If you've ever opened your child's MAP Growth report and wondered whether the score is actually good, you're not alone. NWEA MAP scores can provide a detailed picture of a student's current achievement and academic growth in math, reading, language usage, and science, but the number only becomes meaningful when you know how to compare it.
For the 2026–2027 school year, families should pay particular attention to the updated 2025 MAP Growth norms. These norms provide the national comparison points used to understand how a student's RIT score compares with other students in the same grade, subject, and testing season.
So, what is considered a good MAP score? The short answer is: there isn't one single MAP score that is good for every student. A score should be interpreted based on grade level, subject, testing season, percentile rank, and individual growth.
What Is a Good NWEA MAP Score?
A good MAP score is generally one that places a student at or above the national average for their grade, subject, and testing season. However, being below the national average does not automatically mean a student is struggling, just as being above average does not tell the entire story.
For example, a student might have a RIT score below the national average but make significantly higher-than-expected growth between Fall and Spring. That growth can be an important indicator of academic progress.
When evaluating a MAP score, look at:
RIT score
Grade level
Subject
Fall, Winter, or Spring testing season
National percentile rank
Growth percentile
Previous MAP scores
Projected academic growth or proficiency
The combination of these numbers gives parents a much better understanding than the RIT score alone.
Understanding the MAP RIT Score
NWEA MAP Growth assessments use the RIT scale, which is an equal-interval scale designed to measure academic achievement and growth.
This means a student's RIT score can be compared across testing periods. If a student moves from a RIT score of 190 to 200, that 10-point increase represents the same amount of RIT-scale growth as a move from 210 to 220.
However, RIT scores should not be treated like traditional percentage grades. A score of 220 does not mean that a student answered 220 questions correctly or earned 220 out of 250 points.
The meaning of a RIT score depends heavily on the student's grade, subject, and testing season.
MAP Percentile: One of the Best Ways to Judge a Score
The percentile rank is often the easiest way for parents to understand how a student's achievement compares with other students nationally.
For example:
50th percentile: Around the national middle
60th percentile: Above approximately 60% of same-grade peers
75th percentile: Above approximately 75% of same-grade peers
90th percentile: Above approximately 90% of same-grade peers
95th percentile: Above approximately 95% of same-grade peers
A student at the 75th percentile is performing at or above the achievement level of roughly 75 percent of comparable students nationally.
But percentile rank should not be confused with growth percentile. Achievement percentile describes where the student's current performance stands compared with peers. Growth percentile describes how much the student progressed compared with students who had similar starting scores.
Is the 50th Percentile a Good MAP Score?
Yes. A score around the 50th percentile is generally considered to be around the national average for the student's grade and testing season.
Being at the 50th percentile does not mean a student is failing or behind. It means the student's achievement is approximately in the middle of the national comparison group.
Likewise, a student scoring at the 40th percentile can still demonstrate strong academic growth, while a student at the 90th percentile may need to continue making progress to remain on track.
The goal should not always be to reach the highest possible percentile. Instead, parents and teachers should consider whether the student is making appropriate progress from one testing period to the next.
Is a 200 MAP Score Good?
There is no universal answer to whether a 200 MAP score is good.
A RIT score of 200 can represent different achievement levels depending on the student's:
Grade
Subject
Testing season
National percentile
Previous MAP score
For a younger student, a 200 RIT score may be relatively strong in a particular subject, while the same score could be below the typical range for an older student.
This is why searching for a single "good MAP score" without including the grade and subject can produce misleading results.
Is a 220 MAP Score Good?
A 220 MAP score may be a strong result in one grade and subject but closer to average in another. The same principle applies to 210, 230, 240, or any other RIT score.
Instead of asking only, "Is 220 a good MAP score?" ask:
"Where does a 220 RIT score fall for this student's grade, subject, and testing season?"
Then compare it with the national percentile and the student's previous results.
That approach provides much more useful information about academic performance.
Why Testing Season Matters
MAP Growth scores naturally vary throughout the school year. Students may take MAP Growth assessments in Fall, Winter, and Spring, and the national comparison averages differ by testing season.
A Fall score should therefore not be judged against a Spring average.
For example, a score that looks strong compared with a Fall norm may not have the same percentile when compared with a Spring norm. This is one reason current MAP score charts should always identify the testing season.
What the 2025 MAP Growth Norms Mean for 2026–2027
For the 2026–2027 school year, the 2025 MAP Growth norms are an important reference point for interpreting student performance.
The RIT scale itself has not been replaced. Instead, the national comparison data used to interpret scores have been updated. The newer norms are designed to reflect more recent student performance and demographic patterns.
As a result, the percentile associated with a particular RIT score may differ from what parents see in older MAP charts based on the 2020 norms.
This is especially important when comparing information found online. A chart based on older norms may give a different impression of whether a score is average, above average, or below average.
Good MAP Scores by Subject
A good MAP score should also be evaluated separately for each subject.
Math
MAP Growth Math measures mathematical achievement across areas such as number sense, operations, algebraic thinking, geometry, and data.
A student's math RIT score should be compared with the appropriate grade-level and seasonal math norms.
Reading
MAP Growth Reading measures reading-related skills and comprehension. Reading scores can be interpreted using the student's grade, testing season, RIT score, and percentile rank.
Language
Language usage results can provide information about skills involving grammar, conventions, punctuation, and written language.
Science
MAP Growth Science scores should also be compared with the appropriate grade-level norms and testing season. Science testing availability and grade coverage can differ from other MAP Growth subjects.
Don't Ignore Growth
One of the biggest mistakes parents make is focusing entirely on achievement percentile.
MAP Growth is designed to measure growth as well as achievement. A student who starts below the national average but makes substantial progress may be demonstrating excellent academic development.
For example, consider two students:
Student A
Fall: 35th percentile
Spring: 45th percentile
Strong academic growth
Student B
Fall: 90th percentile
Spring: 88th percentile
Relatively limited growth
Student A may have made more meaningful progress even though Student B's achievement percentile remains much higher.
This is why MAP reports should be viewed as a combination of where a student is now and how far the student has progressed.
How to Tell If Your Child's MAP Score Is Good
A simple five-step approach can make a MAP report much easier to understand:
1. Find the RIT score.
This is the student's achievement score on the MAP Growth scale.
2. Identify the subject.
Math, Reading, Language, and Science have different score distributions.
3. Check the testing season.
Determine whether the test was taken in Fall, Winter, or Spring.
4. Look at the percentile.
This shows how the student's achievement compares with the national reference group.
5. Compare growth over time.
Look at previous MAP scores and the student's growth percentile rather than judging the latest score in isolation.
This gives parents a much more complete picture of performance.
MAP Scores Are Not School Grades
It is also important to remember that MAP Growth is not the same thing as a classroom report-card grade.
A report-card grade may reflect homework, projects, participation, classroom assessments, attendance, and other factors. MAP Growth is a standardized, computer-adaptive assessment designed to measure achievement and growth.
Therefore, a student receiving an A in math could have a MAP score around the national average, while another student with a lower classroom grade could have a high MAP percentile.
The two measures answer different questions.

These resources can help parents move beyond the question "Is this score good?" and understand what the score means for the student's particular grade, subject, and testing season.
Final Thoughts: What Counts as a Good MAP Score?
There is no single RIT number that qualifies as a "good" MAP score for every student. A good score is best understood relative to the student's grade, subject, testing season, percentile, and academic growth.
For 2026–2027, using the updated 2025 MAP Growth norms is particularly important because older score charts may use outdated national comparison data.
Most importantly, don't judge your child's progress from one number alone. A MAP report becomes much more useful when you look at the complete picture: current RIT achievement, national percentile, previous scores, growth percentile, and expected progress.
