In the competitive marketplace of higher education, colleges and university leaders increasingly rely on the influence and service of their alumni to further institutional goals. Because of their demonstrated financial commitment to the institution, alumni donors are often enlisted to serve important roles as volunteers and political advocates. Using binomial logistic regression, this study examines a large sample of alumni donors from a large doctoral/research extensive university to predict donors who are most likely volunteer at the institution (via advisory board service, political advocacy, alumni club support). The study suggests that volunteering among alumni donors is predicted by capacity variables related to gender, residence, and overall civic engagement. Inclination to volunteer is associated with the quality of academic experience while an undergraduate student, beliefs about alumni volunteer roles, and number of degrees earned at the institution.
