Social and Emotional Learning (SEL) has five competencies: relationship skills, responsible decision-making, self-awareness, social awareness, and self-management. A promising practice to promote positive SEL is school garden programming. There is a need to understand how school gardens impact SEL by consolidating existing research. In this scoping review, we synthesized evidence describing the impact of school gardens on youth SEL. We included studies that described school garden interventions, collected data from youth, and measured SEL. We screened 1589 abstracts and 76 full-text articles. Eight studies met the inclusion criteria. While the included qualitative studies demonstrated that school garden programming can positively influence SEL, the included quantitative studies had few statistically significant results. Thus, at this time we can only say that qualitative research from five studies suggests that school garden programs have the potential to successfully enhance experiences that promote SEL but more research is needed to further investigate this claim.
