I'm sure others will chime in, but in general terms, the CogAT doesn't provide IQ scores, but it is normed in the same way that IQ scores are (using standard deviations from the norm, along a curve), using standard age scores. But it's a group administered test that measures ability in a school setting rather than individually assessing cognitive ability. It has the potential to miss gifted kids (particularly if they think things through deeply). If you search the archives, you can find some more helpful advice. Since the K-2 test is given orally, if your child does better with viewing test questions, they may score higher when given the test in 3rd grade or above.
CogAT scores are given in 'stanines,' with strengths and weaknesses in learning profiles. You can then look up the profile score on their website and get information.
-Stanine 9 is top 4% (96th percentile and up) "Very high"
-Stanine 8 is the next 7% (89-95th percentile) "Above average"
-Stanine 7 is the next 12% (77-88th percentile) "Above average"
-Stanine 6 (60-76th percentile) is "Average"

Where your school draws the line for GT services may depend on a combination of CogAT, Iowa Assessment (ITBS) scores, and other information.
