Lexile Measure

Please note that the Lexile measures for a small population of books have been recently updated. Enhancements were made to more precisely measure materials read in K-2 classrooms. Although the vast majority of books that have Lexile measures did not change, a small subset of books required updated Lexile measures.

Many products and services offer Lexile measures for their books and reading materials. We are working with the hundreds of companies that partner with us to transition them to the more precise Lexile measures.
