Public v. Private
I've been digging through SAT scores for Washington's students, and I find the comparison between public and private school mean scores interesting. For 2004:
Of course, there are far fewer private school students in the pool (2,508) compared to public school students (27,467), but maybe that's a good argument for increasing one pool and decreasing the other. Maybe it's a good argument for allowing parents to send their children to the best schools they can think of using some or all of the $9,688 per-student we're currently spending every year on public schools.
