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 questions changes according to the student’s answers. The goal is to measure what a student knows now and what they are ready to learn next.
For 2026, 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. NWEA updated the norms to provide more current information about student achievement and growth.
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. A growth percentile measures how the student’s progress compares with students who had similar starting scores.
What Are the New MAP Norms?
The 2025 MAP Growth norms provide updated national reference information for interpreting student results in 2026 and beyond.
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 rather than older charts based on the 2020 norms.
Understanding MAP Math Scores
MAP math scores provide information about a student's mathematics achievement and academic growth. Since MAP Growth is computer-adaptive, the difficulty of math questions changes based on the student's answers.
Parents should compare a math RIT score with students in the same grade and testing season. A score that may be typical for one grade can have a different meaning for another grade.
Comparing Fall, Winter, and Spring math scores can also help families understand how much progress a student has made during the school year.
Understanding MAP Reading Scores
MAP reading scores provide information about a student's reading achievement and growth. The assessment can help teachers understand a student's current learning level and identify areas where additional instruction may be useful.
Parents should consider grade level and testing season when reviewing reading results.
Comparing reading scores from multiple testing periods can provide a clearer picture of academic progress than looking at one score alone.
Why Testing Season Matters
MAP Growth results are commonly collected during Fall, Winter, and Spring testing periods. Each season provides a different point of comparison because students are expected to make academic progress throughout the school year.
A Fall result should be compared with appropriate Fall information. Similarly, Winter and Spring results should be compared with the corresponding testing-season data.
Using the correct testing season helps parents make a more meaningful comparison.
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 is especially important in 2026 because the updated norms may produce different percentile comparisons than older charts.
One MAP Score Does Not Tell the Full Story
Parents should remember that one 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.
For example, a student may have an achievement percentile below the national average but demonstrate strong growth. Another student may have a high achievement percentile but show more moderate growth.
