Teaching in a K-8 or 6-12

While my impression is that Maine schools would not seriously consider a switch to a K-8/6-12 system for several years, it would effect my job in either system. I have yet to decide if I would be a high school or middle school teacher. It depends highly on my career choices in the next few years. If I decide to become a middle school teacher then my position would be highly effected by a process to move middle school students. If I were a high school teacher then it is less clear how my job would be effected by a k-8 system.
