As the population ages, more older adults seek learning opportunities in various educational settings. This article highlights the understanding of older adult learners and the greater heterogeneity within this demographic. I explore why and how older adults learn, including their learning needs, the challenges of aging that may affect their learning, unique educational approaches designed for older adults--geragogy--and the application of geragogy. Finally, I conclude with the implications for supporting educators and practitioners in effectively navigating education for older adults across traditional and digital learning platforms.
