For 20 years, Prime Time Palm Beach County, a nonprofit organization in Florida, has supported local out-of-school time programs with professional learning, capacity building, and other resources. One of the organization's most popular and longest-running professional learning offerings is called Bringing Yourself to Work, which helps out-of-school time practitioners develop self-awareness, understand and facilitate positive group dynamics, and strengthen their relationship-building strategies. Those are key social and emotional learning (SEL) skills that out-of-school time programs typically strive to foster in the young people they serve. Prime Time leaders believe these skills must be fostered in adults first. Prime Time and the School District of Palm Beach County aren't the only organizations focusing on professional learning to develop adults' SEL skills. That strategy is one of the themes emerging from a study of six communities working to foster SEL across school and out-of-school time settings. The Partnerships for Social and Emotional Learning Initiative, supported by The Wallace Foundation, is a six-year effort to prioritize social and emotional learning in Boston, Dallas, Denver, Palm Beach County, Tacoma, and Tulsa. The initiative focuses on simultaneously building capacity in schools and out-of-school time programs. Team members from two of the participating communities -- Palm Beach County, Florida, and Tulsa, Oklahoma -- spoke with "The Learning Professional" to share what they've learned during the first half of the grant period. Although they take slightly different approaches, both communities are committed to professional learning for adults as the backbone of improving practice and student outcomes.
