Last year was a rough one for my son, and we started with the teachers but explaining what wasn't working, why it wasn't working, and what we thought would resolve the problem. For some, that was all that was needed. For a couple, it was like we'd thrown down the gauntlet. The only remedy was going to the Special Ed Chair and asking for a meeting. She was very supportive and wrote out an IEP addendum on the spot. We signed, she signed, she had the principal sign, and it was part of the IEP.
Hope this helps.
