I'm thinking of sending my son to a private school when he starts kindergarten. Anyone have any data on how boys are doing in private vs public schools? I know there has been a real decline in boys achievement in public school, but I want to know if it will be worth the money to do this.

We only have a single non-religious private school in my area, so our options are pretty limited. Its a co-ed school with a huge majority of female teachers, but so are the public schools around here.
