garthsundem writes "According to Wired, test scores and student/teacher ratio are nearly meaningless. But three new numbers DO describe school quality:
1. (Test Scores/Parent Education): How do scores outpace expectations?.
2. Test Score Growth: Any single score can be socioeconomics, but *growth* is due to the school.
3. (Teacher Salary*%Highly Qualified/Teacher Age): The best teachers will become highly qualified early, and will gravitate toward the best paying jobs."
