Having a graduation party for your high school or college graduate will be a lot of fun. You can have it at a public venue like a hall, park, or restaurant, or a private home. The theme will be, of course, Graduation, but you could have a sub theme like the colors of the school or even a luau party. Try sending out the invitations on scrolls like little diplomas and use calligraphy. You could decorate with balloons, streamers, and flowers. When they arrive, give each guest a plain white tee shirt and then have them sign each other's shirts as a keep sake. A fun activity might be to play pin the mustache on the teacher, or if it's warm outside, water balloon toss. Party favors will make great prizes and these could be graduation hats, fake diplomas etc. Food for teeners is easy as they will eat almost anything but finger foods work best like: hamburgers, hot dogs, pizza, chips and dips. Have a chocolate fountain and watch the fun or even a dessert island where guests can create their own extravagant desserts. Graduation cup cakes will be a favorite and top them off with chocolate scrolls or grad hats.
