I hope you don't mind CLaw but I've read some of your posts but not replied as no advice to offer.
I would like to put forward a little ditty
it is to the tune of Gloria Gaynor's I will survive
"At first I was refrained, I was dignified
I tried oh so many times to get you on our side,
but then you spent so much time just trying to prove me wrong
I grew strong
I decided it was time to move on
Yes, that's right,
I've found a new school
Did you really think we'd stick around trying to play by your rule?
You can stick your IEP, you can stick your happy card sign
you can stick them right where the sun doesn't shine
I will survive
I will survive
As I know how to make sure my son will thrive
I tried for far too long
to make it it all work
but I was wrong, cos you are a massive jerk
As for
the teacher of the class
she wouldn't know ASD if it bit her on the arse
your SENCo is insane
but as Head you are the most to blame
It's plain to see
and not just to me
Parent Partnership
are onto you
oh and Autism Outreach too
It won't be long until the EP follows suit
I expect your arse will meet with the boot
I can't say I will cry
or call around to say bye
I will survive
I will survive
As I know how to make sure my son will thrive
I tried for far too long
to make it it all work
but I was wrong, cos you are a massive jerk"
