How to Interpret CogAT Results

While they may look a bit intimidating, interpreting your child’s CogAT results is actually quite simple. Begin by looking at each stanine score. A stanine is simply an unfamiliar word for a familiar thing: a normalized standard score scale. Stanines range between one and nine. You should see three stanine scores. For example, we’ll use a stanine score of nine. This corresponds to a score between the 96th and 99th percentiles, indicating that your child scored above 96 to 99 percent of his peers. A stanine score above five is considered above average.

CogAT results given in percentiles are much easier to interpret. If your child receives a score in the 97th percentile, this indicates that she is in the top three percent of test-takers, and that she scored above 97 percent of her peers.

You should see individual scores and percentiles for each section of the three sections of the CogAT, as well as a combined score. If you find anything confusing, simply as your child’s school to better explain the CogAT results.
