The Lexile® Framework for Reading

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

What is a Lexile® measure?

There are two Lexile measures: the Lexile reading measure and the Lexile text measure. A Lexile reading 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 early 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.

Check out the graphic below for an example on using Lexile measures:


Understanding Lexiles

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 sample score report containing Lexile measure information.

In addition to using many free resources from MetaMetrics, Indiana students, parents and educators may also access INSPIRE from the Indiana State Library. INSPIRE is a free, online database containing many online newspaper and magazine articles to match a given student’s Lexile range.

Please contact your child’s teacher to determine whether additional reading tests and instructional programs used in your child’s classroom report a Lexile measure. Parents and educators can also access this list of assessments, which references the assessment type and whether each provides Lexile measures.

Lexile Tools and Resources

The Lexile® and Quantile® Hub

The Hub platform provides access to all of the Lexile and Quantile tools that support student learning and growth in reading and math. Read tool descriptions below or visit the Hub at to access all tools.

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

The Lexile Analyzer® measures the complexity of a text by breaking it down and studying its characteristics. The Lexile measure helps parents and schools understand the difficulty level of a text, the number of words in the text, and the average length sentences in the text.

Schools can use the Lexile® Growth Planner to chart a student’s reading growth across different annual state assessments. They can use this tool to help predict future reading growth and compare that predicted reading growth with the kind of text students will encounter in 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.

Create your own customized lists of consequential words using Lexile® WordLists. This online collection of 40 million words is based on general and academic domain K-12 vocabulary. Lists can be downloaded and printed.

Identify the Lexile level associated with the reading demands of a particular career using the Lexile® Career Database.

Explore the Lexiles® Measures Manager to determine a student's optimal reading measure when two assessments have resulted in significantly differing Lexile measures.

This six-minute animated video on the basic concepts and uses of the Lexile Framework for Reading is a recommended resource for educators and parents who are new to Lexile measures.

Educators and parents can review the Lexile® Infographic to learn more about the Lexile measure and how it can be used.

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.

This two-page overview outlines the benefits and usefulness of the Lexile Framework for Reading.

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