There are two kinds of 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, these 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. The Lexile reader measure can also be used to monitor a reader's growth in reading ability over time. Lexile helps readers grow, and helps parents and teachers know.
When a Lexile text measure matches or is in the range of a Lexile reader measure, this is called a targeted reading experience. The reader will encounter some level of difficulty with the text, but not enough to get frustrated. This is the best way to grow as a reader - reading text that's not too hard but not too easy.Click here to read more about what a Lexile measure is.
