K-12 and expanded learning partnership are key to expanded learning program quality and increasing positive academic impacts of expanded learning participation. There are a variety of resources available to support such partnerships. The California After School Program Quality Self-Assessment Tool contains a section to assist expanded learning and K-12 practitioners/leaders to create plans for effective partnership. The National Association of Elementary School Principals resource Making the Most of After-School Time outlines successful case studies. Additionally, the Leadership for Student Success through After School Programs (LSSASP, also referred to as “the Principals project”) was developed to provide professional development, technical support and resources for district and school administrators as they address complimentary support for students between the core instructional day and expanded learning programs.
