Objective: In this paper, we describe the implementation and outcomes of an initiative that engaged school-based health centers (SBHCs) in a learning community to create programmatic and policy school health changes beyond the health center walls. Methods: Sixty respondents completed impact surveys and 13 coalitions completed progress reports to document schoolwide wellness efforts and outcomes in stakeholder engagement, student healthy eating and active living, student social and emotional wellness, and school staff wellness. Results: Respondents reported pre- to post-intervention improvements in stakeholder engagement, including school administration promotion of school health policies (from 64% to 95%), and teacher participation in SBHC sponsored activities (from 63% to 98%). They reported schoolwide policy and programmatic achievements including increased opportunities for physical activity for students during school hours (from 55% to 85%), access to behavioral health counseling and support services to all students, either on-site or through referrals (from 62% to 89%), and offering healthy food or nutrition education to staff (from 10% to 73%). Conclusions: SBHC staff, school employees, and community members can work collaboratively to assess student physical and mental health needs, and develop and implement school policies and programs beyond the clinic walls.
