We will probably get an IQ test for our 7yo son this summer, administered privately (few MA schools have gifted programs). An IQ test takes a few hours, right? We will have to travel some distance to have him tested. After all that, he will certainly be very curious about his score afterward (I understand that scoring the test and writing up the results may take weeks), and I think he has a right to know what it is.
Furthermore, part of the reason to have him tested is have him join Davidson Young Scholars. If he qualifies, he will be able to look up on the web that his score exceeds 145. What is the point of suppressing the actual score?
