The Numerical Operations 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 3 percentile score points.
