This study tracked college and workforce outcomes for students who began 8th grade in fall 1998 and attended a Texas public school. Students were tracked for 17 years, through summer 2015, when they were approximately 30 years old. Of the 38,322 eighth-grade students in Harris County, 30 percent finished a postsecondary certificate or degree. Female, white, Asian, and non-economically disadvantaged students were more likely to earn a postsecondary credential than male, black, Hispanic, and economically disadvantaged students.
