This review presents an overview of selected articles on the leniency hypothesis: the idea that students give higher evaluations to instructors who grade more leniently. Such articles comprise a small subset of the voluminous research on student evaluations of teaching (SETs). In this diverse literature, research methods and aims have frequently…

It is incorrect to say "the test is reliable" because reliability is a function not only of the test itself, but of many factors. The present paper explains how different factors affect classical reliability estimates such as test-retest, interrater, internal consistency, and equivalent forms coefficients. Furthermore, the limits of classical test…

A measurement approach called generalizability theory (G-theory) is an important alternative to the more familiar classical measurement theory that yields less useful coefficients such as alpha or the KR-20 coefficient. G-theory is a theory about the dependability of behavioral measurements that allows the simultaneous estimation of multiple…
