JRB -
How frustrating.
I'm quite sure that you need a 504 plan, and I would request one, in writing, on paper, to the Principle or the Special Education Department.
Even though I like all the consiliatory things everyone is saying, I would consider, in this situation, writing a letter, on paper, quoting all the emails you've sent that have gone unanswered, sort of a -
'I understand that emails can get lost, so I am sending you and the Principle this letter outlining all of the attempts that I have made to contact you. My son is very unhappy and failing Math, and waiting 2 weeks for an appointment to sit down with you seems unreasonable. I understand that you are very busy, but perhaps we could find a sooner time to sit down together and discuss this situation before this situation gets any more out of hand.'
I would hand deliver it to the principle and put it into the teacher's in box. Then duck and cover (as I will now do!)
Anxiety is a serious medical condition. Your son is 11 years old! It's high time that the school respond to your concerns.
BTW - what grade is this? Is this the first year in Middle School or the last year in Elementary?
Love and More Love,
