What are Leveled Readers?

Leveled Readers are books that have been evaluated against a series of established criteria by early literacy specialists. The books are organized into 29 developmentally appropriate levels from easy books for aspiring readers to longer, complex books that a fluent reader would choose. Leveled books develop reading comprehension, fluency, phonics, and vocabulary. They are available in both fiction and nonfiction, and on a variety of topics appealing to children of every age.

Books are assigned a guided reading level based on several factors:

  • Genre
  • Vocabulary
  • Illustrations
  • Sentence complexity
  • Content
  • Theme
  • Text structure
