Recent updates to federal policy governing career and technical education (CTE) in the United States have emphasised the need to include work-based learning (WBL) experiences as central components of CTE programming. Many of these experiences showcase an informal learning component which has strong ties to early career success as suggested by the Human Capital Theory. This study explores the following questions: What is the relationship between WBL and early career income? Are there differential relationships based on the type of WBL experience? The Education Longitudinal Study of 2002 (ELS) includes nationally representative data for student participation in WBL and early career income. We used school-fixed effects and propensity score matching techniques to respond to our questions regarding the potential relationship between WBL participation and early career income. We found that students who participated in at least one WBL experience in high school could expect to have an average 7% higher income compared to non-WBL participants. With respect to specific WBL experiences, job shadowing, community service, and mentoring had the largest positive relationship to higher early career income. Findings from this study indicate that participation in WBL experiences can have a positive impact on a high school graduate's college and career readiness as measured through early career income. Given the differential relationships observed for different types of WBL, schools, policymakers, and students should explore WBL options that best align with their personal goals.
