| Abstract: | Sex and ethnic group differences were examined on the operational composites and tests used to select applicants for US Air Force officer commissioning programmes and for pilot training. Results showed that large mean score differences in applicant samples were substantially reduced among the pilot trainees. Despite differences in test performance, there was no evidence of differential validity for groups. When group differences in predicted pilot training completion rate were observed, performance was overestimated for the minority group relative to the majority group. When regression equations were adjusted for unreliability of the predictors, the observed differences in intercepts were reduced or eliminated. No prediction bias was observed against the minority groups. |
