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 reader measure and the Lexile text measure. A Lexile reader measure represents a student’s reading ability on the Lexile scale. 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.

Today, Lexile measures are recognized as one of the most widely used reading metrics. Lexile measures connect learners of all ages with resources at the right level of challenge and monitor progress toward state and national learning standards. Lexile measures range from below 200L for beginning readers and text to above 1600L for advanced readers and text.

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

Find a Book Once students have their Lexile measures, they can search for titles matching their Lexile levels, interests and age appropriateness using the free Find a Book, North Carolina (fab.lexile.com/NC/) search tool. From there, students can build custom reading lists and check the availability of books at a local library or bookseller.
The Lexile PowerV® Vocabulary Tool 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 Titles Database® The database  contains Lexile measures for over 300,000 books from hundreds of publishers and is offered free of charge to educators.
Lexile Analyzer® The Lexile Analyzer measures the complexity of the text by breaking down the entire piece 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.   A Lexile measure should be used with other factors, like qualitative dimensions (purpose, structure, language conventions, knowledge demands) and reader and tasks considerations, to determine appropriateness of a text.
Lexile Growth Planner® Wondering if a student will be prepared for the reading requirements of college and the workplace upon graduation? The Lexile Growth Planner can provide some insight. With the Lexile Growth Planner, you can chart a student’s reading growth across different annual state assessments, forecast future reading growth, compare that forecasted reading growth with the text demands of college and careers, and, if needed, identify a custom growth path to ensure the student graduates college- and career-ready.
Lexile by Chapter Guides 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.
Lexile Measures at Home 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.
