MAP Test Scores: RIT, Percentiles, Growth, and Reports
A MAP Growth score report is designed to show current achievement and change over time. The main score is the RIT score, but a report may also include achievement percentiles, growth percentiles, projections, goal areas, and score ranges.
Each measure answers a different question.
For parents:
A MAP result is not a classroom grade, a percentage correct, or a pass-or-fail result. It is most useful when reviewed with previous MAP scores, classroom work, teacher observations, and the school’s instructional plan.
Optional TestPrep-Online preparation:
When your school permits practice, families can review TestPrep-Online MAP practice, MAP Shop and TestPrep-Online Family Membership. Confirm the assessment, grade or level, current pack contents, access terms, and school policy before purchasing.
What Is a MAP RIT Score?
RIT stands for Rasch Unit.
A RIT score places a student’s achievement on the MAP Growth measurement scale. The scale is designed to remain stable across grades so that schools can monitor change over time.
A RIT score is not:
- the percentage of questions answered correctly;
- a letter grade;
- a grade-equivalent score;
- an IQ score;
- a percentile;
- a universal pass mark.
The same RIT score can have a different interpretation depending on subject, grade, testing season, and applicable norms.
Why Can Students in Different Grades Have the Same RIT Score?
The RIT scale is grade-independent.
Two students in different grades can receive the same RIT score because the score describes a position on the achievement scale rather than a school-grade label.
Their percentiles may still differ because each student is compared with the appropriate grade and testing-season norm group.
What Is an Achievement Percentile?
An achievement percentile compares a student’s current result with students in the applicable norm group.
For example, a percentile of 70 generally means that the student scored as well as or better than approximately 70% of comparable students in the reference group.
It does not mean that the student answered 70% of the questions correctly.
Percentile interpretation depends on:
- subject;
- grade;
- testing season;
- weeks of instruction;
- the norm study used by the report.
What Changed With the 2025 MAP Growth Norms?
NWEA introduced updated MAP Growth achievement and growth norms in 2025.
The RIT scale itself remained stable. What changed was the reference used to translate scores into percentiles and growth expectations.
This means:
- the same RIT score may correspond to a different percentile under the 2025 norms;
- typical growth expectations may differ from those based on older norms;
- historical reports should not be compared without checking the norm version;
- local programme thresholds may need review when districts adopt new norms.
Check the norm year:
Do not assume that a percentile from a recent report is directly comparable with a percentile from an older report. Ask the school which MAP Growth norms were used.
What Is a Growth Percentile?
A growth percentile compares a student’s observed growth with the growth of academic peers who had a similar starting achievement level.
It does not show current achievement.
A student can have:
- high achievement and high growth;
- high achievement and lower growth;
- lower achievement and high growth;
- lower achievement and lower growth.
Growth and achievement should be discussed separately.
What Is a Projected RIT Score?
A projected RIT score estimates a future result based on the student’s starting score, the time between tests, and the applicable growth norms.
A projection is not a guarantee.
Actual results may differ because of:
- instruction;
- attendance;
- engagement;
- testing conditions;
- illness or fatigue;
- the time between administrations;
- ordinary measurement variation.
What Is a Score Range?
MAP reports may show a range around the reported RIT score.
This reflects measurement uncertainty. The reported score is an estimate of current achievement rather than a perfectly exact value.
Small differences between two tests should therefore be interpreted cautiously, especially when score ranges overlap.
What Are Goal Areas or Instructional Areas?
A MAP report may divide performance into broad goal areas or instructional areas.
Examples can include:
Mathematics
- number and operations;
- algebraic thinking;
- geometry;
- measurement and data;
- statistics and probability.
Reading
- foundational skills;
- vocabulary;
- literary text;
- informational text;
- comprehension and analysis.
Language Usage
- grammar and usage;
- mechanics;
- sentence construction;
- writing and revision.
The exact names depend on the assessment and standards alignment.
Goal-area information can help teachers identify possible priorities, but each area is based on fewer questions than the overall score and should not be treated as a complete diagnostic evaluation.
What Is a Good MAP Score?
There is no single MAP score that is good for every student.
Interpretation depends on:
- the subject;
- grade;
- testing season;
- current norms;
- previous scores;
- observed growth;
- classroom performance;
- the school’s purpose for testing.
An above-median percentile indicates above-median achievement in the applicable comparison group. It does not guarantee gifted identification, advanced placement, admission, or future academic success.
A below-median percentile does not prove that a student has a learning disability or cannot succeed.
Is There a MAP Passing Score?
There is no single national MAP Growth passing score.
A school or district may establish local criteria for:
- intervention;
- course placement;
- enrichment;
- programme eligibility;
- promotion decisions;
- additional assessment.
These local criteria should not be presented as universal NWEA pass marks.
Can a RIT Score Be Converted Into a Grade Level?
A RIT score should not be converted into a simple statement such as “the child is working at Grade 7 level.”
A student can show different strengths across domains within the same subject.
For example, one Math score may combine:
- strong geometry;
- average data skills;
- weaker fractions;
- emerging algebraic reasoning.
One overall RIT score cannot describe every skill equally.
How to Compare Two MAP Reports
Before comparing results, confirm that both scores represent:
- the same subject;
- compatible MAP Growth assessments;
- valid administrations;
- comparable testing seasons;
- appropriate time intervals;
- the same or clearly identified norm reference.
Then review:
- change in RIT score;
- score ranges;
- achievement percentile;
- growth percentile or projection;
- goal-area patterns;
- classroom evidence.
What If the Score Went Down?
A lower RIT score can reflect several possibilities, including:
- ordinary measurement variation;
- a short interval between tests;
- fatigue, illness, or distraction;
- rushing or rapid guessing;
- different testing conditions;
- a genuine change in measured achievement.
Ask whether the difference is larger than the expected score range and whether classroom performance shows a similar pattern.
One lower result should not automatically be treated as proof of lost learning.
What If Growth Is Below the Projection?
A projection is a planning reference rather than a guarantee.
Ask:
- Was the testing interval appropriate?
- Was the administration valid?
- Did the student receive the expected instruction?
- Which goal areas changed?
- Does classroom work show the same concern?
- What support or monitoring will follow?
How Parents Should Read the Report
When the school permits practice, families can review TestPrep-Online MAP practice or compare options with MAP Shop. Confirm the grade or level, current pack contents, access terms, and school policy before purchasing.
A useful order is:
- Confirm the subject and testing date.
- Find the RIT score.
- Review the score range.
- Find the achievement percentile.
- Review growth separately.
- Examine goal areas.
- Compare with previous reports.
- Ask how the school will use the information.
Questions to Ask the Teacher
- Which MAP Growth assessment did my child take?
- Which norms were used?
- What does the RIT score show?
- Is the percentile based on the current testing season?
- Is the score change larger than expected measurement variation?
- Which goal areas are relative strengths?
- Which areas need additional instruction?
- Does the result match classroom performance?
- What growth target is being used?
- When will the next assessment occur?
- What instructional action will follow?
