Every year I have several students submit to some of these contests and every year I have at least one student that wins! Most of the prizes are publication or recognition, which is such an amazing success for students to feel. I encourage them to put "published poet" on their resumes and college forms :) Some of the contests even have prize money, so why not have them give it a shot? Check out Teen Ink, the National YoungArts Foundation, Poetic Power, and JustPoetry!! for starters.
