Determining the Age Group for Children's Books - video

The reading level in children's books is important for a book's market. It determines the approximate age of your target audience. Jennifer Emmett, vice president and editorial director of children's books for National Geographic Books, describes what factors weigh into determining the age group for children's books. She explains that they look at the complexity of the material, how the book pairs up with what is being studied in schools, and the level of writing. Vocabulary and sentence structure also play a role in determining the reading level.
