It really is.
I was just lamenting about this to my boyfriend last week. Had a parent not show up for an IEP meeting. The meeting had already been rescheduled once. This is for a very high needs preschool student so there were a lot of people there for the meeting- psych, OT, PT, ST, nurse, and the teacher that we had slated for this student when they start (child is not quite 3). We had two hours blocked out on the calendar for this and they don't show. No call and didn't answer when we called.
When I was talking about it to my boyfriend, he was like "Oh, I guess they're out of luck then!" but NOPE. We will just continue to accommodate to them because that's what we have to do.
