This dissertation investigates the impact of high school mathematics curricula on the TAKS exit-level performance of African American students, highlighting significant differences in performance based on course placement and scores in foundational subjects like algebra and geometry. The study involved quantitative analysis of test scores from 262 students and qualitative insights from 16 middle school counselors, revealing that those in higher track courses performed better and that counselors consider various factors like previous achievement and parental involvement in placement decisions. The findings suggest the need for improved support and placement strategies to enhance mathematics outcomes for African American students.
