Lexile Text Measures
Overview and Introduction
“The Lexile® Framework for Reading is a scientific approach to reading and text measurement. There are two Lexile measures: the Lexile reader measure and the Lexile text measure. Students receive a Lexile reader measure as a score from a reading test – it describes his or her reading ability. Books and other texts receive a Lexile text measure from a software tool called the Lexile Analyzer – it describes the book’s reading demand or difficulty.
When used together, the Lexile measures can help match a reader with reading material that is at an appropriate difficulty, or help give an idea of how well a reader will comprehend a text. When a Lexile text measure matches or is in the range of a Lexile reader measure, this is called a targeted reading experience.”
Extensive information about the development of the Lexile Framework for Reading can be found in the Researchers section of the Lexile website.
