- In the last 20th century experienced a slight trend toward increased Black-White segregation across schools.
- Segregation between school districts is the source of segregation between schools.
- White teachers are more likely to leave schools that serve a higher proportion of Black students, and these turnover rates increased dramatically over the late 1990s.
- Schools with higher percentage of Black students have lower quality resources (teachers).
- Results suggest that school segregation within districts more closely matched residential segregation in 2000 than in 1995.
- By 2000-01 students in predominantly Black schools had about 2 percentage points fewer certified teachers than students in schools in the other categories.
- White teachers are much more likely to leave schools that serve higher proportions of Black students, while there is no clear pattern for Black teachers.
