My understanding is that any student (ND or gifted) could take the SAT as a middle schooler if he/she wanted. You don't have to take it as part of a talent search. Some talent searches only want 7th graders testing, so if I want my kid to take it in 8th grade, I have to register on my own. There is no reason an ND kid couldn't do the same. I know plenty of GT kids who opted out of taking it as 7th graders, but for my money, it's a great chance to take the test before it counts. I don't see why that's unfair - it's open to ND and GT alike.
