These scores include your Armed Forces Qualification Test (AFQT) score as well as your scores on each of the 9 individual subtests that make up the ASVAB. When you get your report, the most important score you will want to look for first is your AFQT score. This score determines your eligibility to serve in the military and to enlist in the U.S. Marines you need to have achieved a score of at least 32.
One ASVAB sub-measure, the Armed Forces Qualification Test (AFQT)--which is just a separate analysis of the same tests that focuses only on four of the subtests--is also population-referenced, but its score from 1-99 is a percentile score. This means that if you score a 73, you scored as well as or higher than 73% of test-takers in the national sample.
