I have a feeling that even if you were able to get an IEP they wouldn't give him the help that he needs. They need to be able to see a problem. Maybe it would be better to invest in outside help/tutoring? Keep pursuing the 504 so that he can get accommodations, at least. If you haven't talked to the special ed director, I would suggest it, just to make a point if nothing else. You could also file a complaint with the State but if you haven't requested an eval, they probably wouldn't do anything or take you seriously. BTW, it's the same way here for a 504...the teacher is asked for their views, but they should also be asking for your input as well and considering the outside report. I brought in an outside psych report and they almost took it TOO seriously and wanted to copy the suggested recommendations practically word-for-word even though they weren't necessarily all approriate for DD.
