Your child\u2019s CogAT score report may include several numbers\u2014Raw Score, USS, SAS, Percentile Rank, and Stanine\u2014and 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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

<\/span>Quick Summary: What Do CogAT Scores Mean?<\/span><\/h2>\n\n\n\n

CogAT scores show how a student\u2019s 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.<\/p>\n\n\n\n

<\/span>How to Read Your CogAT Score Report<\/span><\/h2>\n\n\n\n

1. Raw Score vs. USS<\/h3>\n\n\n\n

Raw Score<\/strong> is simply the number of questions your child answered correctly. It is the starting point of the scoring process.<\/p>\n\n\n\n

USS (Universal Scale Score)<\/strong> is a continuous growth scale that runs from kindergarten through Grade 12. The testing company uses the USS to convert a student\u2019s performance into the more familiar scores you see on the report (SAS, percentile rank, and stanine).<\/p>\n\n\n\n

The basic flow is:<\/p>\n\n\n\n

Raw Score \u2192 USS \u2192 SAS \/ Percentile Rank \/ Stanine<\/p>\n\n\n\n

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\u2019s 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.<\/p>\n\n\n\n

2. SAS (Standard Age Score)<\/h3>\n\n\n\n

What is SAS?<\/strong> The Standard Age Score is a standardized score that places your child\u2019s performance on a common scale based on age.<\/p>\n\n\n\n

Why is 100 average?<\/strong> 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\u2013160.<\/p>\n\n\n\n

What is considered a high SAS?<\/strong> 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\u2013140 are very high. Because the scale is continuous, small differences near the top of the distribution can still reflect meaningful differences in performance.<\/p>\n\n\n\n

3. PR (Percentile Rank): The Most Common Source of Confusion<\/h3>\n\n\n
\n
\"Side-by-side<\/figure><\/div>\n\n\n

A percentile rank is not the percentage of questions your child answered correctly.<\/strong><\/p>\n\n\n\n

A 95th percentile score means the student\u2019s 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.<\/p>\n\n\n\n

Percentile rank answers the question: \u201cCompared with whom?\u201d Your report may show:<\/p>\n\n\n\n
