Lexile and Quantile Measures in Connecticut 



Lexile® and Quantile® Measures in Connecticut

Students in Connecticut also may be receiving Lexile and Quantile measures from a variety of different tests and programs used by local schools. With Lexile and Quantile measures, educators and parents can 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 a student’s reading strength. Lexile text measures describe how difficult a text, such as a book or magazine article, is for a general reader. Lexile measures are expressed as numbers followed by an “L” (for example, 850L), and range from below 0L for texts that are appropriate for early fluent readers to above 1600L. 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.

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 the student likely already understands, and what the student is ready to learn in the future. The skill measure describes the difficulty, or demand, in learning the skill. Quantile measures are expressed as numbers followed by a “Q” (for example, 850Q) and range from emerging mathematician (below 0Q) to above 1600Q. The Quantile Framework spans the developmental continuum from the content typically taught in kindergarten, to Algebra II, Geometry, Trigonometry, and Pre-calculus. Quantile measures help educators and parents target instruction toward learning standards and the mathematical demands of college and careers.
