The multiple and complex needs of the elderly require interdisciplinary collaboration among many different professionals to provide comprehensive care. As a result, educators must develop interdisciplinary programs and learning experiences that address educational needs and facilitate a better understanding of the various roles and expertise of providers from many fields. Using the framework of a program evaluation model, the Charting the Outcomes of Educational and Clinical Approaches model, this article addresses the outcomes and effects of an interdisciplinary approach to continuing gerontological education used by one summer institute on gerontology. Over its 12‐year history, this institute has attracted more than 2,600 participants from many professions and occupations. The interdisciplinary approach of the Summer Institute has been evident in its planning committees, the delivery of diversified programs by a variety of providers, the facilitation of informal networking among registrants, and the organization of group discussions that bring together professionals and learners from different disciplines to communicate and collaborate on mutual concerns regarding aging issues. One theme on case management, which addressed policy and practical issues related to service delivery for the elderly, was presented by representatives from academia, government, the nonprofit service sector, and consumers to an audience of providers from various fields including business, gerontology, health promotion, nursing, occupational therapy, psychology, recreation, social work, and sociology. Thesue cess of the interdisciplinary approach to gerontological education used by the institute has helped to establish McMaster University as a Canadian leader in this field of continuing education.
