From their beginning, community schools have expanded the learning day as a central component of their comprehensive strategy. Community schools of the early twentieth century served as centers of the community where students, families, and community members came to learn, to become civically engaged, and to prepare for the workforce. In this way, community schools served as a precursor to current efforts to expand learning time and opportunities in schools. Today, community schools and their partners continue to expand learning time and opportunities as one important dimension of a comprehensive strategy to ensure that students are ready for college, career, and citizenship, and to strengthen families and the community. In this article, the authors describe community schools, lay out the similarities and differences between the community schools and the ELT schools, and provide examples of how community schools are expanding both learning time and opportunities. Finally, the authors present a set of principles for using expanded learning in a community school setting. (Contains 21 notes.)
