NWEA MAP scores help parents and teachers understand a student’s current achievement level and academic growth in subjects such as mathematics and reading. 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 the 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 national comparison data used to interpret MAP scores by grade level, testing season, and subject. Because MAP results depend on several factors, there is no single score that can be called «good» for every student.
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
These factors provide more useful context than looking at the RIT number alone.
Is There a Good NWEA MAP Score?
There is no universal «good» MAP score.
A score that is strong for one grade may be typical or low for another grade. The same principle applies to mathematics and reading because each subject has its own achievement scale and national comparison information.
Parents should use a current MAP score chart that matches the student’s grade, subject, and testing season.
A better question than «Is this a good score?» is:
How does my child’s score compare with the appropriate national reference group, and how much progress has my child made?
What Is a Good MAP Math Score?
A good MAP math score depends on the student’s grade and testing season.
MAP Growth mathematics results are reported using the RIT scale. Parents can compare a student's math RIT score with the appropriate national grade-level information and achievement percentile.
Math performance should also be reviewed across multiple testing periods. For example, comparing Fall and Spring results can help parents understand whether the student has made measurable progress during the school year.
A strong math result is not determined by one universal RIT number. Grade-level and seasonal context are essential.
What Is a Good MAP Reading Score?
A good MAP reading score also depends on grade level and testing season.
Parents can review the student's reading RIT score, achievement percentile, and previous MAP results to understand current performance and progress.
A student may have a different percentile in reading than in math, and that is completely normal. Students can have different strengths across academic subjects.
Reading results should therefore be interpreted separately using the appropriate grade-level and seasonal reference data.
How Do MAP Percentiles Work?
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 comparable students.
A percentile is not a percentage score. A student at the 72nd percentile did not necessarily answer 72 percent of the questions correctly.
Instead, the percentile describes the student’s relative position within the national comparison group.
What Is Considered a High MAP Percentile?
Higher percentiles indicate that a student's performance is higher than a larger portion of the comparison group.
For example, a student at the 85th percentile performed as well as or better than approximately 85 percent of comparable students.
However, percentile results should always be interpreted alongside the RIT score, grade, subject, and testing season.
A percentile alone does not explain everything about a student's academic skills or learning needs.
Why Grade Level Matters
MAP scores must be interpreted according to grade level.
National achievement patterns differ between grades, so a RIT score that is strong for one grade may have a different interpretation for another.
Parents looking for a «good» score should first identify:
The student's grade
The subject
The testing season
The RIT score
The achievement percentile
This provides a much more meaningful interpretation.
Why Fall, Winter, and Spring Scores Are Different
MAP Growth assessments may be administered during Fall, Winter, and Spring.
Fall results often provide a starting point for the school year. Winter results can show progress during the academic year, while Spring results can provide information about achievement later in the year.
Because students are expected to grow during the school year, seasonal MAP score ranges are different.
Parents should compare a student's result with the appropriate testing-season reference information rather than using one chart for every assessment.
Understanding MAP Growth
MAP Growth measures more than current achievement.
A student with a lower achievement percentile may still demonstrate strong growth. Similarly, a student with a high achievement percentile can continue to make progress.
This is why both achievement and growth are important when evaluating MAP results.
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.
An achievement percentile answers:
«How is my child performing compared with other students?»
A growth percentile answers:
«How does my child’s progress compare with students who started at a similar level?»
Both measures can help parents understand different aspects of a student's academic performance.
What Changed With the 2025 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 relying on older charts found online.
Should Parents Compare MAP Scores With Older Charts?
Parents should be cautious when using older MAP score charts.
A chart based on the 2020 norms may produce a different percentile from a chart based on the updated 2025 norms, even when the student's RIT score is identical.
The RIT scale has remained the same, but the national comparison data has been updated.
For 2026–2027 results, current charts based on the 2025 norms are the better reference for interpreting percentiles.
How Parents Can Tell if a MAP Score Is Strong
Parents can use several pieces of information instead of focusing on one number.
First, check the student's grade and subject. Next, identify the testing season and review the RIT score.
Then look at the achievement percentile and compare the current RIT score with previous MAP results.
Finally, review the growth information to understand how the student's progress compares with students who had similar starting scores.
This approach provides a more complete picture of performance.
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 parents understand whether a score is relatively high, typical, or lower compared with the appropriate national reference group.
One MAP Score Does Not Tell the Full Story
Parents should remember that one MAP score does not define a student's complete academic ability.
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.
The best way to understand a MAP result is to consider the RIT score, percentile, growth, grade, subject, and testing season together.
