Job evaluation studies have been used by comparable worth advocates as a basis for sex-based pay discrimination litigation and as a vehicle to generate support for pay equity legislation. However, the adequacy of job evaluation measures for determining the relative worth of jobs has not yet been established; previous studies indicate deficiencies on various measurement criteria. The present study examines three methods of comparable worth job evaluation from a psychometric qualities perspective. Evaluation scores for 20 positions in a state agency were generated by four experienced analysts via each method. Reliability, discriminant validity, and convergence of the measures were examined in the context of comparable worth pay classification decision making. Results suggest that (a) reliability coefficients above .95 could still be inadequate for comparable worth job evaluation applications, (b) factor (dimension) redundancy is potentially a major shortcoming of job evaluation measures; (c) evaluation methods differ in terms of measurement quality, and (d) classification decisions are likely to be method dependent.This article is based on the author's dissertation, which was completed at Michigan State University.
