Generalization of GRE General Test Validity Across Departments

- Hypothesis 1: “validities for a measure were the same for all institutions”
- Hypothesis 2: “although the validities were not the same for all institutions, the ratios of the scores’ validities (verbal to quantitative and quantitative to analytical) were the same”

Generalization of GRE General Test Validity Across Departments - Hypotheses

Boldt (1986) examined GRE validity across graduate-school disciplines using three groups: all test takers, graduate-school applicants, and admitted students. The study reported no validity differences attributable to discipline and characterized GRE validity as context-specific and highly susceptible to sampling variation.

Literature on Generalizability and Validity of GRE

Researchers studied the validity of the GRE by determining the relationship between different test sections and psychometric characteristics on the 4 chosen populations and the convergent and discriminant validity of each section. Each of the 3 sections (verbal, quantitative, analytical ability) were further divided based on question type into a total 10 subsections. Maximum likelihood (MLH) estimates were used to find invariant variance-covariance matrices for the relationships between question type and abilities.
