ABSTRACTThe study is framed by critical race theory to explore the intersection of cultural and institutional factors that influence Latino students’ completion of high school. The purpose of this study is to determine the extent to which factors related to students’ background, culture, socioeconomic status, and institutional-support such as participation in mentoring and/or dropout-prevention programs, can predict Latino students’ successful completion of high school. The overarching research question is: To what extent do family background, students’ educational aspirations, and institutional support programs predict whether Latino students’ complete high school? Using data from the Education Longitudinal Study of 2002 (ELS: 2002), from the National Center for Education Statistics (NCES) with 2,217 Hispanic participants, the study used a logistic linear regression model for the analysis. The findings identified students’ gender, socioeconomic status, first language, educational aspirations as well as the aspirations of their parents, school poverty concentration, and school support programs to be significant predictors of high school completion. The logistic regression model correctly classified between 78%, 85%, and 81% of the cases included in the group for timely completion according to first-, second-, and third-generation respectively. A similar classification was found for high school completion-within-two-years. The discussion highlights marked differences between the effect of dropout-prevention programs and that of mentoring programs on Latinos’ high school completion. In addition, that the factors represented by individual and institutional variables might not operate in isolation but instead might intersect with socioeconomic and cultural factors that ultimately create barriers for this minority group.
