As students search for experiential and career-oriented learning opportunities and employers seek to fill critical skills gaps in the workplace, more organizations in the US are turning to youth apprenticeship. Youth apprenticeship is an innovative work-based learning model supported by the work of intermediaries across the country. One such intermediary is CareerWise, a Colorado-based organization that supports businesses, students, and educators seeking to start programs employing young people as apprentices. The Urban Institute conducted a case study of CareerWise’s program to understand the impact of youth apprenticeship on employers and apprentices, and how CareerWise has worked to scale their model at the state level and beyond. CareerWise’s successes and challenges in developing their program can serve as useful lessons for advocates working to build youth apprenticeship across the country.
