Lexile Measures are a tool used by teachers, parents, librarians and students to select books that provide the right level of difficulty for a student’s reading ability. If we determine how well a student reads and how hard a specific book is to comprehend, we are able to predict how well a student will understand the book. Finding books that are within a student’s comfort zone helps the student grow as a reader.
Lexile Measures are used to measure both a student’s reading ability and a book’s reading difficulty. By pairing a student’s Lexile Measure with a book’s Lexile Measure, students are able to find books that are challenging but not too easy or difficult. The student will have some level of difficulty with the book but not enough to get frustrated.
Lexile Measures are shown as a number followed by the letter “L”. The numbers range from 0L (beginner reader, or BR) to 2000L (advanced reader). The higher the number, the more skilled the student is at reading and the more difficult the text is to comprehend.
