What is a Quantile?
A Quantile is the unit of measure on the Quantile scale. Quantiles measure student mathematical achievement and concept/application solvability similar to the way Lexiles measure reading ability and text difficulty. This measure is depicted with a simple number followed by the letter “Q” (as Lexiles are followed by an “L”). The Quantile Framework spans the developmental continuum from kindergarten mathematics through the content typically taught in Algebra II, Geometry, Trigonometry and Pre-calculus—from Emerging Mathematician (OQ and below) to above 1400 Quantiles. For example, a student with a Quantile measure of 500Q is likely to be ready for instruction of mathematics problems at a demand level of 500Q.
