NWEA MAP 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 the questions changes based on how a student answers. The purpose is to measure what a student knows today and identify areas where the student may be ready to learn more.

MAP Growth results can be useful for understanding both achievement and progress. Instead of looking only at whether a student answered a certain number of questions correctly, the assessment uses the RIT scale to provide a score that can be compared across testing periods.

For the 2026–2027 school year, families should use the updated 2025 MAP Growth norms when interpreting results. These norms provide current national comparison information for different grades, subjects, and testing seasons.

What Is an NWEA MAP Score?

NWEA MAP scores are reported using the RIT scale. RIT stands for Rasch Unit. The scale is designed as an equal-interval scale, which means that changes in score can be compared across different points on the scale.

For example, a student who increases from a RIT score of 190 to 200 has gained 10 RIT points. A later increase from 210 to 220 also represents 10 points of measured growth.

However, a RIT score should not be considered a complete measure of academic performance. Parents should look at the score together with other information, including:

• The student’s grade level
• The subject being tested
• The Fall, Winter, or Spring testing season
• The national grade-level average
• The achievement percentile
• Growth between testing periods
• Projected academic outcomes

Looking at these factors together gives families a better understanding of a student’s performance.

Understanding MAP Math Scores

MAP math scores provide information about a student’s achievement and growth in mathematics. Because MAP Growth is computer-adaptive, students receive questions that adjust according to their responses.

A student who answers questions correctly may receive more challenging questions, while a student who needs additional support may receive questions at an appropriate level. This allows the assessment to estimate a student’s instructional level more precisely.

Parents should avoid deciding whether a math score is “good” or “bad” based only on the RIT number. A score that is typical for one grade may be below or above average for another grade.

The testing season also matters. Fall, Winter, and Spring scores are compared with different national reference points because students are expected to develop academically throughout the school year.

Understanding MAP Reading Scores

MAP reading scores help show a student’s current reading achievement and academic growth. The assessment can provide information that helps teachers identify areas where students may need additional instruction or opportunities for more advanced learning.

As with mathematics, reading scores should be considered in relation to grade level and testing season. A student’s Spring score may naturally be higher than the same student’s Fall score because the student has had additional time to learn and practice.

Parents can also compare reading results across testing periods to see whether the student is making progress.

What Is a MAP RIT Score?

The RIT score is one of the most important parts of a MAP Growth report. It provides a numerical measurement of achievement on the MAP Growth scale.

Because the RIT scale is designed as an equal-interval scale, it can be used to monitor changes in performance over time. This makes it useful for tracking academic growth from Fall to Winter and from Winter to Spring.

For example, if a student receives a math RIT score in the Fall and a higher score in the Spring, the difference between the two scores provides information about the student’s measured growth.

The RIT score does not represent a percentage or the number of questions answered correctly. It should be interpreted using the appropriate grade, subject, and testing season.

What Is an Achievement Percentile?

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

For example, an achievement percentile of 72 means the student performed as well as or better than approximately 72 percent of comparable students in the national comparison group.

A percentile is different from a RIT score. The RIT score represents a student’s position on the MAP Growth scale, while the percentile provides a comparison with other students.

This distinction is important because percentile rankings can change when national norms are updated, even when the underlying RIT score remains the same.

What Is a Growth Percentile?

A growth percentile measures how much a student has progressed compared with other students who had similar starting scores.

This is different from an achievement percentile.

A student could have an achievement percentile that is below the national average but still demonstrate strong academic growth. Likewise, a student with a high achievement percentile may not necessarily have experienced unusually high growth.

For this reason, parents should consider both achievement and growth when reviewing MAP results.

What Changed With the 2025 MAP Norms?

NWEA introduced updated MAP Growth norms based on more recent student performance data. These norms are important for interpreting MAP results during the 2026–2027 school year.

The RIT scale itself has not been replaced. Instead, the national comparison points used to interpret scores have been updated.

The 2025 norms generally show lower national achievement compared with the previous 2020 norms, with some of the larger differences appearing among lower-performing students.

Because the national reference data changed, the same RIT score may correspond to a different percentile under the newer norms.

This is one reason parents should be careful when using MAP score charts found on older websites. A chart based on the 2020 norms may not give the same percentile information as a chart based on the current 2025 norms.

Why Testing Season Matters

MAP Growth is commonly administered during Fall, Winter, and Spring testing periods. Each testing season provides a different point of comparison.

A Fall score shows where a student begins the school year. A Winter score can help show progress during the year, while a Spring score provides information about achievement near the end of the school year.

Parents should therefore avoid comparing a child's score with a national average without checking the testing season.

For example, a Fall math score should generally be compared with the appropriate Fall reference data rather than a Spring average.

How to Find MAP Scores by Grade Level

Parents looking for MAP scores by grade level can use current MAP score charts that organize results according to grade, subject, and testing season.

ReadyScores.com provides information about NWEA MAP scores, including grade-level score information, national averages, percentile ranges, and typical Fall, Winter, and Spring results.

Separate resources can help families review MAP reading scores, MAP math scores, language usage results, and science results.

Using a grade-specific chart makes it easier to understand where a student’s score falls compared with students in the same grade.

Should Parents Focus on One MAP Score?

No. One MAP score does not provide a complete picture of a student’s academic development.

MAP Growth is designed to provide information about both achievement and growth. Looking at several testing periods can help parents understand whether a student is making progress over time.

For example, a student may have a lower-than-average achievement score but show significant growth between Fall and Spring. That progress is important and should not be overlooked.

Similarly, a student with a high achievement score should continue to be monitored for appropriate academic growth.

The MAP Growth Family Report can help families review achievement, growth, and projected proficiency together.

How Parents Can Use MAP Results

Parents can use MAP results as one source of information when talking with teachers about their child’s education.

Useful questions may include:

• What does my child’s RIT score mean for this grade?
• How does the score compare with the national average?
• What is the student’s achievement percentile?
• How much growth occurred since the previous test?
• Which academic areas need additional practice?
• What skills is my child ready to learn next?
• How does the current result compare with previous MAP tests?

These questions can help parents move beyond simply asking whether a score is good or bad.

MAP Scores Are Only One Part of Student Progress

MAP Growth results can provide valuable information, but they should not be used as the only measure of a student’s academic ability.

Classroom performance, teacher observations, assignments, projects, attendance, participation, and other assessments can also provide important information.

A MAP score is most useful when it is viewed as part of a larger picture of learning.

Parents should also remember that academic growth can vary from student to student. Students may progress at different rates depending on their learning needs, previous achievement, instruction, and other factors.
