Normative Data & RIT Scores
The most accurate norms
Today’s kids are vastly different than those in school ten years ago, so NWEA™ conducts norming studies frequently—every three years—ensuring that the comparisons reflect current standards and demographics. And we continually refine our best-in-class research model to make NWEA norms more accurate than any other—and always improving.
Norms Help Teachers Teach and Leaders Lead
Norms help you see if students are growing at an expected pace, regardless of where a student started. NWEA norms allow you to make predictions about what kind of growth is typical and atypical.
Student-level achievement norms
Help you see your students’ percentile rankings in a nationally representative student population.
Student-level growth norms
Allow you to compare your students’ growth with that of their academic peers.
How long is a MAP Growth test?
Tests are not timed, and students may take as much time as they need to complete them (this eliminates some of the pressure and anxiety students may feel about taking tests). Most students take less than an hour to complete a MAP Growth test. MAP Growth K-2 tests are typically shorter.
Provide a context for comparing grade level achievement and growth in a single school relative to other schools across the nation. MAP Growth is the only interim assessment that provides school-level norms, helping you compare specific grade levels in your schools to students in the same grade across the nation.
A Truly Representative Sample Pool
NWEA uses anonymous assessment data from over 10.2 million students to create national norms, placing your students and schools within a representative national sample. By drawing from an incredibly wide pool of anonymized test records (pulled from more than six million test events, 23,000 schools, and 49 states), we’re able to accurately represent the US school-age population.
Unlock a world of potential with RIT
MAP® Growth™ measures student performance with our RIT scale—the most stable, mature scale in the industry. Like centimeters on a ruler, it measures in equal intervals, regardless of a student’s grade or performance—and it remains stable over time. This gives you an accurate measure of student performance, regardless of whether they’re performing on, above, or below grade level.
Why our teachers use RIT scores
Teachers use a student’s RIT score to:
- zoom in on a student’s missing skills with MAP® Skills™
- connect to instructional resources aligned to student RIT scores
- track longitudinal growth over a student’s entire career
- group students for differentiated instruction based on RIT score ranges
- inform lesson planning based on what instructional areas student RIT scores reveal them to be ready to learn
- set growth goals with students

Get to know the RIT Scale
Students know exactly what their goal is. You’ll have a kid run up and say ‘I hit my goal!’ They’re into it. They understand it and they know they’re getting better.
