While this seems like the obvious choice to go up the chain- I have experienced sometimes it leads to the ultimate dead end- as sometimes that is where the directive is coming from. The benefit of going up the chain however is you will know definitively if you are wasting your time with this school. If the directive is coming from the top- you will have no alternative but to find other placement for your child. Which others on the thread ah e pointed out- may be the best solution anyway. Good luck.
