Yes, as deacongirl says, you can find a lot of discussion re: Cogat here. I find that a google search of cogat and this site will get you better results than the search box here.
If you have money to spare, an IQ test with a psychologist who is familiar with GT kids can be very useful. We received a long and detailed report explaining what all the scores meant. This was helpful in getting a needed grade skip for our son, and also very useful just to understand what type of schooling might work best for our kiddo. (Think flexible.) It's nice to get a better idea of where exactly your child falls. It helps you to figure out if the MAP scores are right on or possibly lower than they could be due to things just not being taught, or even possibly a hidden disability.
