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® 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 0L for beginning readers and text to above 1600L for advanced readers and text.

Using Lexile® Measures to Assess College and Career Readiness

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.
