2E seems to be a really hard concept for the teachers to grasp. I was sitting in our IEP/PT conference recently and was suddenly struck by how grateful I was that the Emotional Support Teacher, Special Needs Coordinator and Gifted teacher were in the room for the conference with the main teacher. If it had just been me and the teacher, I think I would have been very frustrated. I really don't think that they main teachers pay much attention to IEPs. The comments and concerns that were raised were addressed by the "experts" right then and there. When I made a comment one of them usually chimed in with suggestions for me or the teacher that we could all discuss and make sure could be implemented before we left the room.
In fact, for the first time ever, I was the one saying hey we need to watch out here, this is still just a 9 year old boy and I think he is close to the overload point.
Good Luck!
