What's this?Lexile Measures
A child’s grade level and reading ability are two different things. That’s why a Lexile® measures the child’s ability based on reading comprehension, not grade level. A Lexile measure (e.g., 850L) is the most widely adopted measure of reading ability and text difficulty. Lexile measures are valuable tools that help educators, parents and children select books that will provide the right level of challenge for the child’s reading ability—not too difficult to be frustrating, but difficult enough to encourage reading growth. The Lexile measure of a book is based on word frequency and sentence length, and is displayed on SimonandSchuster.com. The higher the Lexile measure, the more difficult the text is likely to comprehend, and vice-versa.
Please note: A Lexile measures text difficulty only. It does not address the subject matter or quality of the text, age-appropriateness of content, or the child’s interests. Parents are encouraged to preview all reading materials.

Guide to Lexile Codes
- AD: Adult Directed (book is generally intended to be read to a child, rather than for the child to read it for the first time independently)
- NC: Non-Conforming (books that have a Lexile measure markedly higher than is typical for the publisher’s intended audience or designated developmental level of the book)
- HL: High-Low (has a Lexile measure much lower than the average reading ability of the intended age range of its readers: “high-interest” plus “low-readability.”)
- IG: Illustrated Guide (books that consist of independent pieces or sections of text such as in an encyclopedia or glossary.)
- GN: Graphic Novel (book is a graphic novel or comic book)
- BR: Beginning Reading (A text that receives a Lexile measure of 0L or below is coded BR. The measure is shown only as BR, without the zero or negative number appearing. These books are appropriate for the emergent reader.)
- NP: Non-Prose (any book comprising more than 50% non-standard or non-conforming prose. Some common examples of non-prose content are poems, plays, songs, recipes, and text with non-standard or absent punctuation. Since the Lexile Framework is based on prose analysis, NP books do not receive a Lexile measure, merely the NP code.)
