As a few other people here have suggested, standardized test scores are a pretty narrow measure of education quality. Bill Gates mentioned that everyone in the room had probably had a few great teachers to get them to where they are now. When I think about the great teachers I have had, I certainly don't think they were great because they raised my standardized test scores. They were great because they gave me a much deeper understanding of a topic, or opened my eyes to something I hadn't seen before. Yes, the best teachers I had may have increased my standardized test scores some as a side effect, but it would be an insult to them if that's why I admired them so much as teachers. Test prep can be done in a factory, but not education.
