I just left a comment as a reply to this post because that statistic intrigued me. I had to go hunting for the actual paper, and when I finally found it it seems to suggest that discrepancy is because the study lumped students who have access to gifted programs with students that don't have access. Additionally it identified that 83% of black students had access to a gifted program as opposed to 91% or something of white students. Additionally the study cited says that they had several gaps in their data and used some statistical regressions to fill in those gaps. All this leads me to believe that we need to provide more access to gifted programs, and the problem isn't that we have a herd of racist teachers on the loose.
