An increasingly important performance measure for university administrators is mean time to graduation at the department level. In this study, the authors examined whether a student's major is a significant variable in predicting time to graduate. If students in one major take much longer to graduate than do those in another major, administrators could make resource allocation decisions to address this issue. The authors propose a control chart as an appropriate statistical tool for identifying a major whose mean time to graduate is significantly different from the university average.
