LGBTQ+, racial/ethnic minorities, youth from low-income contexts, and youth with cognitive and/or physical disabilities often face constraints to access and participation based on social and structural inequality. Understanding access and inclusion in summertime recreation program and camp settings for LGBTQ+, racial/ethnic minorities, individuals from low-income contexts, and individuals with disabilities begins with examining promising practices and policies already applied in some of these settings. The purpose of this study is to compile current promising practices implemented by youth-serving summertime recreation programs and camps recognized for their work in diversity, equity, inclusion, and racial justice (DEIRJ). Representatives from national organizations and more localized summertime programs and camps were interviewed to compile current promising practices. The results include general recommendations as well as recommendations aimed at populations of interest.
