What is a Lexile measure?

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 complexity. 

When used together, these measures can help match a reader with reading material that is at an appropriate level of 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. Reading targeted text can help readers grow, and using Lexile measures can help parents and teachers monitor progress toward state and national proficiency standards.

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. 

Lexile measures have been determined for hundreds of thousands of books. These titles and more can be found using the “Find a Book, Oklahoma” tool.

Parents are encouraged to use this free tool as a means to strengthen the home/school connection with the understanding that the Lexile measure does not reflect age-appropriateness, student interest, content, or the quality of the text. Reading material should always be previewed by parents or educators.

What can I do with my Lexile measure?

You can use it to easily find "just right" books either for school or for pleasure reading. The Lexile measure will let you know when a reader might need help or a little more challenge. 

Your Lexile measure is determined from a test, so try not to focus on the exact number. Instead, consider a reading range around the number. A student's Lexile range, or reading "sweet spot," is from 100L below to 50L above his or her reported measure. Use this range in our “Find a Book, Oklahoma”  tool to find books that match the student’s reading ability.

If a student tackles reading material above his or her Lexile range, consider what additional instruction or lower-level reading resources might help. Ask him or her to keep track of unknown words, and look them up together.
