The Lexile Framework was developed by MetaMetrics®, an educational measurement and research organization based in Durham, N.C. Lexile measures will be linked with the results of the Kentucky reading assessments and are available for teachers, students and parents.
The Lexile Framework is a resource for matching readers with text. It measures a student’s reading ability based on actual assessments, rather than a generalized age or grade level. Lexile measures allow teachers, librarians and families to find books, articles and other materials that will challenge a student’s reading ability, while still maintaining interest and learning. Recognized as the most widely adopted reading metric, more than 30 million Lexile measures are reported annually from reading assessments and programs, representing over half of U.S. students. A Lexile measure can range from below 200L for beginning readers and beginning-reading text to above 1700L for advanced readers and text. A book, article or other text gets a Lexile measure when it's analyzed by MetaMetrics. A Lexile text measure is based on two strong predictors of how difficult the text is to comprehend: word frequency and sentence length.
Teachers, parents and students may access the free “Find a Book, Kentucky” search tool to look up the Lexile measure of a book and to build custom reading lists that match a student’s reading level and needs, and then locate their selections at the local library. In many school and public libraries, Lexile measures are included in their catalog systems, although libraries are not required to label books with Lexile measures.
MetaMetrics, an educational measurement and research organization, develops scientific measures of student achievement that link assessment with targeted instruction to improve learning. The organization created the widely adopted Lexile Framework for Reading (www.Lexile.com), El Sistema Lexile para Leer, (the Spanish-language version of the reading framework) and The Lexile Framework for Writing.
