The CogAT is scored based on a student’s raw score, which is the total number of correct answers they provide on the test. 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. A percentile rank of 80 means that child’s score was higher than 80% of students who took the same test. School districts use this number to compare students that share the same age and grade level.

The Standard Age Score has a maximum possible score of 160 the average score is 100. This allows an evaluator to understand a student’s individual strengths and weaknesses across different types of cognitive abilities. The USS are calculated separately for each of the test’s three batteries: verbal, nonverbal, and quantitative reasoning skills. The conversion involves statistical procedures that ensure the scores are not influenced by variations in difficulty across different forms of the test. After a student’s raw score (the total number of questions answered correctly) is determined, it is converted to the USS. The USS is a type of normalized standard score that follows a consistent scale from kindergarten through 12th grade for the CogAT. The Composite USS is determined by averaging these three different scores. There are separate USS scores for each of the test’s three verbal, nonverbal and quantitative reasoning skills subsections (also called “batteries”). After the Raw Score is determined, it is converted to a normalized standard score known as the Universal Scale Score. This is total number of questions answered correctly however, incorrect answers do not cause points to be deducted from the overall raw score.
