Tippins et al. (Reference Tippins, Hakel, Grabow, Kolmstetter, Moses, Oliver and Scontrino2023) illustrate the importance of experienced industrial-organizational (I-O) psychologists volunteering their expertise to benefit nonprofit and charitable organizations in numerous ways. Yet, we propose that engaging more inexperienced members of the Society for Industrial and Organizational Psychology (SIOP) and I-O psychology community, specifically graduate students, in volunteer efforts is necessary to further contribute to our field. Encouraging volunteerism within this overlooked population can expand our community’s influence upon the health and effectiveness of nonprofit organizations while simultaneously serving as training for future I-O psychologists. Furthermore, fostering a desire to serve within our community during the formative years of graduate school is critical to developing a sustainable model of volunteerism. In this commentary, we highlight a specific program—the Volunteer Program Assessment (or VPA; pronounced vee-pah)—that has engaged graduate students in meaningful volunteer consulting efforts for 15 years. Approximately 230 graduate students have served as VPA consultants in that time, totaling a collective impact of 787 VPA surveys administered to volunteer programs. We extend the arguments from Tippins et al., to show how applying I-O knowledge and skills by volunteering during graduate school, through programs such as VPA, enhances graduate student education through the development of professional skills, training skills, and networking opportunities. To promote the continued mobilization of volunteerism among graduate students, we provide information on how other graduate programs and professional organizations can initiate these efforts.
