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.

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.

The Lexile® Framework for Writing is an innovative tool for differentiating writing instruction and monitoring growth in writing ability. It expresses student writing ability on the same Lexile® scale as reading ability, providing an easy-to-understand language for expressing student writing growth and reinforcing the importance of reading in the development of writing skills. A Lexile writer measure is an estimate of a student’s ability to express language in writing based on factors related to semantic complexity (the level of the words used) and syntactic sophistication (how the words are combined into sentences). Like Lexile reader measures, Lexile writer measures were designed to monitor writing progress within and across school years.
