The Lexile® Framework for Reading, commonly referred to as the Lexile Framework, has been linked with the SC READY ELA assessment for grades 3-8 and the EOCEP English 2 assessment. Similarly, the Quantile® Framework for Mathematics has been linked with the SC READY math assessment in grade 3-8 and the Algebra 1 EOCEP assessment. Students in South Carolina are also 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 reading measures and Lexile text measures. Lexile reading measures describe a student’s reading comprehension ability. Lexile text measures describe the difficulty, or complexity, of a text like a book or magazine article. Lexile measures are expressed as numbers followed by an “L” (for example, 850L), and range from below 0L for beginning readers and text (for example BR100L) to above 1600L for advanced readers and text. 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 the text. Therefore, connecting students with books in their Lexile range – 100L below to 50L above their reported Lexile measure – provides an ideal level of reading challenge.
What Is a Quantile Measure?
Similar to Lexile measures, there are two types of Quantile measures: a measure that represents students’ math abilities 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, of learning the skill. Quantile measures are expressed as numbers followed by a “Q” (for example, 850Q) and range from emerging mathematician (EM - 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 and monitor student growth toward learning standards and the mathematical demands of college and careers.
