I apologize for getting so granular on the topic, but who's to say they won't just throw out the printed version? It doesn't require a signature, so they can say they didn't need to keep it. For what it's worth - it's the district special education contact now stepping in and saying they don't include parental feedback. Previously the school accepted it and included it.
I've heard of people writing it in the IEP under parental concerns. I'm not sure this is appropriate, but I don't know where else it could be documented, and they haven't replied to my email asking this.
Thank you!
