Lexile Framework® for Reading
evaluates reading ability and text complexity on the same developmental scale. Unlike other measurement systems, the Lexile Framework determines reading ability based on actual assessments, rather than generalized age or grade levels.
Lexile measures match learners with text, providing an ecosystem for building reading comprehension skills. With Lexile measures, educators and families have a powerful tool for supporting learners as they navigate the path to academic success in reading.
Recognized as the standard for matching learners with texts, more than 35 million students in all 50 U.S. states and from 180 countries around the world receive a Lexile measure that connects them with targeted readings from the more than 100 million articles, books and websites that have been measured. Today more than 65 popular reading assessments and programs and 25 state assessments report Lexile measures. For more information about the Lexile Framework, visit Lexile.com.
