The Air Force Vocational Interest-Career Examination (VOICE) was standardized on a sample of 12,000 10th, 11th, and 12th grade students, to calibrate the instrument with respect to the total Air Force applicant pool. Separate norms were developed for subsamples identified by school grade, sex, racial background, and geographic area. Major tasks involved sample construction, VOICE administration, and data analysis. Variables were stratified according to geographic regions, population density (urban or rural), school size, and type of control (public or private). In order to achieve a proportionate representation of black students, the sampling plan was designed to maximize the possibility of their selection. Although the number of black students participating was considerably less than planned, it was sufficient for establishing national norms. The results indicated that the extent of spread on any scale did not appear to distinguish between groups; and that differences in standard deviations were not consistent with respect to scale or group. Except for predictable male-female differences, the actual differences in number of points were usually small. Implications for vocational counseling and for further studies are briefly discussed.
