Community impacts of service-learning have gone largely unexamined by researchers, partly because of the absence of a well-established feedback tool. This study is a step toward filling this research gap by developing and validating the Community Impact Feedback Questionnaire (CIFQ) as a means for collecting feedback from partner organization representatives (PORs) on the impacts of particular service-learning projects on community partner organizations (CPOs) and, where applicable, end-beneficiaries. The CIFQ contains items about three categories of impact on CPOs, corresponding to a conceptual model developed by Snell & Lau (2022). These are: (1) achieving project goals to further the CPO's mission; (2) augmenting resources of the CPO; and (3) acquiring knowledge, insights, ideas, and techniques. There are also items on impacts for end-beneficiaries, overall impact evaluations, and future engagement. The CIFQ was validated with the Delphi method by inviting 16 practitioner panelists, mainly from CPOs, with prior involvement in service-learning. Three Delphi survey rounds helped refine the CIFQ as a tool for capturing the community impacts on CPOs and end beneficiaries arising from service-learning. Possible reasons for controversy and non-retention are discussed.
