Why would you say reducing accelerated classes could be a good thing? I had no such thing in school, but being bored had a huge part in school being hell for me. I read about schools for gifted children and dreamed about how cool it would be to be on such a school (not that I would necessarily have qualified, mind you). I am personally in favor of teachers having high expectations from pupils, that they can rise to meet.
