Research is in our DNA. More than half of our team is comprised of psychometricians, data scientists and researchers who offer more than 600 years of combined experience. Our team holds more than 40 doctorate and graduate degrees from some of the most prestigious universities in the world, including Duke University, Princeton University, Stanford University and The University of North Carolina at Chapel Hill.

The vision for The Quantile® Framework for Mathematics was born from successful research that proved a universal scale for both assessment and instruction could accelerate math learning.

To date, MetaMetrics® scientific metrics, including Lexile and Quantile® measures, have been externally validated by hundreds of studies in 25 states and 24 countries, and we’re still exploring new ways to personalize learning based upon the principles of deliberate practice and sound psychometric theory. We continue to pursue research to help students and educators monitor and accelerate their track to success in college and careers.
