This article examines the contribution of older adults as co-researchers to the evaluation of a gerontological social work course. The evaluation was conducted at an Israeli college as part of a collaborative project with a United Kingdom university. Here, we follow the older adults who are service users through their transition to the role of co-researchers and reflect on their experiences in the process. Insights gained by the different stakeholders from the co-researching experience are discussed, and the growing interest in service-user contributions to social work education in various fields such as aging and disabilities is recognized.
