Building on prior research documenting associations between youth purpose and academic, psychological and physical well-being, this study examined the contributions of workplace learning (WPL) to youth purpose and internal motivation among 281 youth of diverse racial and ethnic identities and economic status enrolled in two high school networks offering innovatively designed WPL. Sequential regression analyses revealed that the quality of WPL, defined by mentor support for training, learning opportunities, and youth autonomy, contributed positively to youth purpose and internal motivation, beyond the negative effects of perceived social and economic barriers. Findings are discussed through the perspectives of psychology of working, decent education, self-determination theory and career construction and suggest that WPL is a promising intervention for overcoming inequities in fostering youth talent and purpose, including personal goals, meaning and intentions for social contribution.
