Summary

This study of the validity of the Graduate Record Examinations (GRE) General Test used data from predictive validity studies that were conducted by the GRE Validity Study Service (VSS) in 79 graduate departments. The performance criterion was first-year grades in graduate school. Observed validities were computed, and for each graduate department validities were also estimated for groups at two other stages of selection--applicants for admission to the department, and all GRE takers. Two hypotheses were tested: (1) General Test's validities were equal across studies; and (2) General Test's validities had equal ratios across studies, i.e., the level of validities might vary from institution to institution, but the ratios would be constant. These hypotheses were applied for VSS groups, applicant groups, and all GRE takers, and implied validities were calculated. When the implied validities were compared to the observed validities, it was found that the assumption of equal validity did not account well for differences in the level of observed validity of the GRE General Test. The equal ratio hypothesis accounted for the observed validities rather well, but departmental discipline was not significantly related to the degree of fit of observed to implied validities. At all levels of selection, the study yielded applicant validities that were predominantly positive. This lends support to the presumption that the General Test's validity is transportable, i.e., institutions that do not use the General Test can, if they adopt it, expect it to prove valid. Appendices include: (1) use of test theory to present the effects of self selection; (2) use of a supplementary variable when data are missing for an explicit selector; (3) generalizing the assumption that the validities are proportional across institutions; and (4) calculating validities in the restricted group.
