The purpose of this quantitative causal-comparative study was to examine the effect that Career and Technical Education (CTE) concentrators, non-CTE concentrators and academic concentrators have on the on-time graduation of 1035 high school students in 7 high schools in Arizona for the 2015--2016 school year. There were three research questions that drove this study: 1) What effect does CTE concentration and non-CTE concentration have on on-time graduation? 2) What effect does CTE concentration and academic concentration have on on-time graduation? And 3) What effect does non-CTE concentration and academic concentration have on on-time graduation? The theoretical foundation for this study was social cognitive theory with a focus on academic self-efficacy. The research questions were addressed using a chi-squared analysis and binary logistic regression (logit). The Chi-square test showed that there is a statistically significant association between CTE concentrators and on-time graduation chi 2 (1) = 0.15.893, p = 0.000. On-time graduation was not independent of CTE program completion for CTE concentrators and non-CTE concentrators, but on-time graduation was associated with program status. The binary logistic regression (logit), showed that CTE concentrators were 4.088 times, R[superscript 2] = 0.061, p = 0.000, and non-CTE concentrators were 1.907 times, R[superscript 2] = 0.015, p = 0.047, more likely to have higher on-time graduation over academic concentrators. These findings suggest that students who take or complete a CTE program will graduate on-time. [The dissertation citations contained here are published with the permission of ProQuest LLC.
