Understanding Marine Corps ASVAB Scores

The Marine Corps uses your ASVAB scores in two primary ways: the **AFQT score** determines if you can enlist, while your **Line Scores** determine which Military Occupational Specialties (MOS) you qualify for.

Minimum AFQT Requirements

  • High School Graduates: Minimum score of 31.
  • GED Holders: Minimum score of 50.

Marine Corps Line Score Formulas

The USMC calculates composite scores as follows:

  • GT (General Technical): Word Knowledge + Paragraph Comprehension + Arithmetic Reasoning.
  • EL (Electronics Repair): General Science + Arithmetic Reasoning + Mathematics Knowledge + Electronics Information.
  • CL (Clerical): Word Knowledge + Paragraph Comprehension + Mathematics Knowledge.
  • MM (Mechanical Maintenance): Arithmetic Reasoning + Auto & Shop + Mechanical Comprehension.
  • ST (Skilled Technical): General Science + Word Knowledge + Paragraph Comprehension + Mathematics Knowledge + Mechanical Comprehension.

Common MOS Requirements

Different jobs require different minimum line scores. For example:

MOS Field Requirement
0311 Infantry GT 80+
0231 Intelligence GT 110+
6000 Aircraft Maintenance MM 105+
2800 Ground Electronics EL 115+
