The ISEE score report arrives and you open it expecting clarity. Instead, you get a page full of numbers: scaled scores, percentile ranks, stanines, and something called a "stanine analysis" with bar graphs. None of it comes with a passing grade or a simple "your child did well."
That's by design. The ISEE isn't a pass/fail test — it's a comparison tool. Every number on the report tells you how your child performed relative to other students who took the same test. Understanding what each number means (and which ones actually matter) can turn a confusing page of data into a useful guide for next steps.
What's on the Score Report
Your child's ISEE score report contains results for four scored sections and one unscored section:
| Section | Scored? | What It Tests |
|---|---|---|
| Verbal Reasoning | Yes | Vocabulary (synonyms) and logic (sentence completions) |
| Quantitative Reasoning | Yes | Mathematical reasoning and problem-solving |
| Reading Comprehension | Yes | Understanding written passages |
| Mathematics Achievement | Yes | Grade-level math skills and procedures |
| Essay | No | Writing ability — sent to schools but not scored by ERB |
For each scored section, the report shows three numbers: a scaled score, a percentile rank, and a stanine. Let's break down what each one means.
Scaled Scores: The Raw Number
The scaled score is a number between roughly 760 and 940 (the exact range varies by test level). It's calculated from the number of questions your child answered correctly, adjusted for difficulty.
Here's what most parents miss: scaled scores are nearly useless on their own. A score of 880 in Verbal Reasoning doesn't mean your child got 88% right, and it can't be directly compared to an 880 in Math Achievement. The scales are different across sections and across test administrations.
Scaled scores exist mainly so ERB can compute percentiles and stanines. You can note them, but don't spend time trying to interpret them.
Percentile Ranks: Where Your Child Stands
The percentile rank tells you what percentage of students in the comparison group scored at or below your child's level. A percentile rank of 72 means your child scored as well as or better than 72% of the comparison group.
Two critical details about percentiles:
The comparison group is norm-referenced. Your child isn't being compared to every student in the country — they're compared to other students who took the ISEE at the same level during a recent norming period. These are typically students applying to competitive private schools, so the comparison pool is already above-average academically. A 50th percentile on the ISEE does not mean "average student." It means average among private school applicants.
Percentiles aren't linear. The difference between the 50th and 60th percentile is much smaller than the difference between the 90th and 99th percentile. Most students cluster in the middle of the bell curve, so a few extra correct answers near the 50th percentile can jump you 10 percentile points. Near the top, every percentile point represents significantly more distance.
Stanines: The Number Schools Care About
The stanine is the score that matters most to admissions offices. It converts your child's percentile rank into a single digit from 1 to 9:
| Stanine | Percentile Range | Category |
|---|---|---|
| 9 | 96--99 | Very high |
| 8 | 89--95 | High |
| 7 | 77--88 | Above average |
| 6 | 60--76 | Slightly above average |
| 5 | 40--59 | Average |
| 4 | 23--39 | Slightly below average |
| 3 | 11--22 | Below average |
| 2 | 4--10 | Low |
| 1 | 1--3 | Very low |
Schools use stanines because they're stable and simple. A child scoring at the 74th percentile one day and the 78th percentile the next gets a stanine of 6 both times. The stanine absorbs normal test-day variation and gives admissions teams a reliable category to work with.

The Stanine Analysis: Reading the Bar Graph
Below the section scores, you'll find a stanine analysis — a bar graph that breaks each section into more specific skill areas. This is the most actionable part of the entire report, and most families skip right past it.
For example, the Quantitative Reasoning stanine analysis might show separate bars for:
- Number concepts and operations
- Algebraic concepts
- Geometric concepts
- Measurement and data analysis
If your child scored a stanine 6 overall in Quantitative Reasoning but the bar graph shows a stanine 4 in algebraic concepts and a stanine 8 in number operations, you now know exactly where to focus. The overall stanine hides a specific weakness that targeted practice can fix.
How to use it:
- Look for any skill area where the bar is two or more stanines below the section average
- Those are your priority study areas
- Skill areas at or above the section average don't need extra attention
- If all skill areas are roughly equal, the section score reflects consistent performance — improvement will come from general practice rather than targeting one topic
This analysis is especially useful when planning follow-up prep. Instead of "study more math," you can say "spend two weeks on algebra word problems." That specificity makes study time far more productive.
The Essay: Unscored but Not Unread
The essay section doesn't receive a stanine or percentile. ERB doesn't score it at all. Instead, a copy of your child's essay is sent directly to every school that receives the score report.
This means the essay is simultaneously the lowest-stakes and highest-stakes part of the test. It can't hurt your child's scores, but a poorly written or off-topic essay gives admissions officers a negative data point that numbers can't override.
Schools look for age-appropriate writing: clear organization, specific details, and a genuine voice. They're not expecting polished prose — they're looking for evidence that your child can think and communicate on paper. Learn more about what schools see in the essay.
How Schools Use the Score Report
Different schools weigh ISEE scores differently, but here's the general pattern:
Highly selective schools (acceptance rates below 20%) typically look for stanines of 7--9 across all sections. A stanine of 5 or 6 in one section won't automatically disqualify your child, but it means other parts of the application need to be strong.
Moderately selective schools generally consider stanines of 5--6 as acceptable, with 7+ being competitive. These schools weigh the full application more evenly — grades, recommendations, interview, and test scores all factor in.
Less selective schools may accept stanines of 4--5, using the ISEE more as a placement tool than an admissions filter. They're looking at where to put your child academically, not whether to admit them.
No school publishes minimum stanine requirements. Admissions is holistic. But knowing the general expectations helps you interpret your child's scores in context.
What to Do With the Results
If the scores are where you expected
Great. Send the report to your target schools and move on to the rest of the application. No additional testing needed.
If one section is significantly lower than the others
Look at the stanine analysis bars for that section. Identify the weak skill area, then target it with focused practice. If your child is eligible to retest (you can take the ISEE once per testing window — see retake rules), consider scheduling a second attempt after four to six weeks of targeted study.
A child who scored a stanine 4 in Reading Comprehension but stanine 7 everywhere else likely has a specific, fixable gap — not a general testing problem.
If the scores are uniformly lower than expected
Don't panic. A few possibilities:
- Test-day factors — illness, anxiety, poor sleep. These are real and significant. If your child was off that day, the scores may not reflect their ability.
- The comparison group is strong. Remember, ISEE percentiles compare your child to other private school applicants, not the general population. A "below average" ISEE score still represents solid academic performance.
- Preparation gaps. If your child took the test with minimal prep, a structured study plan and a retake can yield meaningful improvement. Use the stanine analysis to direct your study time.
If you're considering a retake
Use the score report as your study guide. The stanine analysis tells you exactly what to work on. Spend four to six weeks targeting the weakest skill areas, take a few practice tests to confirm improvement, then schedule the retake.
Don't retake the test without changing your preparation approach. Taking the same test with the same prep will produce the same scores.
Score Report FAQ
Can I choose which scores to send to schools? No. When you register for the ISEE, you select which schools receive the report. ERB sends scores to all selected schools automatically. You cannot suppress scores from a particular test date. This is why many families choose to test early and retake if needed — the later scores go to schools, not the earlier ones.
How long until scores are available? ERB typically releases scores within 7--10 business days of the test date. You'll receive an email notification when the report is ready in your ERB account.
Do schools see all my child's ISEE scores? Schools receive the scores from the test dates you designate during registration. If your child takes the ISEE multiple times and you select different school lists each time, a school on the second list only sees the second set of scores.
What if my child's percentile seems too low? Remember the comparison group. A 40th percentile on the ISEE might correspond to well above grade level nationally. The ISEE norm group is self-selected — these are students motivated enough to apply to competitive schools. Use our score calculator to put the numbers in context.
Do stanines change between testing windows? Yes. ERB periodically re-norms the test, which can shift the percentile-to-stanine boundaries slightly. A raw performance that earned a stanine 7 in one norming period might earn a 6 or 8 in another. The shifts are small, but they're why you shouldn't over-interpret a single stanine.
The Bottom Line
Your child's ISEE score report is a tool, not a verdict. The stanines tell schools where your child stands academically. The stanine analysis tells you where to focus if improvement is needed. The essay gives schools a window into your child's thinking.
Read the report once for the overall picture, then zoom into the stanine analysis for specifics. If the scores don't match expectations, use the analysis to build a targeted study plan rather than guessing at what went wrong.
