It also explores the range of OST programs and activities as employed by the various youth-serving sectors; considers the untapped possibilities of OST programs to meet the needs of young people, including academic enhancement, career and college preparation, leadership development, and civic engagement; and provides policy guidance on how to support and sustain high quality OST programs as part of a system of supports for older youth. This paper is organized into the following parts: (1) Research on Out-of-School Time Programming for Youth: A Literature Review; (2) Emerging Practices and Partnerships to Create Quality Out-of-School Time Programs for Older Youth; and (3) Recommendations.
