We won't have a 504 update meeting until fall. I will bring up an IEP again at that time, but as I've tried for the past 3 years, I won't hold my breath. I can also try to get a keyboard added to his accommodations, but I admit I'm hesitant. I think ds's writing has improved under his current accommodation and I'm hopeful it will continue to improve with teacher support, understanding and encouragement.
I would never consider our public school (huge and understaffed) for ds and we cannot afford private school. The charter school he attends is doing a fantastic job. They have quite a waiting list. Ds will mainly be with a core group, however, he will be pulled out for advanced English, math and science. This is a good thing as he will be with his friends, some of whom have diagnoses similar to ds.
Polarbear, your response was very helpful. Thank you.
