I need to send difficult child's school a letter requesting that we reevaluate his IEP because I feel its incomplete. A sample letter I found online gives a timeline of 5 business days for the school to respond to this request. The advocate I spoke with on Wednesday said to give them 10 days to respond. I called the school this morning to speak with the principal about a matter that needs to be addressed in R's IEP but that needs attention NOW. She wasn't in and according to the secretary will not be in until next Wednesday. If I were to send the letter today does her time to respond begin today or next Wednesday? I've tried looking around online but haven't found anything very specific.
