What I don't understand is why school districts insist on using the CogAT as the sole determiner of GT status when it is not a protected test in that I, as a homeschooler, can order the CogAt to administer to my children. The exact same form of the test even!
Also, our district tests for GT placement in the spring and if a kid needs to be retested for some reason, they do that the next fall, so like 4 months later, using the same form of the CogAT one level up. At least half of the questions are the same as what were on the previous level.
