There is no overall "ASVAB Score." When you hear someone saying "I got an 80 on my ASVAB," they are talking about their AFQT (Armed Forces Qualifying Test) score, not an "overall" ASVAB Score.
Only four areas of the ASVAB test are used to compute the overall ASVAB score, also known as the AFQT (Armed Forces Qualification Test) score.
The four areas of the ASVAB used to compute the AFQT score are: Word Knowledge (WK), Paragraph Comprehension (PC), Arithmatic Reasoning (AR), and Mathmatics Knowledge (MK).
To determine the AFQT "raw score," first you have to compute your Verbal Expression (VE) score:
VE (Verbal Expression) = Scaled Score of WK+PC. To get the VE scaled score, add your Word Knowledge (WK) & Paragraph Comprehension (PC) score together, then use the below chart:
WK+PC VE Score WK+PC VE Score
0-3= 20/ 28-29= 42
4-5= 21/ 30-31= 44
6-7= 22/ 32-33= 45
8-9= 22/ 34-35= 47
10-11= 25/ 36-37= 49
12-13= 27/ 38-39= 50
14-15= 29/ 40-41= 52
16-17= 31/ 42-43= 54
18-19= 32/ 44-45= 56
20-21= 34/ 46-47= 58
22-23= 36/ 48-49= 60
24-25= 38/ 50= 62
26-27= 40/
The Overall ASVAB Score (AFQT Score) is a "percentile score."
The AFQT Raw Score is computed with the formula AFQT = 2VE + AR + MK.
You can't use the AR and MK score shown on your ASVAB Score Sheet. The Score Sheet shows "number correct" for your AR and MK Scores, because "number correct" is what is used for job qualifications. However, the military does not use this same score when computing the AFQT. They use the "weighted scores" of the ASVAB sub-tests for AR and MK. Harder questions in these areas get more points than easier questions. The "weighted scores" for AR and WK are not listed on the ASVAB score sheet given to you after the test, and I know of no way to retrieve that information from DOD.
The "raw score" is then compared to the below chart to determine overall ASVAB percentile score.
Std Score Percentile (AFQT) Std Score Percentile (AFQT)

121-124 2 205 51

If you want to determine what jobs you are qualified for, then you have to have a certain qualifing score in a certain area depending on the cereer field you are interested in. For the Army you would use DA PAM 611-21 to look up the MOS you want to do. In there it will give you the decription and the qualifing criteria to determine if you qualify for that particular MOS.
Hope this helps.
