2011 Normative Data
Learn more about our latest study
NWEA has conducted RIT Scale Norms studies every three years from 1996, when the first study was produced. In 2011, several key aspects of the methodology were changed that dramatically improved the representativeness of the norming sample, including:
- Status and growth norms are now estimated from a single sample, enabling comparisons that reflect the distribution and demographics of students across each of the 50 states.
- The sample has been weighted against a School Challenge Index that better represents the actual characteristics of students and schools through 12 different school-level variables.
