NWEA MAP test 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 a 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 ReadyScores by grade level, testing season, and subject. Understanding RIT scores, percentiles, and growth can help parents make better sense of their child’s results.



What Does an NWEA MAP Test 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.



Understanding MAP Math Test Scores



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 answers.



Parents can review a math RIT score alongside the appropriate grade-level national average and achievement percentile. Comparing math results from Fall, Winter, and Spring can also help show how a student’s performance changes over time.



There is no single math RIT score that is considered good for every grade. The student’s grade and testing season must be considered when interpreting the result.



Understanding MAP Reading Test Scores



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



Parents can compare a reading RIT score with current national reference data for the student’s grade and testing season. Reviewing previous results can also help families understand whether the student is making progress.



Reading and math performance may not be the same. A student can have different achievement levels and growth patterns across subjects, so each result should be interpreted separately.



What Is a MAP RIT Score?



The RIT score is the main numerical result reported by MAP Growth. Because it uses an equal-interval scale, changes in RIT scores can help show academic growth between testing periods.



A RIT score is not a percentage or a number of questions answered correctly. It represents a student’s measured achievement on the MAP Growth scale.



Parents should use the RIT score together with grade, subject, season, percentile, and previous results to understand what the score means.



What Is a MAP Achievement Percentile?



An achievement percentile shows a student’s relative performance compared with students in the same grade nationally.



For example, a percentile rank of 80 means the student performed as well as or better than approximately 80 percent of students in the comparison group.



A percentile is not the same as a percentage score. It does not mean the student answered 80 percent of the questions correctly.



Instead, it provides context about where the student’s performance falls within the national comparison group.



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.



For example, a student may have a lower achievement percentile but a strong growth percentile. This can indicate that the student has made substantial progress compared with students who started at a similar level.



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.



Why Grade Level and Testing Season Matter



MAP test scores should always be interpreted according to grade level and testing season.



MAP Growth assessments may be taken during Fall, Winter, or Spring. Each season has appropriate national comparison information.



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



How Parents Can Understand Progress



Parents can compare MAP test scores from different testing periods to understand academic progress.



A Fall score can provide a starting point for the school year. A Winter result can show progress during the year, while a Spring result can help families understand achievement later in the school year.



Looking at multiple results is generally more informative than focusing on one score.



Parents can also discuss results with teachers to understand which skills are developing well and where additional support may be useful.



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 families interpret MAP test results using the updated 2025 norms.



One MAP Test Score Does Not Tell the Full Story



Parents should remember that one MAP test score does not describe a child’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 useful information.



Looking at RIT scores, percentiles, growth, grade level, subject, and testing season together gives parents a more complete picture of student progress.
