The Effects of Career and Technical Education: Evidence from the Connecticut Technical High School System

We examine the effect of admission to 16 stand-alone technical high schools within the Connecticut Technical High School System (CTHSS) on student educational and labor market outcomes. To identify the causal effect of admission on student outcomes, we exploit the fact that CTHSS utilizes a score-based admissions system and identify the effect of admission using a regression discontinuity approach. We find that male students attending one of the technical high schools are approximately 10 percentage points more likely to graduate from high school and 8 percentage points less likely to attend college, although there is some evidence that the negative effects on college attendance fade over time. We also find that male students attending a technical high school have quarterly earnings that are approximately 31% higher. Analyses of potential mechanisms behind these results reveal that male students that attend a technical high school have higher 9th grade attendance rates and higher 10th grade test scores. We find little evidence that attending a technical high school affects the educational or labor outcomes of women. These effects appear relatively broad based across different types of students in that we find little evidence of heterogeneity in these effects over student attributes like race and ethnicity, free lunch eligibility or residence in a poor, central city school district. However, when distinguishing between students based on the Career and Technical Education (CTE) offerings of the high school that these students likely would have attended, we find that the effects of admission to a CTHSS school are noticeably larger when the counterfactual high school has less CTE offerings.
