The Lexile Framework is a tool adopted by the Georgia Department of Education. Lexile measures appear on standardized tests results. A Lexile measure is a standard score that matches a student’s reading ability with difficulty of text material. The difficulty of the text is based on word frequency and sentence length. It is a book or article level that a student can read with 75% comprehension. A Lexile measure can range from below 200L for beginning readers to above 1700L for advanced readers. Readers who score at or below 0L receive a BR for Beginning Reader. Lexile measures help a reader find books and articles at an appropriate level of difficulty and determine how well that reader will likely comprehend a text.
