Something like this happened to me this year (although I do make every meeting). My DD had an IEP meeting and I was going to be there, but my husband's face swelled up the size of a softball from an abscess. The dentist's office wanted to see him right away, so I called the school to tell them WHY I wasn't attending the meeting -- spoke to the office secretary. Just as an offhand remark, I said, "I bet they're going to release her from the IEP... I hope not." She told me she wasn't sure, but that she'd forward me all the paperwork. I asked her to make sure to tell the teacher & sped director why I wasn't there, and she assured me she would.
Yeah, she sure gave them ONE version of why I wasn't there.
The next morning, my DD's teacher called me and was sounding really defensive towards me, asking me why I thought they'd release DD from her IEP, and I explained that it was just my experience with the sped dept, so she told me that they actually didn't. I told her I was glad. She continued to sound really defensive with me and I couldn't figure it out.

Towards the end of the conversation, she said something about me not being at the meeting and that it's a shame I didn't go because I mistakenly thought they'd be releasing her.
Huh?
It turned out, the secretary failed to mention the part about my DH being sick and that I actually said I wasn't coming because, why bother? They were releasing her from the IEP.

Nice, huh?
