AIPHS has higher scores than Preuss. But I guess if the weaker students at Preuss drop out, then their scores might be just as high as well. Preuss is also another good example of Charter school working.[/quote]
In my opinion, neither of them use a method that could scale to all public schools. The premise, stated or not, is that if you get enough students from disadvantaged situations to succeed, it would propagate out to the entire community.
