To develop General Aptitude Test Battery (GATB) norms for the occupation of photograph finisher, 59 female workers employed as photograph finishers in Wisconsin were administered all 12 tests of the GATB and the Research Questionnaire-Background during July 1969. Supervisory ratings of job proficiency were made at approximately the same time as the tests were administered. Minimum aptitude requirements were determined on the basis of job analysis and statistical analysis of aptitude mean scores, aptitude-criterion correlations, and selective efficiencies. Norms of 90 for verbal aptitude and 75 for form perception were established. Only 68 percent of the nontest-selected workers were rated as good workers, and 32 percent were rated as poor workers. If the workers had been test-selected with the aptitude norms of 90 and 75, 82 percent would have been rated as good workers, and 18 percent as poor workers. The Job Performance Rating Form and fact sheet for the occupation of photograph finisher are appended. (SB)
