The Lexile Framework for Reading is a scientific approach to measuring reading ability and the text demand of reading materials. The Lexile Framework involves a scale for measuring both reading ability of an individual and the text complexity of materials he or she encounters. The Lexile scale is like a thermometer, except rather than measuring temperature, the Lexile Framework measures a text’s complexity and a reader’s skill level.
Matching Readers with Text
The Lexile Framework assesses both sides of reading development— the reader and the material being read. The Lexile Framework reports a Lexile reader measure and a Lexile text measure. When a Lexile text measure matches a Lexile reader measure, a targeted reading experience can occur. The Lexile reader measure describes the reading ability of an individual. Over 65 popular reading assessments and programs report student reading ability as a Lexile measure. The Lexile text measure describes the semantic and syntactic features of a book, article or text. Over 100 million books, articles and websites have received Lexile text measures. Both Lexile reader measures and Lexile text measures are reported on the Lexile scale and are represented by a number followed by the letter “L” (i.e. 1000L).
