Peer Evaluations: An Empirical Test of their Validity and Reliability

Abstract

This article reports an investigation of the reliability and validity of a peer evaluation method used to assign grades to students working on a client-sponsored class project. The 256 student subjects studied were undergraduate and graduate students and marketing and nonmarketing majors. The results suggest that the method described here provides an accurate measurement of how much effort a group member contributes to the completion of his or her group's project.
