As for CTY my child has had a standardized test and my understanding is that because of that I cannot self nominate.
CTY requires a SCAT test at a local testing center and costs less than $100 and is taken on a computer. Is that what you are mentioning or is it something else? (DYS, on the other hand requires IQ test results or an Explore-test/Portfolio option).
ETA: If your child had an ITBS like test that you self administered, then it should be OK to send in the scores to CTY for qualification to take SCAT. The test results are from the test provider, so it does not matter who the nominator is.
