How do PT, OT, SLP....know what to work on? What are the goals? Are there goals? And if there are goals....sounds like an IEP to me.
I suppose there's nothing in IDEA preventing a student from having a 504 with FOUR related services....but it's odd. Why not just give an IEP when it's obvious the child needs it? To prevent having to progress monitor, maybe? Who knows why they do what they do.
Read up on IEEs if you haven't already. You may want to consider asking for one if you disagree with their evaluations. Ditto to what Carolyn said about keeping track of the school refusal stuff.
Remember tomorrow you don't have to agree to anything, you can just listen and process the information over the weekend. (and post it here, of course)
