I did our due process without an attorney. I would NOT recommend it. Marte has stats, but bottom line is going to due process without an attorney is a fast way to lose. Even if you ARE well versed.
Our district played very dirty, hard ball, nasty. They twisted every law, brought papers - IEPs that were very old, mixed in between pages of newer IEPs, accused our doctor of not being a doctor at all (mostly just to force us to have to call our doctor in in person from quite far away- to defend HERSELF and to muddy the water, trying to take focus of themself)
Our hearing officer herself did not even honor and follow federal law re timelines etc.......
In my state, due process does not have a possibility to appeal a case, so if you lose, you have no recourse. The outcome in our case was not even clear. I ordered transcripts of our entire case, an te transcripts did NOT mach up to ANY of the testimony. In hindsight, I wish we had had repreentation, if only so that we would have had someone to back us up on the transcripts being falsified and to hold the hearing oficer to federal law.
