NWEA MAP Score Ranges: Math and Reading Levels by Grade
NWEA MAP score ranges help parents and teachers understand a student’s current achievement level and academic growth in subjects such as reading and mathematics. 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 are ready to learn next.
MAP score ranges can vary by grade level, subject, and testing season. For this reason, parents should use the appropriate MAP score chart when reviewing a child’s results.
For the 2026–2027 school year, schools are using the updated 2025 MAP Growth norms. These norms provide national comparison data used to interpret MAP scores by grade level, testing season, and subject.
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 MAP Score Ranges?
MAP score ranges provide a way to organize RIT scores and compare them with national reference information. A score range should always be considered in relation to grade level, subject, and testing season.
There is no single score range that applies equally to every student. A RIT score can have a different interpretation depending on the student's grade and whether the assessment was taken in Fall, Winter, or Spring.
Parents should therefore use current charts rather than relying on general score ranges without context.
Understanding MAP Math Score Ranges
MAP math scores provide information about a student’s mathematics achievement and growth. Because MAP Growth is computer-adaptive, the difficulty of math questions changes according to the student’s answers.
Parents can use grade-level math score charts to compare a child’s RIT score with national results for the appropriate testing season.
Comparing math scores from Fall, Winter, and Spring can also help families understand whether a student is making progress during the school year.
Understanding MAP Reading Score Ranges
MAP reading scores provide information about a student’s current reading achievement and academic growth. The results can help teachers identify areas where a student may need additional support or where the student may be ready for more advanced learning.
Parents should compare reading results with students in the same grade and testing season. Looking at multiple testing periods can provide a clearer picture of reading growth over time.
Why Grade Level Matters
Grade level is an important part of interpreting MAP score ranges. Students are expected to develop academically as they move through different grades, so national reference points change accordingly.
A RIT score that is typical for one grade may have a different meaning for another grade. Parents should always select the chart that matches the child’s current grade and subject.
This helps prevent incorrect comparisons and gives families a more useful understanding of the student's performance.
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.
What Is an Achievement Percentile?
An achievement percentile shows how a student performed compared with students in the same grade nationally.
For example, a percentile rank of 72 means the student performed as well as or better than approximately 72 percent of students in the comparison group.
A percentile is not a percentage score. A student at the 72nd percentile did not necessarily answer 72 percent of questions correctly.
Instead, the percentile provides a national comparison of relative performance.
What Is a Growth Percentile?
A growth percentile measures how a student’s progress compares with students who had similar starting scores.
Achievement and growth provide different types of information. Achievement shows where a student currently performs, while growth shows how the student’s progress compares with similar students.
A student can have a lower achievement percentile while demonstrating strong growth. Another student may have a high achievement percentile but show more moderate growth.
Parents should consider both measurements when reviewing MAP results.
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 for the 2026–2027 school year because the updated 2025 norms may produce different percentile comparisons than older charts.
One 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.
For example, a student may have an achievement score below the national average but demonstrate strong growth between Fall and Spring. Another student may have a high achievement score but show more moderate growth.
Looking at achievement and growth together provides a more complete picture of academic development.
