High School Shooting Legality?

So I have been starting to get a lot more into photography and I'm testing out a Smugmug Pro account right now. I would like to start making prints available for purchase, but I'm not sure on the legality. I'm in High School and most of my shots are of High School events; such as plays, sports games, and various other events. I've read about a model agreements here on the forums. Will I need one? My market isn't really going to be newspapers or anything but just the people involved in that activity. (Lead Actor, Linemen on the Football Team) Any help would be greatly appreciated. Thanks!

Talk to the school (likely the principal, athletic director, drama teacher), whoever is going to be in a position to protest you doing it is the one you want approval from. Work it out with them.

As far as federal and state laws are concerned in the US, you don't need a model release to take a picture of a person and sell that picture (to that person or to anyone else).

You would need a model release to use those pictures on a website to advertise your services as a photographer, and that release would have to be signed by the adult parent or guardian of the student. Also, the set designs for school plays are usually copyrighted by the producers of the plays, and that will prevent you from using those photographs to advertise your services. Promoting a product or service (even your own) is considered "commercial use," but selling the photograph itself is not commercial use.

However, your school or school district may have their own rules that prevent you from taking pictures at school activities if you intend to sell them for profit.

I totally read that wrong...raised my eyebrows a bit till I remembered we were photographers "High school shooting legality"
