NWEA MAP score charts help parents and teachers understand student achievement and academic growth in mathematics and reading. MAP Growth is a computer-adaptive assessment, meaning the difficulty of questions changes based on how a student answers. This approach helps measure what a student knows and what they may be ready to learn next.
For the 2026–2027 school year, families should use current MAP Growth reference information based on the updated 2025 norms. These norms provide national comparison data for understanding MAP results by grade level, subject, and testing season.
What Is an NWEA MAP Score?
MAP Growth results are reported using the RIT scale. RIT stands for Rasch Unit. The RIT scale is an equal-interval scale, meaning that the difference between scores can be interpreted consistently across the scale.
For example, a 10-point increase represents the same amount of measured growth regardless of where the student starts on the RIT scale.
However, a RIT score should not be viewed by itself. Parents should consider the student’s:
Grade level
Subject
Fall, Winter, or Spring testing season
National grade-level average
Achievement percentile
Growth between testing periods
These factors provide a clearer picture of academic performance.
How to Use a MAP Score Chart in 2026
When reviewing a MAP score chart, parents should first identify the student’s grade and subject. Next, they should select the appropriate testing season.
Fall, Winter, and Spring results have different national comparison points. Therefore, comparing a student’s Fall score with a Spring reference point may lead to an inaccurate interpretation.
The best approach is to compare the student’s score with students in the same grade, subject, and testing season.
NWEA MAP Math Scores by Grade
MAP math scores provide information about a student’s mathematics achievement and growth. Because the assessment is computer-adaptive, the difficulty of math questions changes according to the student’s responses.
Parents can use grade-level math charts to understand how a student’s RIT score compares with national reference information.
It is also helpful to compare math scores from multiple testing periods. A student’s Fall, Winter, and Spring results can show how performance changes throughout the school year.
NWEA MAP Reading Scores by Grade
MAP reading scores provide information about a student’s current reading achievement and academic growth.
Reading results can help teachers identify areas where a student may need additional instruction and areas where the student may be ready for more advanced learning.
Parents should review reading scores according to grade level and testing season. Looking at multiple results over time can provide a more complete picture of reading development than focusing on one score.
What Is the MAP National Average?
The national average is a reference point that allows parents to compare a student’s performance with students in the same grade and testing season.
It should not be considered a required score or a fixed definition of success. Students have different learning experiences, educational needs, and rates of growth.
Instead, the national average provides context for understanding where a student's result falls compared with the broader national group.
Understanding MAP Percentiles
An achievement percentile shows how a student performed compared with students in the same grade nationally.
For example, a percentile rank of 72 means a 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 describes the student’s relative position compared with other students.
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 over time compared with similar students.
A student can have a lower achievement percentile and still demonstrate strong growth. Another student may have a high achievement percentile but show more moderate growth.
Parents should therefore review both achievement and growth when interpreting MAP results.
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 correspond to a somewhat different percentile under the updated norms.
This makes it important for families to use current MAP score charts for 2026 and 2027 rather than relying on older charts published online.
Comparing Fall, Winter, and Spring Scores
MAP Growth assessments may be administered during Fall, Winter, and Spring.
Fall results can establish a starting point for the academic year.
Winter results can show how a student’s performance has changed since the beginning of the year.
Spring results provide information later in the academic year and can be compared with earlier results to evaluate growth.
Reviewing all available testing periods can help parents see patterns that may not be obvious from a single score.
How Parents Can Read MAP Results
Parents do not need to be experts in assessment data to understand MAP results. Start by identifying the student's grade, subject, and testing season.
Then review the RIT score alongside the national average and achievement percentile. If previous results are available, compare them to see how the student’s score has changed.
Finally, consider the growth percentile and discuss the results with the student’s teacher when additional context is needed.

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 results according to the updated 2025 norms.
One MAP Score Does Not Tell the Whole Story
Parents should remember that one MAP score does not describe 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.
For example, a student may have a lower achievement percentile but demonstrate strong growth during the school year. Another student may have a high achievement percentile but show slower growth.
Looking at multiple measures provides a more balanced understanding of academic development.
