Using predictive validity studies of the Law School Admissions Test (LSAT) and the undergraduate grade-point average (UGPA), this study examined the large variation in the magnitude of the validity coefficients across schools. LSAT standard deviation and correlation between LSAT and UGPA accounted for 58.5 percent of the variability. (Author/EGS)

Test bias, assumed as equal regression lines between two different tests for different populations was investigated to predict Metropolitan Achievement Tests from the Wechsler Intelligence Scale for Children--Revised. Subjects were 1,040 children in grades 1, 3, 5, 7, and 9: Anglo American, Black, Mexican American, and Native American Papago. (JKS)

A new measure of academic performance was developed through a new application of item response theory (IRT). This new criterion, an IRT-based grade point average (GPA), was used to determine the predictive validity of certain preadmissions measures for 1,564 students admitted to Stanford University in 1982.

Item response theory (IRT) is used to develop a form of adjusted cumulative grade point average (GPA) for use in predicting college academic performance appropriately for males and females. For 1,564 students at Stanford University (California), the IRT-based GPA was more predictable from preadmission measures than the cumulative GPA. (SLD)

The assessment framework underlying a science performance monitoring program is process-oriented and intended to appeal to generalizability theory for a suitable estimation paradigm. Preliminary applications are described. Results suggest that computerized question-banking, domain-sampling of questions, and generalizablity theory together provide…
