I second blackcat's suggestion on contacting your state's DOE to clarify the procedural safeguards. Double check that there are 65 business days in the safeguards, because my district says a bunch of verbal stuff that are just whoppers.

My understanding is that districts can deny a request for evaluation, but they cannot ignore a request for evaluation. I would look at the wording on the signed consent form and make sure that the timeline was not altered. Just my 2 cents too.
