This descriptive study explored the relationship between sustained attendance in high-quality 21st Century Community Learning Centers (CCLC)-- funded programs and key child outcomes. The key hypothesis was that high-quality programming is associated with the development of social and emotional skills, which in turn may be related to academic skills such as literacy. The study found that growth in five social and emotional skills measured by the Survey of Academic and Youth Outcomes the teacher version (SAYO-T)--self-regulation, perseverance, critical thinking, engagement in learning, and leadership--was greater for children who were enrolled in higher-quality programs, attended more regularly, or both. In turn, growth in these skills was significantly related to improvement in the number of words children could read on the Oral Reading Fluency (ORF) test.
