I like small schools, but I also like middle-size schools. About ten years ago, Valerie Lee of the University of Michigan did a study in which she asked what was the ideal size for a high school, and she concluded that the ideal school was small enough for kids to be known by the teachers, but large enough to mount a reasonable curriculum. The best size for a high school, she decided, based on a review of student progress in schools of different sizes, is 600-900 students. You may think this is too large, but it sure beats schools of 2,000-3,000. I think we can all agree that the mega-schools that were created in the past forty years or so are hard, difficult environments for adolescents, where they can easily get lost in the crowd. Anonymity is not good for kids or for adults, either.
Anyway, American education seems to be engaged in yet another statistical sham, this time involving small high schools. Everyone wants Gates money, so almost every big-city school district is breaking up big schools into small schools. To make sure that they look good and get good press (the same thing), the leadership of some districts stack the deck by screening out the lowest performing kids—the special education students, the limited-English speakers, and kids with low test scores.
