The Lexile Framework® for Reading

The Lexile Framework for Reading (Lexile Framework) measures reading ability and text complexity on the same scale.

What is a Lexile measure?

There are two Lexile measures: the Lexile reader measure and the Lexile text measure. A Lexile reader measure represents a student’s reading ability on the Lexile scale, while a Lexile text measure represents a text’s difficulty level on the Lexile scale. Lexile measures are expressed as numeric measures followed by an “L” (for example, 850L), and represent a position on the Lexile scale. When used together, Lexile measures help a student choose a book or other reading material that is at an ideal difficulty to spur reading growth. Lexile measures range from below 0L for beginning readers and text to above 1600L for advanced readers and text.

Lexile measures help students of all ages better understand which books and other reading materials are at the right difficulty level. These measures help parents and schools more closely monitor students’ progress as they work toward meeting state and national learning standards.

College-and-Career Readiness Growth Planner

An important factor for college- and career-readiness is a student’s ability to read and understand texts of increasing complexity as he or she progresses through school. The Lexile Framework provides valuable insights into student readiness by measuring both the complexity of texts and a student’s ability to comprehend these texts.

Lexile Measures in Indiana

Each grade 3-8 student who completes the ILEARN English/Language Arts (ELA) assessment will receive a Lexile measure. Click here to view a score report sample containing Lexile measure information.

Indiana students, parents and educators can access INSPIRE. This database contains many of online newspaper and magazine articles to match a student’s Lexile range.

Please contact your child’s school to determine whether additional reading tests and instructional programs might be used in your child’s classroom to report a student Lexile measure. Click here to access a list of assessments, by assessment type, which provides student Lexile measures.

Lexile Tools and Resources

Once students have their Lexile measures, they can search for titles matching their Lexile levels and interests using the free Find a Book search tool at From there, students can build custom reading lists and check the availability of books at a local library or bookseller.

The Lexile Growth Planner can provide some insight as to whether a student will be prepared for the reading requirements of college and the workplace upon graduation. Schools can use the Lexile Growth Planner to chart a student’s reading growth across different annual state assessments, forecast future reading growth, and compare that forecasted reading growth with the text demands of college and careers. The Lexile Growth Planner can also be used to help identify a custom growth path to ensure the student graduates college- and career-ready, if needed.

The database contains Lexile measures for over 300,000 books from hundreds of publishers and is offered free of charge to educators.

The Lexile Analyzer measures the complexity of a text by breaking it down and studying its characteristics. The outcome is the text complexity, expressed as a Lexile measure, along with information on the word count, mean sentence length and mean log frequency.

This is a two-page overview of the benefits and usefulness of the Lexile Framework for Reading. It is also available as an ADA Accessible PDF.

This webpage details ways you can use a student's Lexile measure—and the Lexile measures of books and other reading materials—to foster literacy and learning at home.

The Lexile Map provides examples of popular books and sample texts on the Lexile scale ranging from 200L for beginning reader books to 1600L for more advanced texts. It's a quick reference guide that helps to show what a Lexile measure represents. The 11x17 Lexile Map is also available as an ADA accessible PDF.

The Lexile PowerV Vocabulary Tool identifies up to 10 challenging words in each book that are important for students to know. Parents and students can use the tool to identify words students might want to familiarize themselves with prior to reading a particular book.

Lexile by Chapter Guides explore the text complexity within a book by providing Lexile measures for every chapter in the text. Each guide includes a graph and table displaying the Lexile information to help educators, parents and students better understand where the peaks and valleys of complexity reside within a book.
