NWEA Map Score Charts and i-Ready Score Charts 2027-2028 – Updated Norms
iReady Inform and NWEA MAP Score Charts 2027–2028: Scores, Norms, Percentiles and Grade Levels
If you are looking for iReady Inform scores for 2027–2028, an i-Ready Diagnostic score chart, or the latest NWEA MAP score charts, this guide brings the main information together in one place.
The most important iReady change is the transition from the familiar i-Ready Diagnostic name to i-Ready Inform. Although parents and teachers will increasingly see the new iReady Inform name during the 2027–2028 school year, millions of searches, older school reports and existing resources still refer to the assessment as i-Ready Diagnostic.
For that reason, this guide uses both names.
NWEA MAP Growth has not undergone the same type of name change. It continues to report achievement using the RIT scale, with national percentile interpretation based on the latest published MAP Growth norms.
Below you will find iReady Reading and Math score references, NWEA MAP Reading, Math, Science and Language Usage score charts, explanations of percentiles and placement levels, and links to more detailed score tables at ReadyScores.com and SchoolTest.org.
iReady Diagnostic Is Now Called iReady Inform
The assessment parents have known for years as i-Ready Diagnostic is transitioning to the name i-Ready Inform.
This is important when searching for scores because an older school report might say “i-Ready Diagnostic,” while newer resources and reports increasingly use “i-Ready Inform.”
The change does not mean that iReady suddenly became an entirely unrelated assessment.
iReady Inform continues to help schools measure:
- Reading achievement
- Math achievement
- National percentile standing
- Grade-level placement
- Student growth
- Strengths and learning needs
For a complete introduction to both names, see the main i-Ready Diagnostic scores and iReady Inform score guide at ReadyScores.com.
You can also read SchoolTest’s explanation of iReady Inform scores by grade and the transition from i-Ready Diagnostic.
What Changed From i-Ready Diagnostic to iReady Inform?
The name change is accompanied by changes intended to make the assessment experience shorter while continuing to provide Reading and Math achievement information.
The major points for parents are:
- i-Ready Diagnostic is becoming iReady Inform.
- Reading and Mathematics remain the primary subjects.
- The assessment remains adaptive.
- Scale scores continue to be reported.
- National percentile information remains important.
- Grade-level placement remains part of score interpretation.
- Growth remains a major part of the assessment.
Parents should therefore not discard older i-Ready Diagnostic reports. They can still provide valuable information about a child’s previous performance and academic growth.
iReady Inform vs i-Ready Diagnostic
| Feature | i-Ready Diagnostic | iReady Inform 2027–2028 |
|---|---|---|
| Assessment name | i-Ready Diagnostic | iReady Inform |
| Reading assessment | Yes | Yes |
| Math assessment | Yes | Yes |
| Adaptive testing | Yes | Yes |
| Scale scores | Yes | Yes |
| National percentiles | Yes | Yes |
| Placement levels | Yes | Yes |
| Growth information | Yes | Yes |
| Testing experience | Original Diagnostic format | Shorter updated assessment experience |
Are iReady Score Charts Changing for 2027–2028?
A new school year does not automatically mean an entirely new set of national iReady norms.
National norms are normally used for multiple school years until Curriculum Associates determines that an updated national comparison is warranted.
Therefore, parents searching for an iReady score chart 2027–2028 should use the latest published score and percentile references rather than assuming every score needs to increase simply because the calendar year has changed.
See the full i-Ready Diagnostic score chart for Reading in 2027–2028 as published at ReadyScores.com for detailed Reading scores by grade, season and percentile.
For Mathematics, see the complete i-Ready Diagnostic score chart in Math for 2027–2028 at ReadyScores.com.
iReady Inform Reading Score Chart 2027–2028
The iReady Reading scale changes substantially as children progress through school.
A score that is above average for Grade 2 would obviously have a very different meaning for a student in Grade 7.
Testing season matters as well.
A Fall score should be compared with Fall norms, while a Spring score should be interpreted against Spring expectations.
| Grade | Fall 50th Percentile | Winter 50th Percentile | Spring 50th Percentile |
|---|---|---|---|
| Kindergarten | 341 | 371 | 401 |
| Grade 1 | 403 | 424 | 454 |
| Grade 2 | 460 | 489 | 505 |
| Grade 3 | 502 | 522 | 534 |
| Grade 4 | 533 | 548 | 558 |
| Grade 5 | 558 | 570 | 579 |
| Grade 6 | 573 | 582 | 590 |
| Grade 7 | 590 | 602 | 609 |
| Grade 8 | 607 | 616 | 622 |
The table above provides a quick midpoint reference. It should not be interpreted as a pass/fail chart.
For the complete percentile tables, visit the full iReady Diagnostic Reading score chart by grade and percentile.
ReadyScores provides much more detail than the simplified table above, making its i-Ready Diagnostic scores by grade Reading chart particularly useful when you already know the exact score from a child’s report.
SchoolTest also maintains an alternative iReady Diagnostic Reading scores by grade-level chart.
If you specifically need percentiles, see the i-Ready Diagnostic Reading percentile score chart for grades K–8.
iReady Inform Math Score Chart 2027–2028
Math scores use a different scale pattern from Reading, so parents should always use a dedicated iReady Math score chart.
| Grade | Fall 50th Percentile | Winter 50th Percentile | Spring 50th Percentile |
|---|---|---|---|
| Kindergarten | 342 | 360 | 378 |
| Grade 1 | 376 | 393 | 407 |
| Grade 2 | 402 | 418 | 434 |
| Grade 3 | 428 | 444 | 458 |
| Grade 4 | 452 | 465 | 479 |
| Grade 5 | 470 | 480 | 490 |
| Grade 6 | 483 | 490 | 497 |
| Grade 7 | 493 | 499 | 504 |
| Grade 8 | 501 | 506 | 512 |
To compare an individual score against the full percentile ranges, see the complete i-Ready Diagnostic Math score chart for grades K–8.
If you are specifically researching the 2027–2028 school year, use the iReady Diagnostic score chart in Math with grade-level and percentile references at ReadyScores.
SchoolTest provides another useful reference in its i-Ready Diagnostic Math scores by grade-level chart.
iReady Diagnostic Scores by Grade
One of the most important rules when interpreting iReady results is to compare a child with the correct grade.
An iReady Diagnostic score by grade is much more meaningful than a raw score without context.
You should always identify:
- The student’s grade
- Reading or Math
- Fall, Winter or Spring testing season
- The scale score
- The corresponding percentile
- The placement level
ReadyScores combines these measurements in its iReady Diagnostic scores by grade and iReady Inform results guide.
SchoolTest also provides a combined i-Ready Diagnostic scores by grade chart for Math and Reading.
What Is a Good iReady Diagnostic Score?
There is no single “good iReady score” for every student.
A good score for a Grade 1 student cannot be compared directly with the score expected from a Grade 6 student.
The testing season also changes the comparison.
To understand whether a result is average, above average or below average, read the iReady score chart by grade explaining what counts as a good i-Ready Diagnostic score.
For another interpretation, SchoolTest explains what is a good i-Ready Diagnostic score by grade in Math and Reading.
Use the iReady Score Calculator
If you already have a child’s scale score, manually searching a large chart may not be necessary.
Use the free iReady Diagnostic score calculator for percentile and grade-level interpretation.
The calculator is designed to help put an iReady score into context using the student’s subject, grade and testing season.
Track iReady Inform Growth
A score chart shows where a student performed at one particular point in time.
For many families, growth is equally important.
A student who starts below average but makes substantial progress during the year may be showing very positive academic development.
Use the iReady Diagnostic and iReady Inform growth tracker for Fall, Winter and Spring scores to compare multiple testing periods.
iReady Placement Levels Explained
Percentiles and placement levels are not the same thing.
An iReady report may describe a student as:
- Above Grade Level
- Mid or Late On Grade Level
- Early On Grade Level
- One Grade Level Below
- Two or More Grade Levels Below
These categories are based on grade-level skill expectations rather than simply the student’s national percentile.
See the complete iReady Diagnostic placement levels chart and explanation for more information.
iReady Levels AA, A, B, C, D, E, F, G and H
Parents also encounter letter levels in some iReady resources.
These should not be confused with percentile scores.
The iReady Levels AA through H grade-level guide explains how these levels are commonly interpreted.
SchoolTest has an additional guide explaining what grade Levels D, E, F, G and H represent in iReady Diagnostic.
What If My Child’s iReady Diagnostic Score Is Below Grade Level?
One below-grade result should be looked at in context.
Parents should consider:
- The child’s previous score
- Growth since the last assessment
- Individual Reading or Math domains
- Classroom grades
- Teacher observations
- Whether the child was tired, distracted or anxious during testing
If your child’s report shows a lower placement, read the detailed ReadyScores guide on what an i-Ready Diagnostic score below grade level means for parents.

NWEA MAP Score Charts 2027–2028
NWEA MAP Growth uses a different score scale from iReady.
MAP Growth results are reported using RIT scores.
These scores are designed to make it possible to follow academic achievement and growth over time.
Parents should never compare an iReady scale score directly with an NWEA MAP RIT score.
For the main reference, see the complete NWEA MAP score chart by grade level at ReadyScores.com.
What NWEA MAP Norms Apply in 2027–2028?
The current national reference is based on NWEA’s latest MAP Growth norm study.
A new school year does not automatically create new NWEA MAP norms.
Unless NWEA publishes another national norm update before or during the 2027–2028 school year, the latest published national norms remain the appropriate reference.
This is why a page labeled NWEA MAP scores 2027–2028 can legitimately use the current MAP Growth norms rather than artificially changing the scores every year.
NWEA MAP Reading Score Chart 2027–2028
The following table gives a quick national midpoint reference for MAP Reading.
| Grade | Fall Reading | Winter Reading | Spring Reading |
|---|---|---|---|
| Kindergarten | 138 | 146 | 152 |
| Grade 1 | 155 | 163 | 168 |
| Grade 2 | 170 | 177 | 182 |
| Grade 3 | 185 | 190 | 194 |
| Grade 4 | 196 | 199 | 202 |
| Grade 5 | 204 | 206 | 208 |

NWEA MAP Scores by Grade Level
Just like iReady, MAP scores cannot be interpreted properly without the student’s grade.
The most useful resources therefore organize NWEA MAP scores by grade level.
Start with the NWEA MAP scores by grade level and percentile chart at ReadyScores.
SchoolTest also provides a detailed NWEA MAP score chart by grade level for Reading and Math.
For seasonal comparisons, the NWEA MAP scores by grade Fall, Winter and Spring chart is particularly useful.
What Is a Good NWEA MAP Score?
There is no universal good MAP score.
A RIT score must be interpreted according to:
- Grade
- Subject
- Testing season
- National percentile
- Previous achievement
- Academic growth
ReadyScores explains these comparisons in its guide to what is a good NWEA MAP score by grade level.
NWEA MAP Score Calculator
If you already know the student’s RIT score, use the NWEA MAP score calculator for grade-level and percentile interpretation.
This can be quicker than manually searching the full NWEA MAP score chart.
What Changed With the Latest NWEA MAP Norms?
The most recent major MAP norms update changed the national comparison population.
It did not simply reset the RIT scoring scale.
This means that the same RIT score can remain comparable while the percentile associated with that score changes slightly as national achievement patterns change.
SchoolTest explains these changes in the new NWEA MAP norms and score chart by grade-level guide.
You can also review the updated NWEA MAP scores by grade following the latest norm changes.
NWEA MAP Achievement vs Growth
One important benefit of MAP Growth is that the report looks at more than achievement.
Achievement tells you how a student currently compares with other students.
Growth tells you how much academic progress the student has made.
For example, a student could be:
- At the 30th percentile but showing very strong growth
- At the 80th percentile but showing relatively little growth
- Near the national average and growing approximately as expected
This is why parents should not judge a MAP report only by the raw RIT score.

iReady Inform vs NWEA MAP Growth
| Feature | iReady Inform / Diagnostic | NWEA MAP Growth |
|---|---|---|
| Main score | iReady scale score | RIT score |
| Reading | Yes | Yes |
| Math | Yes | Yes |
| Science | Not a primary Inform assessment | Yes |
| Language Usage | Not a separate primary assessment | Yes |
| National percentiles | Yes | Yes |
| Adaptive testing | Yes | Yes |
| Growth reporting | Yes | Yes |
An iReady Diagnostic score chart should never be used to interpret an NWEA MAP score.
Likewise, an NWEA MAP score chart cannot be used to interpret an iReady Inform result.
They are separate assessments with separate scoring systems.
Why Fall, Winter and Spring Score Charts Matter
Both iReady and NWEA MAP commonly test students more than once during the academic year.
The most common testing periods are:
- Fall
- Winter
- Spring
Students are expected to learn between these testing windows, so the national comparison changes throughout the year.
This means you should always use an i-Ready Diagnostic score chart or NWEA MAP score chart that corresponds with the correct testing season.
Do iReady and NWEA MAP Scores Change Every Calendar Year?
No.
A student does not need a higher score simply because the calendar changes from 2027 to 2028.
The important factors are grade, testing season and the current national norm set.
If national norms do not change, the same score tables can remain appropriate across multiple school years.
2027–2028 iReady and MAP Norm Status
| Assessment | Current Reference | Separate 2027–2028 Norms? |
|---|---|---|
| iReady Inform Reading | Current iReady national norms | No separate annual norm set announced |
| iReady Inform Math | Current iReady national norms | No separate annual norm set announced |
| NWEA MAP Reading | Latest MAP Growth national norms | No newer annual norm set announced |
| NWEA MAP Math | Latest MAP Growth national norms | No newer annual norm set announced |
| NWEA MAP Science | Latest MAP Growth national norms | No newer annual norm set announced |
| NWEA MAP Language Usage | Latest MAP Growth national norms | No newer annual norm set announced |
