Here are a couple graphs that show the narrowing of the achievement gap since 1973. All the talk about the horrors of public schools, and teachers, and the rest is just manufactured hysteria. I am not saying that the gap is something we should be fine with; I have argued many times that we need to address the reasons for the gap because the gap is unacceptable. I have talked about ending poverty, and stuff like that. You know, stuff that could work, instead of finding a way to ruin public schools and teachers like we have apparently decided to do now.
