One thing to note. I have had teachers who admitted to me that they didn't realize my DD had an IEP until a month into the new school year. And this was a veteran teacher. So after that I always gave a heads up to that teacher that DD had an IEP.

Note that was the year the support specialist was brand new and blew me off when I mentioned something to her in the first few days. And who another parent found giving help for the wrong subject about 2 months in. She just had time in her schedule during math for that class, so she helped the two kids who had IEP's with math. When both had language based IEP's.

I had many problems that year. Her excuse was that DD didn't seem like she had an IEP since she was so cheerful & happy. She had some preconceived idea that kids will challenges must all be miserable in school by 5th grade. Yes my kid was quiet & otherwise cheerful didn't mean that she was doing OK. SIGH.. She's still that way totally charmed the person I hired to help her job search who has NO clue what she's capable of doing.
