Evaluating the Appropriateness of the Numerical Operations and Math Knowledge Subtests in the AFQT
Published Date: November 1, 1986
The Numerical Operation (NO) subtest, used in the Armed Forces Qualification Test (AFQT), has a history of causing problems for the Armed Services Vocational Aptitude Battery (ASVAB) score scale. Two adjustments to the ASVAB score scale have been required since NO was made part of the AFQT in 1980. The purpose of this report is to present evidence that the NO subtest should be deleted from the AFQT and be replaced by the Math Knowledge (MK) subtest. Data are presented showing that the AFQT scores in 1984 were inflated by approximately three percentile score points.
