Since 1998, the Hartford Partnership Program in Aging Education (HPPAE) has been implemented in over 70 graduate social work programs. This study examined whether program and individual student characteristics are associated with students' knowledge, skills, and values in aging. We conducted a secondary analysis of national program evaluation data. Results from hierarchical linear models indicated greater gains in knowledge of aging among full-time students, as well as students in programs that had defined field rotation models and/or that made greater use of geriatric social work competencies. Implications for efforts to enhance graduate social work education in aging are discussed.
