The Reconnecting Youth project aims to systematically understand what programs and practices are available in the United States to support young people who experience disconnection from school and work during the transition period to adulthood (typically defined as ages 16 to 24). It focuses specifically on services to help them reconnect to education, obtain employment, and advance in the labor market. This population of young people is often referred to as "disconnected youth" or "opportunity youth." This project has produced two online tools to support these goals. The first is a compendium of programs, the focus of this publication, which provides an overview of 78 programs and the practices they employ. The second is an evidence gap map that looks at the available evidence about these practices to identify what evidence exists and where there are opportunities to build evidence. The study team from MDRC and Child Trends conducted an expansive search to identify programs that met the scope of the compendium and fielded a qualitative questionnaire to all programs from the search. The 78 programs in the compendium together were projected to serve nearly 100,000 young people in 2021. This overview provides high-level findings from the questionnaire and connects these results to findings from the evidence gap map. The findings offer insights into what services and implementation practices are more common or less common, the use of innovative practices, and the breadth of activities programs undertake in support of young people.
