The Lexile Framework for Reading

The Lexile? Framework for Reading is a unique resource for accurately matching readers with text. Unlike other measurement systems, the Lexile Framework evaluates reading ability based on actual assessments, rather than generalized age or grade levels. The true power of the Lexile Framework is its ability to measure both reading ability and text complexity on the same developmental scale. Other reading level formulas just measure text. It's like shopping for shoes and only knowing the sizes available. You need to know both the size of the shoe and the foot to have a good fit. The Lexile Framework is based on more than 20 years of research funded by the National Institute of Child Health and Human Development. Our distinct approach to measuring readers and texts has resulted in Lexile adoptions by departments of education in nearly half the states and school districts in all 50 states, and our global reach continues to expand. Tens of millions of students worldwide now receive a Lexile measure that helps them to find targeted text from a universe of over 400 million articles, books and websites. Barnes & Noble offers the ability to search for books by Lexile measure in stores and online. And the major test and text publishers provide Lexile measures. The Common Core State Standards for English/Language Arts cite Lexile measures as key indicators of text complexity. They provide recommended Lexile bands for reading comprehension development by grade levels to ensure students are on track for college and career text demands. Today, Lexile measures are recognized as the most widely used reading metrics. They are powerful tools for connecting learners of all ages with materials at the right level of challenge and monitoring their progress toward goals and standards.
