Research

MetaMetrics® was founded more than 30 years ago as an educational research organization. Years of research formed the basis for the development of the Lexile and Quantile Frameworks, El Sistema Leer, and the numerous tools MetaMetrics provides for educators to use to make assessment results actionable and improve instruction. Our research continues today as we develop new frameworks and tools for educators.
