The Lexile® Framework for Reading

The Lexile® Framework for Reading measures reading ability and text complexity on the same developmental scale. Today Lexile® measures are recognized in the United States and around the world as the standard for matching readers with texts, over 35 million U.S. students from all 50 states — more than half of the country’s K–12 students — receive Lexile measures every year. More than 65 popular reading assessments and programs and half of all state assessments report Lexile measures. And when a student has a Lexile measure, they can be matched with the more than 100 million articles, books and websites that have Lexile text measures, putting them on the path to success in school, college and careers.

Like its English-language counterpart, El Sistema Lexile® para Leer provides its own developmental scale and measures to connect Spanish-speaking readers with resources at the right level of difficulty and in their native language. Spanish Lexile measures help educators, librarians and parents select targeted materials and activities that can improve reading ability and monitor reading growth in school, the library and at home.
