Lexile and Quantile Measures in North Carolina

The Lexile Framework® for Reading, commonly referred to as the Lexile Framework, has been linked to the North Carolina READY End-of-Grade (EOG) Tests of English Language Arts/Reading and the North Carolina READY End-of-Course (EOC) Assessment for English II. Similarly, the Quantile Framework for Mathematics has been linked to the North  Carolina READY End-of-Grade (EOG) Tests of Mathematics and NC READY Assessment End-of-Course (EOC) for Math I. The tests are administered each spring (and fall in high schools on the semester block schedule) to students statewide. The benefit to educators is that the Lexile and Quantile measures can be used to bridge assessment and instruction.

What is a Lexile measure?

There are two Lexile® measures: the Lexile reader measure and the Lexile text measure. A Lexile reader measure represents a person’s reading ability on the Lexile scale. A Lexile text measure represents a text’s difficulty level on the Lexile scale. When used together, Lexile measures help a reader choose a book or other reading material that is at an appropriate difficulty level and can predict how well a reader will likely comprehend a text at a specific Lexile level. For example, if a reader has a Lexile measure of 1000L, he will be forecasted to comprehend approximately 75 percent of a book with the same Lexile measure (1000L). The 75-percent comprehension rate is called “targeted” reading. 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 measures can forecast how well a reader will comprehend a text. Recognized as the standard for matching readers with texts, tens of millions of students worldwide receive a Lexile measure that helps them find targeted readings from more than 100 million articles, books and websites that have been measured.

What is a Quantile measure?

Similar to Lexile measures, there are two types of Quantile measures: a measure for students and a measure for mathematical skills and concepts.  The student measure describes what the student is capable of understanding.  The skill measure describes the difficulty, or demand, in learning that skill. Quantile measures improve mathematics teaching and learning by targeting instruction and monitoring student growth toward learning standards and the mathematical demands of college and careers.
