Standard Scores are scores that have a meaning relative to a national sample of youth aged 18 to 23. About half the population scores at or above a Standard Score of 50 and about 16% of the population scores at or above a Standard Score of 60.
AFQT scores are computed using the Standard Scores from four ASVAB subtests: Arithmetic Reasoning (AR), Mathematics Knowledge (MK), Paragraph Comprehension (PC), and Word Knowledge (WK).
AFQT scores are reported as percentiles between 1-99. An AFQT percentile score indicates the percentage of examinees in a reference group that scored at or below that particular score. For current AFQT scores, the reference group is a sample of 18 to 23 year old youth who took the ASVAB as part of a national norming study conducted in 1997. Thus, an AFQT score of 90 indicates that the examinee scored as well as or better than 90% of the nationally-representative sample of 18 to 23 year old youth. An AFQT score of 50 indicates that the examinee scored as well as or better than 50% of the nationally-representative sample.
AFQT scores are divided into categories, as shown in the table below.
AFQT Category | Score Range |
---|---|
I | 93 – 99 |
II | 65 – 92 |
IIIA | 50 – 64 |
IIIB | 31 – 49 |
IVA | 21 – 30 |
IVB | 16 – 20 |
IVC | 10 – 15 |
V | 1 – 9 |
