These awards were set up in 1985 and they're one of the top book awards which are just for children.
The prizes go to a fiction book or poem written especially for children by an author who lives in the UK.
A panel of adult judges picks a shortlist of books in three age categories - under fives, six to eight years, and nine to 11s. Then every school in the country is asked to enter a competition to become final judges. 200 classes are picked and the kids in those classes decide who gets the gold, silver and bronze awards.
Last year the gold prizes went to Journey to the River Sea by Eva Ibbotson , The Shrimp by Emily Smith and Chimp and Zee by Catherine and Laurence Anholt.
Children voted the first Harry Potter book the top kid's novel in 1997, which helped catapult JK Rowling to fame and fortune!
