Student ratings of instruction: Validity and normative interpretations

Using 3,355 class section means, the relationship between six predictor variables and student ratings of instruction (CEQ) was investigated by computing the intercorrelation matrix among all variables and by performing several regression analyses. Results of the study indicated that all linear interactions were negligible and that more than one-fourth of the criterion variance was shared with all the predictor variables. Two predictor variables, expected grade and required-elective, provided extremely large contributions to the prediction of the criterion measure, however. Implications of the validity results with respect to normative data and thus to the administrative use of the ratings were illustrated.
