Economic, health and social issues associated with the ageing population and the disconnect between the generations call for novel approaches to care services. Intergenerational programs are known to enhance engagement between generations, improve health and well-being and create a stronger sense of community. While the health and social benefits are well documented, little attention has been given to the operational aspects of intergenerational programs within care facilities. This paper describes the research protocol used to develop, implement and evaluate an intergenerational learning program for preschool-aged children and older people attending care services. The research focuses on five key areas: (a) impact on older people and children; (b) intergenerational learning; (c) workforce development; (d) socio-economic implications and costs; and (e) program fidelity and sustainability. Findings from this research are expected to contribute to building age-friendly communities through the development of practical operational guidelines for intergenerational learning programs to be implemented more broadly across Australia.
