The Armed Services Vocational Aptitude Battery ASVAB is routinely updated in order to replace obsolete items, to take advantage of advances of psychometrics, and to lessen the exposure of the battery to compromise. This paper documents the equating of new versions of the ASVAB Forms 11, 12, and 13 to ASVAB Form 8a, the reference test. The new tests were equated on a new score scale developed from a 1980 sample of American youth ages 18 through 23. The study describes the equating design, the methods used in equating the new forms to the anchor test, the description of issues surrounding the speeded subtests of the ASVAB, and a description of the resolution of the issues. Three equating methods were accomplished and compared for samples of military recruits and applicants. Results of the equatings revealed that a linear conversion table, based on applicants tested in the Military Entranced Processing Stations, would serve for five of the six new tests, and a linear conversion table based on linear equating of military recruits in Recruits Training Centers would be satisfactory for the remaining version. Special studies to adjust scores on the speeded subtests of the ASVAB are described in this paper, and resultant tables are presented.
