Instructors often incorporate self- and peer evaluations when they use teamwork in their classes, which is common in management education. However, the process is often time consuming and frequently does not match well with guidance provided by the literature. We describe the development of a web-based instrument that efficiently collects and analyzes self- and peer-evaluation data. The instrument uses a behaviorally anchored rating scale to measure team-member contributions in five areas based on the team effectiveness literature. Three studies provide evidence for the validity of the new instrument. Implications for management education and areas for future research are discussed
