Quantile Research & Publications
Research Based. Research Driven.
At MetaMetrics®, everything we do is based on research.
More than 30 years ago, our founders, A. Jackson Stenner, Ph.D., and Malbert Smith, Ph. D., had a vision to make test scores more actionable by blurring the distinction between assessment and instruction.
They started with literacy. Supported by grants from the National Institute of Child Health and Human Development (NICHD) their research resulted in The Lexile® Framework for Reading. Today, it’s the most universal reading scale in the world, used by more than 35 million students in the United States alone.
What we’ve done for reading, we’re now doing for math. The Quantile® Framework for Math was developed with the same rigorous research mindset. To date, both the Lexile® and the Quantile® scales have been externally validated by more than 1,000 studies in 25 U.S. states and 24 countries. We’ll never stop the research. We want to ensure that our scales are accurate, relevant and effective.
