine Corps jobs, or Military Occupational Specialties (MOS) you qualify for. They are broken down into: clerical, electronics, general technical, mechanical maintenance and skilled technical.
CL -- clerical: VE+AR+MK
EL -- electronics: GS+AR+MK+EI
GT -- general technical: VE+AR
MM -- mechanical maintenance: NO+AS+MC+EI
ST -- skilled technical: GS+VE+MK+MC
