I'll have to find out more.Unless there's some specific reason, but it's not a gender studies class, and not sure what it would have to do with shadowing a diplomat. Surely there's a bit more to it kickazz ?
I'm thinking what must be the case is that it is not the school's policy so much, but some other organisation specialises in providing this opportunity for girls, and that organisation has offered it's services to the school?
Still not ideal but I can't see how a school would get away with making that rule.
