If you've ever looked at your child's NWEA MAP Growth report and wondered whether their score is actually good for their grade, you're not alone. MAP scores are much easier to understand when you compare them with the average RIT score for the same grade, subject, and testing season. For the 2026–2027 school year, the latest 2025 MAP Growth norms provide updated national reference points that help parents and educators see where a student's achievement stands.
NWEA MAP Growth is a computer-adaptive assessment. Instead of giving every student exactly the same questions, the test adjusts the difficulty as the student answers. This allows MAP Growth to estimate a student's achievement on the RIT scale and measure progress over time.
Whether you're checking a Kindergarten reading score, a Grade 5 math score, or a high-school science result, knowing the typical RIT score for that grade gives you a much faster way to put the result into context.
What Is an Average NWEA MAP Score by Grade?
An average MAP score is the typical RIT score for students in a particular grade, subject, and testing season. Because students generally learn and develop throughout the school year, the average RIT score usually increases from Fall to Winter and again from Winter to Spring.
For example, a student's Fall RIT score should generally be compared with the Fall national average rather than a Spring average. Comparing different seasons can make a student's performance appear higher or lower than it really is.
When looking up an average MAP score, always consider:
Grade level
Subject
Testing season
Average national RIT score
Achievement percentile
Previous MAP score
Growth between testing periods
This makes grade-level MAP score charts much more useful than looking at a RIT number by itself.
Why Grade Level Matters When Reading MAP Scores
A RIT score has meaning only when you know what it is being compared against. A score that is typical for one grade may be considerably above or below average for another.
For instance, a RIT score in elementary school cannot simply be judged against a high-school RIT score without considering the grade and subject. The RIT scale is designed to measure achievement across a wide range, but interpretation still depends on the student's instructional level and testing context.
That's why a good MAP score chart should show the expected or average scores separately for each grade and testing season.
MAP RIT Scores and the 2026–2027 School Year
For 2026–2027, the important reference point is NWEA's 2025 MAP Growth norms. These updated norms are used to compare student performance with a nationally representative group of students.
The RIT scale itself has not been changed. Instead, the comparison data used to interpret scores has been updated. This matters because an identical RIT score can have a different percentile ranking under newer norms than it did under older norms.
If you're using an older MAP score chart from 2020 norms, the percentile or national comparison may not match what appears on a current MAP Growth report.
Average MAP scores by grade level What to Check
MAP Growth is available in multiple subjects, and average scores vary by subject. The most common areas families see include:
MAP Math Scores by Grade
Math MAP scores generally increase as students progress through school. A Grade 2 student's average RIT score is not expected to be the same as a Grade 6 student's average.
When evaluating a math score, compare the student's RIT with the national average for the same:
Grade
Testing season
Math assessment
Norm group
A score above the grade-level average generally indicates achievement above the national mean, while a score below the average indicates the student is performing below that particular comparison point.
MAP Reading Scores by Grade
Reading scores also change throughout the school year and across grade levels. A student's reading RIT should therefore be compared with the appropriate grade and season.
Reading MAP results can help show whether a student is performing around, above, or below the national achievement average and whether their performance is changing over time.
MAP Science Scores by Grade
MAP Growth Science is another assessment area where grade and season matter. Science testing availability can vary by grade and school, so families should use the appropriate science norms when interpreting a result.
Rather than asking whether a science RIT score is simply “good,” it is more useful to ask how it compares with the national average for that grade and testing season.
MAP Language Scores by Grade
Language Usage scores measure skills related to areas such as grammar, usage, mechanics, and written language conventions.
As with math and reading, the best comparison is the student's RIT score against the appropriate grade-level and seasonal reference point.
Fall, Winter, and Spring MAP Scores
One of the easiest mistakes to make is comparing a student's score with the wrong testing season.
MAP Growth is commonly administered during three periods:
Fall: Establishes a starting point for the academic year.
Winter: Shows progress partway through the school year.
Spring: Provides an end-of-year achievement and growth snapshot.
Because students are expected to gain knowledge throughout the year, average RIT scores typically rise from Fall to Winter and Spring.
For this reason, a student's Spring score should not automatically be compared with the Fall average. The most meaningful comparison is between the student's score and the average for the same grade, subject, and season.
RIT Score vs. Percentile: What's the Difference?
RIT and percentile answer two different questions.
The RIT score estimates a student's achievement on the MAP Growth scale. Because the RIT scale is an equal-interval scale, changes in RIT scores can be used to measure academic growth over time.
The percentile rank tells you how the student's achievement compares with students in the national comparison group.
For example, if a student has an achievement percentile of 75, that means the student's score is at or above the performance of approximately 75% of students in the relevant comparison group.
A percentile is therefore useful for understanding relative standing, while the RIT score is especially useful for tracking achievement and growth.
Is a MAP Score Above Average Good?
Generally, a RIT score above the national average for the same grade, subject, and season indicates achievement above the national average.
However, “good” should not be based on the average alone.
Parents should also look at:
The student's previous RIT score
RIT growth
Achievement percentile
Growth percentile
Instructional areas
School or district goals
Projected proficiency information
A student can have a score below the national average and still make excellent academic growth. Likewise, a student with a high RIT score may need additional challenges if their growth has slowed.
How to Find the Average MAP Score Quickly
If you want to interpret a MAP result quickly, use this simple process:
Step 1: Find the RIT score.
Look at the student's MAP Growth report and identify the RIT score.
Step 2: Identify the subject.
Determine whether the score is for math, reading, science, or language.
Step 3: Check the grade.
Use the student's actual grade level for the appropriate comparison.
Step 4: Check the season.
Determine whether the test was taken in Fall, Winter, or Spring.
Step 5: Compare with the current average.
Use the latest 2025 norms rather than relying on an outdated chart.
Step 6: Look beyond the average.
Check the achievement percentile and growth information to understand the result more completely.
This approach makes it much easier to answer the question, “Is my child's MAP score average for their grade?”
Quick-Lookup MAP Score Charts by Grade
For families who want to find an average RIT score without searching through complicated assessment tables, grade-level MAP score charts can make the process much faster.
Useful reference charts include:
NWEA MAP Math Scores by Grade — Fall, Winter, and Spring RIT comparisons across grade levels.
NWEA MAP Reading Scores by Grade — Grade-level reading averages and seasonal comparisons.
NWEA MAP Science Scores by Grade — Reference information for MAP Growth Science assessments.
NWEA MAP Language Scores by Grade — Grade-level comparisons for language achievement.
These charts are most useful when they are based on the current 2025 MAP Growth norms used for the 2026–2027 school year.
Don't Judge a MAP Score by One Number
A MAP RIT score is only one part of the assessment picture. Two students with the same RIT score can have different learning needs, strengths, and growth patterns.
For example, one student might have maintained a high score over several testing periods, while another might have made significant growth from a lower starting point. Looking only at the final RIT number would miss that difference.
This is why MAP Growth reports provide information about both achievement and growth.
The most useful question isn't simply:
“What is my child's MAP score?”
It is:
“How does my child's score compare with students in the same grade and season, and how much has my child grown?”
