Also, I see a problem in the president using the achievement gap as a measure of schools in his suggested revisions. This could mean that a wonderfully diverse school like T.C. Williams High in Alexandria, a recent subject on this blog, would be motivated to ignore its best students, who want to get even better, and focus all its money and time on those at the bottom of the achievement scale so they can narrow the gap. That is not a good idea, and I hope the president will get it out of his proposal.
