Our best-in-class scale delivers results educators trust
After every Measures of Academic Progress® (MAP®) interim assessment, each student receives a score that helps illuminate what he or she knows, is ready to learn, and is projected to achieve. And thanks to something no other interim assessment offers—a mature, reliable, and stable scale—you can trust that the scores you see are both accurate and fair. Our scale, the RIT (Rasch Unit) scale, is a stable equal-interval vertical scale. You can compare the performance of your students and school/district relative to:
- national achievement and growth norms
- state standards, including the Common Core State Standards (CCSS)
Take the next step
MAP assessments use the RIT scale to create a grade-independent RIT score, which indicates the level of question difficulty a given student is capable of answering correctly about 50% of the time. RIT scores help educators understand every student’s current achievement level based on their zone of proximal development.
RIT Scale Overview
How the RIT scale and robust national norms support efforts to boost every student’s learning and growth
Allow seamless measuring and monitoring of K – 12 student growth term-to-term and year-over-year, a feature no other interim assessment provides
Support the rigor and strength of MAP assessments and includes valid, reliable assessment data from more than 35 million students
Ensure educators have accurate information for differentiating instruction
Produce a precise measurement of a student’s achievement that can be used to project proficiency on state standards via NWEA linking studies
Provide linking study data that accurately projects college readiness for students in grades 5+ (as measured by ACT® benchmarks)
Permit creation of norms based on a nationally representative sample of MAP test scores
From a single classroom to the entire nation, compare and contrast student and school performance
Providing norms based on a nationally representative sample of MAP test scores from over 10 million students
At NWEA™, we conduct regular norming studies that allow us to estimate growth based on each student’s starting position on the RIT scale and the amount of instructional time offered. The 2015 NWEA norming study includes students whose districts or states have adopted and implemented the Common Core as well as those who have not. And this year, it also provides MAP status and growth norms for schools as well as students.
See a student’s percentile ranking in a nationally representative student population.
Compare a student’s growth to that of his/her academic peers.
Monitor school performance over time and compare specific grade levels across schools or the nation.
Discover how we use data related to school characteristics (including district locale, proportions of ethnicities, and Title 1 status) to create nationally representative samples for each subject area.
How do you accurately measure student growth in transitional times?
MAP K – 12 computer adaptive interim assessments deliver key insights into all your students’ instructional needs, including high- and low-performing students, special needs students, and early learners. You’ll also receive growth and norms data that permit you to evaluate student achievement independent of grade, over time, and in relation to students across the U.S.

Aiding classroom instruction by providing comparative data
MAP RIT scores help you make informed decisions about the programs or strategies that help your students learn. We offer comparative data for each MAP assessment that breaks down RIT scores.
Supporting educators who use MAP outside the U.S.
International schools and organizations that use MAP assessments have their own set of comparisons. They can: use international comparisons, gauge international students’ performance, and use growth data to compare international students’ rate of growth and/or set goals
Getting the context you need to maximize student learning
How are you tracking your students’ progress on new, rigorous state standards—including each student’s learning challenges and triumphs? Learn why the three kinds of data comparability (horizontal, vertical, and longitudinal) offer important context as you strive to accelerate student learning, monitor progress toward proficiency, and see how your students’ achievement compares to those within your district and across the nation.
