Lexile measures are easy to find. With more than half of U.S. students receiving Lexile measures, and more than 100 million books, articles and websites having Lexile text measures, they are the most ubiquitous reading metric in the country and around the world.

To match students with text, you need to find two types of Lexile measures: Lexile reader measures and Lexile text measures. With both of these measures, you and your child’s teachers can easily connect them with just-right reading materials, accelerating their reading development and helping them navigate the path to success in school, college and career.

Lexile Reader Measures

Students receive a Lexile reader measure from a reading test or program. There isn’t a special “Lexile” test. Instead, we partner with state departments of education and test publishers to create assessments, or link to existing assessments that can report students’ reading scores as Lexile measures.

If you haven’t seen your child’s Lexile measure, look at their latest standardized test results or ask their teacher. There’s a good chance that your child has received one or more Lexile reader measures. More than 35 million students in all 50 states receive Lexile measures, and more than 65 popular reading assessments and programs and 25 state assessments report Lexile measures. Browse products that report Lexile reader measures.

Lexile Text Measures

It’s also simple for parents and educators to find reading materials with Lexile text measures. Today more than 100 million books, articles and websites display Lexile measures on their reading materials.

A book, article or piece of text receives a Lexile text measure when it’s analyzed by our algorithm that evaluates text complexity. We partner with more than 200 publishing companies and have measured nearly 300,000 books and counting. We also partner with the nation’s largest periodical database service providers, such as EBSCO, GALE and ProQuest, to provide Lexile measures for newspaper and magazine articles, as well as encyclopedia and reference content. See the publishers and products that provide Lexile text measures.

If you don’t see a Lexile text measure printed on a book, you can often find them by using our Lexile® Find a Book tool. You can also use Find a Book to search for books that match your child’s interests and are within your child’s Lexile reading range.
