As the population of older adults increases, the field of adult education needs to respond accordingly. The study reported in this paper examined motivations for learning among older adults actively engaged in formal lifelong learning. One hundred eighty-nine members of a Learning in Retirement institute were surveyed using Boshier's Education Participation Scale. Cognitive interest appeared to be the strongest motivator for learning. Social contact was the second most influential motivator. The findings of this study are consistent with, and add to, our knowledge derived from previous studies pertaining to the participation of older adults in formal learning. Recommendations for future research on older adult learning in different settings are presented.
