This study profiles two high schools with high enrollments of low-income and racial/ethnic minority students: Thornton Fractional North High School (TF North) and Dumas High School (DHS). Both schools have substantial enrollments of low-income and racial/ethnic minority students and, despite the odds, are successfully preparing students for their post-high school goals. The researchers' purpose was to identify the policies and practices that appear to be contributing to the schools' success. Such information can help teachers, administrators, and other stakeholders who are seeking to improve the academic preparation of their students, particularly those in high-poverty and high-minority schools. Appended are: (1) Thornton Fractional North High School Profile; and (2) Dumas High School Profile. (Contains 5 notes.)
