I think the test varies on the age of the child and also from school district to school district. My daughter was tested in the 3rd grade and then we moved before the result of the test arrived...the new school district didn't recognize the results of that test. I finally was able to have her tested(after much talking and her desire to be in the program) when she was in the 6th grade. She loved her class and learned so much. She is an awesome writer and communicator. Hang in there with the test for your son and if he doesn't do well you can always have him tested again. I think it is especially important if this is something that he is wanting. Good luck...let us know the outcome of the test.
