NWEA MAP scores help parents and teachers understand a student’s current achievement level and academic growth in subjects such as reading, mathematics, language usage, and science. 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 the student knows now and what they are ready to learn next.

For the 2026–2027 school year, schools are using the updated 2025 MAP Growth norms. These norms provide the national comparison data used to interpret MAP scores by grade level, testing season, and subject. The updated norms give families more current information when comparing student achievement and growth with national results.

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.

How to Compare MAP Math and Reading Scores

MAP math and reading scores both use the RIT scale, but parents should not assume that the same RIT score has exactly the same meaning across every subject.

The most useful comparison is within the appropriate subject, grade level, and testing season. Parents can review math and reading results separately and then consider the achievement percentile and growth information for each subject.

This can help families understand whether a student is performing similarly across subjects or showing different levels of achievement and growth.

Understanding MAP Math Performance

MAP math scores provide information about a student’s mathematics achievement and academic growth. Since MAP Growth is computer-adaptive, the difficulty of math questions changes according to the student’s answers.

Parents should compare a math RIT score with students in the same grade and testing season. Comparing Fall, Winter, and Spring results can also help families understand how a student’s math performance changes throughout the school year.

A single math score does not provide a complete picture of a student's mathematics ability.

Understanding MAP Reading Performance

MAP reading scores provide information about a student’s current reading achievement and growth. The results can help teachers identify areas where a student may need additional instruction 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 reading results over time can provide a better understanding of progress than focusing on one score.

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 information about the student’s relative performance compared with other students.

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 comparing academic performance.

Why Grade Level and Testing Season Matter

MAP results should always be interpreted according to the student’s grade, subject, and testing season.

Fall, Winter, and Spring results have different national comparison points. A score should therefore be compared with students who took the assessment in the same grade and testing period.

Using the correct comparison group makes it easier for parents to understand whether a result is near, above, or below the appropriate national reference point.

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.

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 NWEA MAP scores by grade level in math as published on www.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 make more accurate comparisons based on the updated 2025 norms.

One MAP 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 perform stronger in reading than math but show faster growth in mathematics. Looking at both achievement and growth can help parents understand these differences more clearly.

Parents can also discuss results with teachers to understand which skills are developing well and what the student may be ready to learn next.
