Not sure what you mean by centralized school management. But for me (and of course I know you will disagree and I don't want to get into it) the biggest problem with the school system is that it is run by liberals. They fight accountability at every turn. Just look at no "child left behind" and Voucher programs. Ok that's my dig for today. Feel free to respond but I will not debate politics here further. You can have the last word on this.
