Read an i-Ready report in this order: testing context, scale score, placement, domains and growth goals. No single number tells the whole story. The report helps families and teachers identify strengths, choose a priority and monitor progress; it is not a classroom grade.
Beginning in 2026–27, i-Ready Diagnostic is called i-Ready Inform. Schools may use either name during the transition, but the core reports and interpretation principles remain familiar.
The five main parts of an i-Ready report
| Report field | Question it answers |
|---|---|
| Scale score | What score did the student earn on a common scale? |
| Placement | How does performance relate to grade-level expectations? |
| Domains | Which skill areas are stronger or need support? |
| Percentile rank | How does the score compare with a national sample? |
| Growth goals | What progress is the student working toward? |
1. Start with the testing context
Confirm the subject, grade, testing window and date. Reading and Mathematics are separate, and placement ranges can depend on grade and season. Compare like with like—for example, fall Reading with a later Reading administration.
2. Read the scale score
The scale score uses a consistent measurement scale so educators can examine change across administrations. It is not a percentage correct or a letter grade. Interpret it with the student’s grade, testing window, placement and previous results.
3. Check the placement level
Placement is criterion referenced: it describes performance against grade-level expectations. Reports may show categories such as above grade level, on grade level, one grade level below, or two or more grade levels below. Treat the label as a starting point for support, not a permanent description of ability.
4. Study the domain results
Domains provide useful instructional detail. Reading may include phonological awareness, phonics, vocabulary and comprehension; Mathematics may include number and operations, algebraic thinking, measurement and geometry. A student can have a strong overall result while still needing help in one area.
5. Understand percentile rank
If shown, percentile rank compares the student with a nationally representative group in the same grade and testing season. A percentile rank of 60 means the score was as high as or higher than 60 percent of that comparison group. It does not mean the student answered 60 percent of questions correctly.
6. Compare Typical Growth and Stretch Growth
Typical Growth is a realistic annual target informed by how similar students have grown. Stretch Growth is an ambitious but attainable target toward proficiency. Check points gained and the percentage of each goal reached. Goals are individualized, so do not compare targets between children.
How parents should interpret the report
- Celebrate one strength. Name a domain or improvement.
- Select one priority. Focus on the clearest skill need.
- Look for a trend. Compare testing windows and classroom evidence.
- Ask for the teaching plan. Agree on appropriate school and home support.
- Review later. Set a date to discuss progress.
If a result unexpectedly falls, testing conditions, stress, distraction or rushing may matter. Read our explanation of why an i-Ready score can go down.
What the report cannot tell you alone
An i-Ready result is one source of evidence. It cannot independently explain motivation, creativity, language background, test anxiety or every classroom skill. Teachers should combine it with observations, assignments, quizzes and other assessments. Avoid using a single score to label a child or make a high-stakes decision without broader evidence.
Frequently asked questions
What is a good i-Ready score?
There is no universal “good” number for every student. Interpret the scale score using grade, subject, season, placement and growth from the student’s own starting point.
Is placement the same as the student’s classroom grade?
No. Placement describes assessed performance relative to grade-level expectations; it does not change enrollment or replace teacher judgment.
The bottom line
Read an i-Ready report as a connected story: context explains the test, the scale score tracks performance, placement adds grade-level meaning, domains identify skills and growth goals point forward. For the 2026–27 naming update, see i-Ready Inform vs i-Ready Diagnostic.
