About the Marine Corps

With the exception of the Coast Guard, the Marine Corps is the smallest military service and only needs to enlist about 38,000 new recruits per year (compared with the Army's average 80,000 yearly recruiting ​goal).

The Marine Corps requires a minimum ASVAB score of 32 to enlist. However, over the past four years, about 68.9 percent of all new Marine recruits have scored a 50 or above.

The Corps recruiting regulation only allows about five percent of their enlistees per year to join without a high school diploma. However, during Fiscal Year 2009, 99 percent of new Marine recruits had a high school diploma or at least 15 college credits. To even be considered for a GED enlistment, an applicant must score a minimum of 50 on the on the ASVAB (your chances are much better if you score at least a 90).
