Evidence-based intergenerational practices are sought by practitioners interested in the potential value of intergenerational programs. These are often difficult to identify as intergenerational program research frequently consists of small samples and pre-post analyses of attitudinal data with little attention to implementation characteristics. We systematically identified evidence-based intergenerational practices linked to program outcomes from peer-reviewed journal articles ( n = 21) published between 2000 and 2019. Scoping reviews facilitate synthesis of available evidence-based practices and identification of gaps in the literature. Fifteen evidence-based intergenerational practices were identified; each was coded in at least five articles. The practices informed program content (e.g., using technology), program considerations (e.g., environmental modifications), facilitator and participant preparation (e.g., training), and quality interactions among participants (e.g., incorporating mechanisms of friendship). While these identified practices reflect extant theory and research, rigorous implementation research is needed to advance evidence-based intergenerational practice as policymakers and practitioners advocate for intergenerational program growth.
