A standard age score is one of several different labels that have been given to what is called a standard score. It is comparable to an IQ score. I’m not real familiar with the Cognitive Abilities Test but I am very familiar with other tests of cognitive abilities such as the Stanford Binet Intelligence Scale which also reports what is termed a Standard Age Score. On tests that use standard scores as a way of reporting a child’s performance a score of 100 is considered an “average” score. I would want to know what the standard deviation of this particular test is to most precisely define the average range. Most tests like this have a standard deviation of 15 score points. That means that a standard age score that falls between 85 (15 points beleow 100) and 115 (15 points above 100) would be within the “average” range. A score below 85 would be “below average” and score above 115 would be considered “above average.” A score of 130 (30 points above 100) would be considered “well above average” and is within a range that is often recognized as “gifted.”

Some tests have a standard deviation of 16. In that case scores between 84 and 116 are considered within the “average” range.

If you go to the “LD in Depth” section of this website and click on “assessments”, there is a very good article that explains test scores and what they mean. It explains all the different ways scores are reported and how to interpret test results.

A range of 85-115 is considered average. 85 being low average and 115 being high average.
