Lexile® and Quantile® Measures in North Carolina

The Lexile Framework® for Reading, commonly referred to as the Lexile Framework, has been linked with the North Carolina End-of-Grade Assessment in English Language Arts in grades 3–8 and North Carolina End-of-Course in English II. Similarly, The Quantile Framework® for Mathematics will be linked to Edition 5 of the North Carolina End-of-Grade mathematics assessments in grades 3–8 and North Carolina End-of-Course in Math 1 and Math 3. Students in North Carolina also may be receiving Lexile and Quantile measures from a variety of different tests and programs used by their local schools. With Lexile and Quantile measures, educators and parents can spur and support student learning.

What is a Lexile® measure?

There are two kinds of Lexile measures: Lexile reader measures and Lexile text measures. Lexile reader measures describe how strong of a reader a student is. Lexile text measures describe how difficult, or complex, a text like a book or magazine article is. These two measures can be used together to match a student with texts of best fit. Lexile measures are expressed as numeric measures followed by an “L” (for example, 850L), and represent a position on the Lexile scale. Comparing a student’s Lexile measure with the Lexile measure of what they are reading helps gauge the “fit” between a student’s ability and the difficulty of text. A Lexile measure should be used with other factors, like qualitative dimensions (purpose, structure, language conventions, knowledge demands) and reader and tasks considerations, to determine appropriateness of a text.

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 mathematics skills and concepts the student likely already understands and what the student is likely ready to learn in the future. The skill measure describes the difficulty, or demand, in learning a skill. Quantile measures are expressed as numeric measures followed by a “Q” and ranges from Emerging Mathematician (below 0Q) to above 1600Q. Quantile measures help educators and parents target instruction and monitor student growth toward learning standards and the mathematical demands of college and careers.
