The Lexile Framework for Reading places both the reader and text on the same developmental scale. A Lexile measure is a valuable piece of information about either an individual's reading ability or the difficulty of a text, like a book or magazine article.

Lexile Reader Measure

A student receives his or her Lexile reader measure from a reading test or program. MetaMetrics® does not offer a proprietary test that reports Lexile measures. 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. Every year, over 35 million Lexile reader measures are reported worldwide from more than 60 popular reading assessments and programs.

Lexile Text Measure

A book, article or piece of text receives a Lexile text measure when it's analyzed by MetaMetrics. We partner with over 200 publishing companies and have measured more than 150,000 books. We also partner with the nation’s largest periodical database service providers, including EBSCO, GALE and ProQuest, to provide Lexile measures for newspaper and magazine articles, as well as encyclopedia and reference content. Through these partnerships, more than 100 million articles and websites have received Lexile measures.

Matching Readers with Text

When used together, 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. You also can use Lexile measures to monitor a reader's growth in reading ability over time.
