During 2014-15, The School District of Philadelphia (SDP) offered CTE programs in 29 schools, across 37 professional tracks. This 49-page report examines the cohort of SDP students who were first-time 9th graders in 2011-12. These students’ four-year trajectories were tracked and analyzed with a focus on the effects of participation in CTE. In Part I, we update and replicate analyses that were conducted with a previous cohort. Part II identifies and analyzes factors that influence persistence within CTE.
