I went back and looked at your previous posts about all kinds of things from behavioral and learning issues (PDD-NOS, autism, IEPs, math etc.) and I have to say I'm really confused about why you are now working so hard on placement in Honors classes for kids you are not sure are gifted or not. (Not sure what "AR" is - do you mean "AP"?).
I'm also concerned about the use of the word "try" - you want them to "try" for this new designation of Gifted/Talented, as if it's an admissions test or an SAT type of exam? There's so much stress around tests required for various admissions functions, when what you should be looking at is "evaluation" or "assessment". This is nothing that kids "TRY" for. And if your district is using the term "qualified" for a cluster, that's a problem.
I'm really rather bewildered by all the labeling and the insistence on more-more-more for kids. FYI my child has no labels, and he didn't test out of or into any programs. He never took AP classes until senior year when he took an AP computer science class - but it had no bearing on his college applications/acceptances. He got into a great school and did well. But as more and more colleges move AWAY from standardized testing as poor indicators of future success (or at least as they make an option of SAT vs. ACT), it seems counterproductive to go back to more and more testing of young kids to segregate them (call it clustering if you want, it's still separating them and labeling them).
I am far more concerned about the constant pressure on kids to be in "this" group or "that" group, and about the effect on kids who are not designated as G/T. I'm not sure it's a big indicator of future success. While no one wants a child to be left behind or segregated when he/she could have been mainstreamed, and no one wants a child to sit in a class where he/she is not challenged, putting pressure on a child to "try" to do well on an exam which is just an assessment of where they are at is as futile as asking a child to "try" to achieve a certain level on a height chart or eye exam.
I think it's much more important for you to work with teachers for assessments on your triplets in every area and to make sure they are appropriately engaged on a daily basis. You're already working on the IEP level, your last post had to do with math, and now you're pushing them on the G/T level. I honestly don't know if this is a good move at all.
ETA: after your response in your SWH, I think what I was picking up what what you said about parents bragging! I think that's one of the saddest things about many school systems - kids being pushed at age 5 to get into Harvard! The stress on kids is so strong, and it actually interferes with their learnings, because they hare pushed to learn in order to meet some outside standard instead of them being taught to their natural abilities. Creativity is stifled so they can prove something. It's hard not to get sucked into that. The other problem is that kids in the "gifted" section are told by their parents that they are special and superior, and that info permeates their social interactions. The same issue, raised by one responder, about how will one of your children feel if the siblings are in the GATE program applies even more to other kids in the class. If parents would keep their mouths shut, it would be one thing - but you're saying it's already a problem that they don't.
I'm suggesting that you look at the many problems that occur with helicopter parenting and kids getting into college who are unable to engage in critical thinking or accept any sort of mistakes or "failure". It's a massive problem for college professors and residence hall adjustment counselors. SO Consider what you are wishing for.
