How to Read CogAT Scores: SAS, Percentile Rank, Stanine & Ability Profile Explained（2026）

Your child’s CogAT score report may include several numbers—Raw Score, USS, SAS, Percentile Rank, and Stanine—and each one tells you something different. Many parents open the report and immediately wonder what the scores mean, whether they are high, and how they relate to gifted-program decisions.

This guide explains how to read each score, understand the Ability Profile, interpret high scores, and understand what CogAT results may mean for gifted-program identification. It is written for U.S. parents who want clear, practical answers based on how the test is scored by Riverside Insights, including the 2024 post-pandemic norms now in use.

Quick Summary: What Do CogAT Scores Mean?

CogAT scores show how a student’s reasoning performance compares with students in a relevant age or grade norm group. The test measures reasoning abilities across verbal, quantitative, and nonverbal domains rather than academic achievement or IQ.

How to Read Your CogAT Score Report

1. Raw Score vs. USS

Raw Score is simply the number of questions your child answered correctly. It is the starting point of the scoring process.

USS (Universal Scale Score) is a continuous growth scale that runs from kindergarten through Grade 12. The testing company uses the USS to convert a student’s performance into the more familiar scores you see on the report (SAS, percentile rank, and stanine).

The basic flow is:

Raw Score → USS → SAS / Percentile Rank / Stanine

Raw Score and USS are not the same thing. A higher raw score generally produces a higher USS, but the conversion also accounts for the difficulty of the form and the student’s age or grade. You will almost never need to interpret the raw score or USS by themselves; the derived scores are the ones that matter for understanding relative performance.

2. SAS (Standard Age Score)

What is SAS? The Standard Age Score is a standardized score that places your child’s performance on a common scale based on age.

Why is 100 average? The SAS is scaled so that the average score for the norm group is 100, with a standard deviation of 16. On Forms 7 and 8, the reported range is typically 50–160.

What is considered a high SAS? A SAS of 100 represents average performance for the norm group. Scores above 100 indicate stronger performance relative to same-age peers. Scores in the 120s and higher are generally considered well above average; scores approaching or exceeding 130–140 are very high. Because the scale is continuous, small differences near the top of the distribution can still reflect meaningful differences in performance.

3. PR (Percentile Rank): The Most Common Source of Confusion

A percentile rank is not the percentage of questions your child answered correctly.

A 95th percentile score means the student’s performance was higher than that of approximately 95% of students in the relevant comparison group; it does not mean the student answered 95% of the questions correctly.

Percentile rank answers the question: “Compared with whom?” Your report may show:

• Age Percentile Rank (compared with students of the same age)
• Grade Percentile Rank (compared with students in the same grade)
• Local Percentile Rank (compared with students in the local norm group, when available)

Always check which norm group is being used. A score that looks high against a national age group may look different against a local or grade-level group, and vice versa. The percentile rank is one of the most useful numbers on the report because it directly communicates relative standing.

4. Stanine: What Does a 1–9 Score Mean?

Stanine scores compress performance into nine broad bands. They are useful for a quick overview but less precise than percentile ranks.

Stanine is a broad score band, so the percentile rank provides more detail. Two students in the same stanine can still differ by a meaningful number of percentile points.

Understanding the CogAT Ability Profile

What Is a CogAT Ability Profile?

An Ability Profile summarizes both the student’s overall level of performance and the pattern of strengths and weaknesses across the Verbal, Quantitative, and Nonverbal batteries. It is designed to give teachers and parents a compact view of relative strengths rather than a single overall number.

How to Read a Profile Like 7B(N+)

A typical profile such as 7B(N+) breaks down into three parts:

• 7 — The overall level, based on the median stanine of the three batteries. A 7 indicates above-average overall performance.
• B — The letter describes the pattern of differences among the three batteries. Letter codes indicate whether one or more batteries stand noticeably above or below the others.
• (N+) — The symbol in parentheses shows a relative strength (or weakness). In this example, Nonverbal is a relative strength compared with the student’s other CogAT batteries.

The profile does not mean the Nonverbal score is “gifted” in isolation. It simply flags that Nonverbal reasoning is relatively stronger than the student’s Verbal and Quantitative results on this particular administration.

What Do A, B, C, E, + and − Mean?

• A — All three batteries are relatively similar (flat profile).
• B — One battery is relatively higher or lower than the other two.
• C — Two batteries differ from the third in a more complex pattern.
• E — Extreme differences among batteries (used less frequently; at least two scores differ by 24 or more SAS points).
• + — Relative strength in the indicated battery.
• − — Relative weakness in the indicated battery.

These codes help highlight patterns that a single composite score can hide. A student with an average composite may still show a clear relative strength in one domain that is useful for instructional planning.

Gifted CogAT Score Chart: What Percentile Is Considered Gifted?

There is no single nationwide CogAT score that guarantees admission to a gifted program. Scores at or above the 95th–97th percentile are often considered very high and may be relevant to gifted identification, but eligibility criteria vary by district and program.

These ranges are reference points, not universal gifted-program cutoffs.

Is 95th or 97th Percentile Gifted?

It can support gifted identification, but it does not automatically qualify a child for a gifted program. Districts typically look at multiple pieces of evidence, which may include:

• CogAT scores
• Teacher recommendation
• Achievement test results
• Classroom performance
• Other screening measures
• Local eligibility criteria

A high CogAT percentile is often one important data point among several.

Why Gifted Cutoffs Vary by School District

There is no single nationwide CogAT cutoff. One district may use the 95th percentile as a screening threshold, while another may require a higher score or combine CogAT results with additional evidence. Local norms, program capacity, and state or district policy all influence the final decision. Always check the specific criteria published by your school or district rather than assuming a national standard applies.

Common Mistakes When Reading CogAT Scores

Mistake 1 Thinking the 95th percentile means 95% correct. Percentile rank reflects relative standing, not the percentage of items answered correctly.

Mistake 2 Treating Raw Score, USS, SAS, and PR as interchangeable. Each score serves a different purpose in the conversion process. The percentile rank and SAS are usually the most useful for parents.

Mistake 3 Assuming a high CogAT score guarantees gifted placement. Eligibility depends on local criteria and often includes multiple measures.

Mistake 4 Averaging percentile ranks to calculate a composite score. Parents should not simply average percentile ranks to recreate a composite SAS. Official composite and partial-composite scores are derived from the USS and then converted; they are not simple averages of the three percentile ranks.

Next Steps for Parents

If Your Child Has a High CogAT Score

1. Check the percentile and the specific norm group (age, grade, or local).
2. Review the individual Verbal, Quantitative, and Nonverbal batteries.
3. Read the Ability Profile for patterns of relative strength.
4. Check your district’s gifted identification criteria.
5. Ask the teacher or gifted coordinator what additional evidence is considered.

If Your Child Has an Average Score

A CogAT score is one measure of reasoning performance, not a complete description of a child’s potential. Look at the battery pattern, classroom performance, and other indicators of strength. Talk with the teacher about areas where your child shows interest or aptitude. Many students who score near the average overall still have relative strengths that can be supported through differentiated instruction.

If One Battery Is Much Higher or Lower

Do not look only at the composite. A student may show a relative strength in Nonverbal reasoning even when the overall score is closer to average. The Ability Profile is specifically designed to surface these patterns so that instruction can build on strengths and address relative weaknesses.

Frequently Asked Questions

What is a good CogAT score?

A good CogAT score depends on the context. Scores at or above the 75th–90th percentile are generally above average. Scores at the 95th percentile and higher are considered very high relative to the norm group.

Is a 95th or 97th percentile CogAT score gifted?

It can support gifted identification, but it does not automatically qualify a child for a gifted program. Districts set their own thresholds and usually consider multiple measures such as teacher recommendations, achievement tests, and classroom performance.

What does 7B(N+) mean on CogAT?

The 7 indicates an above-average overall level (median stanine). The B shows a pattern in which one battery differs from the others. The (N+) indicates that Nonverbal is a relative strength compared with the student’s other batteries.

Is CogAT an IQ test?

No. CogAT measures reasoning abilities in verbal, quantitative, and nonverbal domains. It is not designed or scored as an IQ test.

Can a child be gifted without a very high CogAT score?

Yes. Gifted identification is almost always multi-faceted. Classroom performance, achievement data, teacher input, and other assessments can all contribute. A moderate CogAT score does not rule out giftedness if other evidence is strong.

Conclusion

Understanding your child’s CogAT scores starts with knowing what each number represents, how percentile rank differs from percentage correct, and how the Ability Profile highlights patterns across batteries. Once you have that foundation, the next step is to place the results in the context of your district’s criteria and your child’s broader academic picture. Clear interpretation of the report helps you ask better questions of teachers and gifted coordinators and support your child’s learning strengths.
