My special needs son has been in two different school systems, and one has clearly gotten good results, while the other has clearly gotten bad results. I have split decision making with my ex, and the ex will not budge on their school of choice, which also happens to be where the children are currently attending. This case has already been ordered to an arbitrator, but it's been over a year, I've sent the arbitrator two evidence packets now, and still no hint that we're even getting closer to a decision. I am very uncomfortable with this, as in waiting for a decision to be made, my son is going to a school that I feel is actually making him worse. I do not want to go through another year of him in a school that can not meet his needs. Who to write? What to say?
