A raw ASVAB score is also known as the Armed Forces Qualifications Test, or AFQT, which determines what branch of the military each individual qualifies for. AFQT is determined by the formula 2VE+AR+MK, where VE=WK+PC.
The minimum AFQT score accepted by the Navy is 35.
The Navy adds subtest scores into several combinations to determine your line score or composite score. These line scores determine the specific jobs in the Navy that you qualify to perform.
Your past experience does not necessarily qualify you for any specific job with the Navy. For instance, if you went to college to be an engineer, and your composite engineering ASVAB score (AR+2MK+GS) did not equal 210, you could not yet be an engineer with the Navy. You may retest.
If you wish to retest, you must wait one calendar month after your initial ASVAB test to take the retest. Your third retest can take place one calendar month after the second. Each subsequent retest can take place six months after the third retest.
There is not necessarily a "good" score on the ASVAB. Obviously, you must score a 35 to get in to the Navy, but your personal "good score" depends on what job you wish to have in the Navy.
For instance:
If you wish to be an Air Traffic Controller, your line score VE+AR+MK+MC or VE+MK+MC+CS must equal 220.
If you wish to be an Equipment Operator, your line score AR+MC+AS must equal 145.
If you wish to be a Culinary Specialist, your line score VE+AR must equal 88.
Don't know which job you want or wish to study for? Many recruiting offices have military career advisors. These individuals will give you information on each job available with the Navy. Job information also includes the line score required to perform each specific job in the Navy. Your military career advisor will help point your studies and your concentration in the direction that is best for you and best for the Navy.
