The document presents norms data from NWEA MAP tests in reading, math, language usage, general science, and science concepts. The norms are based on a study of over 5 million K-11 students from over 13,000 schools. The norms provide average RIT scores at the beginning, middle and end of year for each grade level tested, to measure student growth and achievement compared to national averages. The flexible norms framework allows comparison of student performance relative to instructional time periods and between schools with similar characteristics.
