My DS is only 5 and in K so I don't have much experience but I'll let you know what they do with him FWIW. He is pulled out once every two weeks for about 20mins. From what I've been able to discern they read a book, have the kids learn to ask questions and question everything, go over some math problems from books like The Grapes of Math, talk about paintings hanging in the teacher's room, etc. It seems to be a random hodge-podge of things that the kids might find interesting.
This group appears to have been put together after I talked to the teacher and principal about some of my concerns. I don't get the feeling that this school usually has the kindergarteners involved in GT so it is a bit of a learning curve for all involved.
I know nothing about IEPs so I can't comment there but it seems like your DS isn't happy. It does not sound worth your, or his, time. Can you talk to the GT teacher and ask her about this?
I hope this ends up working out for you. Good luck!
p.s. If you end up keeping him there i would make them give him a student ID or the ability to use a school account so he can participate fully. He is currently a student there whether enrolled full time or not.
