CogAT Scores – Understand Your Child’s CogAT Test Results

CogAT scoring is based on your child’s age (not grade level). Your child will receive what’s called an SAS, or “Standard Age Score,” which compares your child’s score against other children in the same age range. The highest SAS that a child can receive on the CogAT® is 160, while 100 is considered to be an average score.

Here are all the steps used to calculate a child’s unique test score:

  • Raw Score. This is total number of questions answered correctly; however, incorrect answers do not cause points to be deducted from the overall raw score.
  • Universal Scale Score (USS). After the Raw Score is determined, it’s converted to a normalized standard score known as the Universal Scale Score. There are separate USS scores for each of the test’s three verbal, nonverbal and quantitative reasoning skills subsections (also called “batteries”). The Composite USS is determined by averaging these three different scores.
  • Standard Age Score (SAS). The Standard Age Score has a maximum possible score of 160; the average score is 100.
  • Percentile Rank (PR). School districts use this number to compare students that share the same age and grade level. A percentile rank of 80 means that child’s score was higher than 80% of students who took the same test. The average percentile rank is 50.
  • Stanine (S). A stanine is a very broad, simplified score ranging from 1 (lowest) to 9 (highest possible), and it’s normalized for the child’s age and grade level.

CogAT Score Report
Each stanine is made up of a range of percentile ranks. The table below shows the percentile ranks that formulate each stanine and the associated ability level.

You noted that the highest possible SAS score on the Cogat is 160. How can one explain a child scoring higher than 160?

Hongjin Qiu says:

My kid has a score of 9E(v-) for the second grade. How is the explaination of the score? High or low? She is 8 years old.

Meg says:

go to cogat.com for interpretation, 9E means that there might be an error or there is an extreme difference between verbal, nonverbal, etc. 9 is the highest achievement level with 9A being the highest possible

Agnes Trzesniowski says:

My daughter’s score is 7C(V+).
May you please help me interpret.

Mary says:

My child scored 8A. Please help me to interpret that. Thank you.

Do you take into account personality and interests, likes/dislikes? Ability to communicate with adults and other children? Passions? Empathy? This is the most cookie cutter approach to understanding a child’s intellect that I’ve ever seen.

TestingMom.com says:

Hi Julie – the CogAT test doesn’t assess the child’s EQ (emotional intelligence). It’s based solely on the cognitive ability of the child.

what does it mean when your childs score is unavailable because their birthdate was out of testing range?
