Here's a case in point of education redlining from Fairfax County, VA, one that's led to a complaint being filed with the U.S. Department of Education.
One of the county's most prestigious schools, Thomas Jefferson High School for Science and Technology, has a predominantly white student population. The Coalition of the Silence, an advocacy group led by former county School Board member Tina Hone, and the Fairfax chapter of the NAACP filed the civil rights complaint saying that the county's policies work to shut students of color out of schools like Thomas Jefferson. Specifically, a much smaller percentage of students of color in Fairfax County are identified as gifted and talented compared to their white peers, meaning fewer are given access to the advanced programs and resources necessary to prepare them for admission to prestigious schools.
'Giftedness' is independent of income and ethnicity. For any given population of students, there should be roughly the same percentage identified at gifted and talented and, thus, the same percentage participating in advanced courses and attending prestigious high schools. So by allowing this 'identification gap' to persist, Fairfax County is denying gifted students their rightful educational opportunities.
