This study examined the dropout trajectories of racial and linguistic minority students and explored the effects of students' contextual factors on their high school dropout risks. Our motivation was to identify the dropout patterns of Black, Hispanic, and Hispanic English language learner (ELL) students, who have comparatively high dropout rates, and to suggest ways to promote high school completion. We employed a survival analysis using the National Longitudinal Survey of Youth 1997 (NLSY97) from the U.S. Bureau of Labor Statistics. The results showed that the 3 minority groups displayed significantly higher dropout risks than the White group. The overall pattern of dropout risks increased over time, with the dropout rates of the Black students high in the 1st and 2nd years of high school and the highest dropout rates for Hispanic ELL students in their senior year. A gender difference was found among the students, with male students having higher dropout risks than female students. It was also found that students' positive relationships with their teachers were associated with lower dropout risks.
