2011 RIT Scale Norms Study

The 2011 RIT Scale Norms Study was revised on January 17, 2012. For details, see page iii ("Document Revisions") in the Norms Study document.


The NWEA RIT Scale Norms grew out of the need for schools, districts, and other educational institutions to reference local student performance against a larger population of students. By describing how students from across the country performed when measured on NWEA assessments, partners have reasonable ways to compare a single student, a school, or the entire district to that of a much larger, meaningful group - a norm sample. The benefits of the latest study include the use of a stratified sample set that mirrors the ethnicity and socio-economic status proportions of the U.S. student population, includes grade K & 1 norms, and uses a model for growth norms that provides even more accurate long term growth projections.
