NWEA MAP scores by grade level help parents and teachers understand a student’s current achievement and academic growth in mathematics and reading. MAP Growth is a computer-adaptive assessment, which means the difficulty of questions changes based on a student’s answers. This allows the assessment to measure what a student knows and what they may be ready to learn next.



For the 2026–2027 school year, families should use the updated 2025 MAP Growth norms when interpreting results. These norms provide national comparison data for MAP scores by grade level, subject, and testing season. Understanding the grade, subject, RIT score, percentile, and testing period can make MAP results much easier to understand.



What Are NWEA MAP Scores?



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 represents a student’s measured achievement on the MAP Growth scale. However, the score should not be interpreted by itself.



Parents should consider:



The student’s grade level

The subject tested

The Fall, Winter, or Spring testing season

The national grade-level mean

The achievement percentile

Previous MAP results

Growth between testing periods



Together, these factors provide a clearer picture of academic performance.



Why Grade Level Matters



MAP scores are interpreted according to the student’s grade level because national comparison data varies by grade.



A RIT score that is typical for one grade may have a different interpretation for another grade. Parents should therefore use a score chart that matches the student’s grade, subject, and testing season.



Grade-level comparisons are particularly useful when reviewing national averages and percentile ranges.



NWEA MAP Math Scores by Grade



MAP math scores provide information about a student’s mathematics achievement and growth.



Because MAP Growth is computer-adaptive, the assessment adjusts the difficulty of math questions based on the student’s responses. This helps provide an estimate of the student’s current mathematical achievement.



Parents can review math RIT scores across Fall, Winter, and Spring to see how performance changes during the school year.



A math score should be compared with the appropriate grade-level reference information rather than with a general score range.



NWEA MAP Reading Scores by Grade



MAP reading scores provide information about a student’s reading achievement and growth.



Parents can use reading RIT scores and percentile information to understand how a student’s performance compares with students in the same grade nationally.



Comparing results from multiple testing periods can also help show whether a student is making progress over time.



Reading results should be considered alongside classroom performance, teacher feedback, and other academic information.



Understanding the MAP RIT Scale



The RIT scale is designed to measure achievement and growth consistently over time.



For example, if a student's RIT score increases between Fall and Spring, the change can provide information about academic growth.



However, parents should not assume that every increase has the same educational meaning. Growth should be interpreted according to the subject, grade, testing season, and appropriate norms.



What Is a MAP 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 comparable students.



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 within the national comparison group.



Understanding Math Percentiles



Math percentiles help parents understand how a student’s mathematics achievement compares with other students in the same grade.



A high percentile indicates that the student performed higher than a large portion of the comparison group, while a lower percentile indicates that the student performed below a larger portion of the group.



Parents should also review the RIT score and growth information instead of focusing only on the percentile.



Understanding Reading Percentiles



Reading percentiles provide similar national comparison information for reading achievement.



For example, a student's reading percentile can help parents understand whether current performance is near the middle, above the middle, or below the middle of the national comparison group.



The percentile should always be interpreted according to the student's grade and testing season.



Fall, Winter, and Spring MAP Scores



MAP Growth assessments may be taken during Fall, Winter, and Spring.



Fall results can provide a starting point for the academic year.



Winter results can show progress during the school year.



Spring results can provide information about achievement later in the academic year.



Comparing results across these testing periods can help parents and teachers understand changes in a student's achievement and growth.



What Are MAP Growth Scores?



MAP Growth scores help show how a student's achievement changes between testing periods.



Growth is different from achievement. Achievement describes a student's current performance, while growth describes progress over time.



A student may have a lower achievement percentile but demonstrate strong growth. Another student may have a high achievement percentile but show more moderate growth.



This is why parents should consider both achievement and growth when reviewing MAP results.



What Is a Growth Percentile?



A growth percentile measures how a student's progress compares with students who had similar starting scores.



For example, a student with a strong growth percentile has made more progress than many students with similar starting achievement.



Growth percentiles can be particularly helpful when parents want to understand progress rather than only current 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 correspond to a somewhat different percentile than it did under the older norms.



Families reviewing MAP scores in 2026 and 2027 should therefore use current charts based on the 2025 norms instead of relying on older charts found online.



How Parents Can Read a MAP Score Chart



Parents can follow a few simple steps when reviewing a MAP score chart.



First, identify the student's grade and subject. Next, determine whether the assessment was taken during Fall, Winter, or Spring.



Then locate the student's RIT score and compare it with the appropriate national reference information.



Finally, review the achievement percentile and previous results to understand both current performance and progress.



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 see the updated NWEA MAP score charts for 2026 and 2027 as published on 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.



Current charts are especially useful for the 2026–2027 school year because the updated 2025 norms may produce different percentile comparisons than older reference charts.



Should Parents Focus on One Score?



Parents should not judge a student's academic performance using only one MAP score.



A single result does not show the full story. Looking at achievement, growth, percentile, previous scores, and classroom performance provides a more complete picture.



The MAP Growth Family Report combines achievement, growth, and projected proficiency so families can see both current performance and progress over time.



Math and Reading Results Together



Reviewing math and reading results together can help parents understand whether a student's strengths and areas for development differ between subjects.



For example, a student may perform above the national comparison point in reading while showing different results in mathematics.



This does not necessarily indicate a problem. Students can develop skills at different rates across academic subjects.



The most useful approach is to examine each subject using its appropriate grade-level and seasonal reference information.
