I just received my DS7's CogAT report from the school today. This is one of three scores that the school uses to qualify students into the advanced programs.

I have a couple of questions on the test result.

The CogAT Explanation for Parents that longcut provided shows a standard age score, but our report only shows the age stanine and age % rank. The report also provides the raw scores. Is there anyway to calculate the standard age score? Is it equivalent to the IQ score?

DS7 got the highest possible scaled score (19) on both visual spatial subtests on the WISC V test. It is actually his strongest area and we can see it from his love of art and visual puzzles. However, his CogAT nonverbal score only puts him at 91%. I was quite surprised to see that score. Is this normal?

Although all three test scores still put him in the 99%, I am curious to know how the CogAT result in nonverbal could be so different from the WISC.

Thank you
