NWEA MAP scores help parents and teachers understand a student’s current achievement level and academic growth in subjects such as reading, mathematics, language usage, and science. MAP Growth is a computer-adaptive assessment, which means the difficulty of the questions changes according to the student’s answers. The goal is to measure what a student knows now and what they may be ready to learn next.
For the 2026–2027 school year, schools are using the updated 2025 MAP Growth norms. These norms provide the national comparison data used to interpret MAP scores by grade level, testing season, and subject. Understanding math, reading, RIT scores, percentiles, and growth can help parents make better sense of their child’s results.
What Does an NWEA MAP Score Mean?
MAP Growth results are reported using the RIT scale. RIT stands for Rasch Unit. It is an equal-interval scale, similar to the marks on a ruler, so a ten-point increase represents the same amount of measured growth at different points on the scale.
A RIT score should not be interpreted by itself. Parents should compare it with:
- The student’s grade
- The subject tested
- The Fall, Winter, or Spring testing season
- The national grade-level mean
- The student’s achievement percentile
- Growth between testing periods
An achievement percentile shows how a student performed compared with same-grade students nationally. For example, a percentile rank of 72 means the student scored as well as or better than approximately 72 percent of comparable students.
Understanding MAP Math Scores
MAP math scores provide information about a student’s mathematics achievement and growth.
Because MAP Growth is computer-adaptive, the difficulty of mathematics questions changes according to the student’s answers. This helps measure the student’s performance across a range of mathematical skills.
Parents should review the math RIT score alongside the appropriate grade-level national average and achievement percentile.
Comparing math results from Fall, Winter, and Spring can also help show how a student’s measured achievement changes throughout the school year.
Understanding MAP Reading Scores
MAP reading scores provide information about reading achievement and academic growth.
Parents can compare a student’s reading RIT score with current national reference data for the appropriate grade and testing season.
Reading performance can develop differently from mathematics performance. A student may have different achievement levels or growth patterns in each subject, so math and reading results should be interpreted separately.
What Is a MAP RIT Score?
The RIT score is the main numerical result reported by MAP Growth.
RIT scores use an equal-interval scale, which makes them useful for tracking changes between testing periods. For example, parents can compare a student's Fall and Spring RIT scores to understand how the measured achievement changed during the year.
A RIT score is not a percentage or the number of questions answered correctly. It should be interpreted using the student’s grade, subject, testing season, and current MAP norms.
What Does an Achievement Percentile Mean?
An achievement percentile shows how a student performed compared with students in the same grade nationally.
For example, a percentile rank of 80 means the student performed as well as or better than approximately 80 percent of comparable students.
A percentile is not the same as a percentage score. A student at the 80th percentile did not necessarily answer 80 percent of the questions correctly.
Instead, the percentile provides context about the student's relative position within the national comparison group.
What Is a MAP Growth Percentile?
A growth percentile measures how a student’s progress compares with students who had similar starting scores.
This is different from an achievement percentile. Achievement describes current performance, while growth describes progress between testing periods.
A student may have a lower achievement percentile but demonstrate strong growth. Similarly, a student with a high achievement percentile can continue to make meaningful progress.
Parents should consider both measures when reviewing MAP results.
How Parents Can Understand Student Growth
Parents can compare MAP results from different testing periods to understand academic progress.
A Fall assessment can provide a starting point for the school year. A Winter assessment can show progress during the year, while a Spring assessment can help families understand achievement later in the school year.
Looking at several testing periods is generally more useful than focusing on one score.
Parents can also discuss MAP results with teachers to understand which skills are developing well and where additional support may be helpful.
What Changed in the New MAP Norms?
The RIT scale itself has not changed, but the national reference points have. NWEA reports that the 2025 norms generally reflect lower national achievement than the previous 2020 norms, with larger differences among lower-performing students.
As a result, the same RIT score may now correspond to a somewhat different percentile than it did under the older norms.
This is why families should use current NWEA MAP score charts for 2026 and 2027 rather than older charts found online check out the NWEA MAP scores by grade level in reading for 2026 and 2027 according to ReadyScores.com.
Why Grade and Testing Season Matter
MAP scores should always be interpreted according to the student’s grade and testing season.
MAP Growth assessments may be taken during Fall, Winter, or Spring. Each season provides appropriate national comparison information.
A RIT score that is typical for one grade or season may have a different interpretation for another. Parents should therefore use a chart that matches the student's grade, subject, and testing period.
Find MAP Scores by Grade Level
You can view updated NWEA MAP scores by grade level, MAP score charts, national averages, percentile ranges, and typical Fall, Winter, and Spring scores at ReadyScores.com.
The charts make it easier to compare a child’s score with students in the same grade and testing season. Separate information is available for MAP reading scores, MAP math scores, language usage, and science.
Using current charts can help families interpret RIT scores, national averages, percentiles, and growth using the updated 2025 norms.
One MAP Score Does Not Tell the Full Story
Parents should remember that one MAP score does not tell the full story. The MAP Growth Family Report combines achievement, growth, and projected proficiency so families can see both current performance and progress over time.
Classroom performance, teacher feedback, assignments, and other assessments can also provide valuable information about a student’s learning.
Looking at RIT scores, percentiles, growth, grade level, subject, and testing season together provides a more complete picture of academic progress.
