Are you writing a children’s book -- nonfiction or fiction? Here are a few tips on how to test your almost final draft. And test your manuscript on the same audience that is going to read the book. Make them junior editors. 1. Talk with a teacher at your local school that has a classroom of your book’s age group. Ask for permission to come in and read the book to the class. Video tape the children’s reactions or ask two people to accompany you to record the children’s reactions to direct part.
