NWEA MAP scores by grade 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.

What Are the New 2025 MAP Norms?

The 2025 MAP Growth norms provide updated national comparison information for interpreting student results. The RIT scale itself has not changed, but the national reference points used to interpret scores 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.

This is why parents should use current MAP score charts for the 2026–2027 school year rather than relying on older charts found online.

How Do MAP Scores Vary by Grade?

MAP results should always be interpreted according to the student’s grade level. A RIT score that is typical for one grade may have a different meaning for another grade.

Parents should also consider the subject and testing season. Fall, Winter, and Spring results have different national comparison points, so using the correct chart is important when reviewing a child’s performance.

Looking at grade-level results can help families understand whether a student’s score is near, above, or below the national reference point for the appropriate comparison group.

Understanding MAP Math Scores

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

Parents can compare a math RIT score with students in the same grade and testing season. Comparing results from Fall, Winter, and Spring can also help families see whether a student is making progress during the school year.

Understanding MAP Reading Scores

MAP reading scores provide information about a student’s 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 the appropriate grade-level and testing-season information. Looking at several testing periods can provide a better picture of reading progress than reviewing one score alone.

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 a national comparison of relative performance.

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 information. Achievement shows where a student currently performs compared with national peers, while growth shows how the student’s progress compares 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 consider both achievement and growth when reviewing MAP results.

Why Testing Season Matters

MAP Growth assessments are commonly administered during Fall, Winter, and Spring testing periods. Each season provides a different reference point for understanding student performance.

Fall scores generally represent performance near the beginning of the school year. Winter results provide information about progress during the year, while Spring results show performance later in the academic year.

Parents should use the chart that matches the student’s grade, subject, and testing season for a more meaningful comparison.

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

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 have an achievement percentile below the national average but demonstrate strong growth between Fall and Spring. Another student may have a high achievement percentile but show more moderate growth.

Looking at achievement and growth together provides a more complete picture of a student’s academic development.
