The Quantile Framework® for Mathematics

The Quantile Framework for Mathematics (Quantiles.com) is a scientific approach to measuring mathematics achievement and the level of mathematical difficulty of skills and concepts.

The Quantile Framework consists of a Quantile measure and the Quantile scale. A Quantile measure represents the difficulty level of a mathematical skill, concept or application and a developing mathematician’s understanding of these mathematical skills and concepts in the areas of Geometry, Measurement, Number Sense, Numerical Operations, Algebra and Algebraic Thinking, Data Analysis, Statistics, and Probability. Quantile measures are expressed as numeric measures followed by a “Q” (for example, 850Q), and represent a position on the Quantile scale.

The Quantile Framework spans the developmental continuum from Kindergarten mathematics through the content typically taught in Math III, Algebra II, Geometry, Trigonometry, and Pre-calculus, from below 0Q (Emerging Mathematician) to above 1600Q.

Quantile measures take the guesswork out of determining which mathematical skills a developing mathematician has learned and which ones require additional instruction. They improve mathematics teaching and learning by targeting instruction and monitoring student growth toward proficiency standards and the mathematical demands of college and careers.


Benefits for Learners, Parents and Educators:

  • Benefits for Learners: Learn how a student’s Quantile measure can help parents better understand and communicate with their children’s teacher about which skills and concepts their children are ready to learn.

  • Benefits for Educators: Quantile measures empower educators in K-12 mathematics to prepare students for the introduction of new content. Learn how the Quantile Framework can help educators target instruction, track growth and identify appropriate resources.


Quantile Measures in North Carolina

Students in grades 3-8 and Math I receive a Quantile measure from the North Carolina READY End-of-Grade (EOG) Tests of Mathematics and NC READY End-of-Course (EOC) Assessment for Math I. Click here to view a score report sample containing Quantile measure information.

Additional mathematics tests and instructional programs have the ability to report students’ scores in terms of Quantile measures. Click here to access a list of assessments, by assessment type, which provide student Quantile measures.


Using Quantile Measures to Assess College and Career Readiness

The skills and concepts of the The Quantile Framework are aligned to the North Carolina Standard Course of Study based on the Common Core Standards for Mathematics (CCSSM). Two free Quantile web tools, Math Skills Database and the Quantile Teacher Assistant, allow you to search the database of Quantile skills aligned to North Carolina’s standards. Simply choose "North Carolina" from the drop down menu to access the alignment.  

Click here to learn how Quantile measures support the standards and how you can use them to help ensure college and career readiness.


Quantile Tools

More than 600 textbooks and 3,100 downloadable resources have been aligned to the Quantile Framework.

  • Math Skills Database: Search the Math Skills Database for skills and concepts aligned to your standards. The database contains targeted, free resources that appropriately match to students by Quantile measure and math content.

  • Quantile Teacher Assistant: Use the Quantile Teacher Assistant to differentiate math instruction by matching skills and their measures to the relevant standard you are teaching. This tool has been aligned with North Carolina’s mathematics curriculum standards.

  • Find Your Textbook: This free search tool helps educators, parents and students find targeted resources to supplement the textbook material. Users can search over 600 textbooks by title, ISBN, publisher, state edition or course.

  • Math@Home®: Math@Home provides access to a growing number of family-friendly mathematical resources that support the textbook lessons or math topics a child is studying in school.
