I received a response to my email almost immediately.
The school has agreed to modify the dates of the IEP to 8/20 - 10/20/2008. This is the scenario I wanted the most. I was concerned that if we met in July to draft goals for Erin, she would likely meet them before the school year started - or very soon thereafter.
Also, this will give the Teacher of the Deaf that has been assigned to Erin the chance to see Erin's school and get a better feel for what she may or may not need there in the way of services.
My only remaining concern is the frequent advice I have received that it is harder to get new services added to subsequent IEPs after signing the initial. But it is a gamble I am willing to take at this point.
I think this is the best scenario for all parties - and most importantly, the best scenario for Erin.
What a relief to have this resolved - at least for now.
