Teamwork is becoming more and more important in IS professions. A group project assignment is an effective method to train students' skills in teamwork. To reduce the free-rider problem and treat each group member fairly, the instructor needs to distinguish each individual's contribution to teamwork. In the paper, we analyze one commonly used peer-and-self assessment approach and point out its critical drawback: the deduced ranking might be wrong as some members do not tell the truth. Alternatively, we propose an effective mechanism to modify the peer-and-self assessment. The advantage of the revised peer-and-self assessment is that under the new mechanism, truth-telling is each individual's dominant strategy. Therefore, by using the revised peer-and-self assessment, the instructor can effectively distinguish each member's contribution to teamwork.

Keywords: peer-and-self assessment, teamwork, group project, game theory, mechanism design
