The purpose of this Policy Impact Snapshot is to identify the major categories of career and technical education (CTE) currently available within our nation's secondary and postsecondary education systems and describe the existing research on whether these programs are achieving desired outcomes for students. This Policy Impact Snapshot describes four major types of CTE programs: (1) CTE instruction and training; (2) Career Pathways; (3) Youth Apprenticeships; and (4) Career Readiness and Skills Training. The evidence of effectiveness for each category was reviewed and it was found that, because CTE programs have been around for so long, there are many studies, including many that are out of date. Many also describe associations and relationships rather than causal connections to specific outcomes. But over time, better data availability and quality have allowed researchers to conduct more rigorous studies. In this paper, the focus is on those more recent and rigorous studies.
