My son recently took the Cogat for GT placement. He scored the following:

Age Percentile Rank

Verbal 99%
Quantitative 99%
Non Verbal 99%
Composite 99%

Based on these numbers I know he did well. However, I can't tell how significant these scores are other than he should be in the top 1%.

Our district requires passage of both cogat and ITBS at 97%. My son missed his ITBS requirements by one point. I'm debating filing an appeal (or taking him for a private test). However, prior to doing that; I want to make sure I have a base understanding on what these scores mean. Any help you can lend is appreciate it.

To make matters more complicated, in first grade he had the reverse situation with his scores... Achievement=99.9% and IQ =95%. Is this kid "gifted" or is this just a fluke?

Thank you for your help!
