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.
