I have left a note with teacher about asking for extra time at parents'evening to discuss DS's additional educational needs.
I also 'reminded' school that i would like to be told of when SALT goes in to see DS at school so i can have a chat with her afterwards.
So far so good, they have agreed to the above requests.
But i also wanted to speak to SALT (before she actually goes in mid-november) about my growing concerns that strategies are not being used because DS appears to be coping and school isn't giving me any feedback at all about his difficulties and what they are doing to met his needs.
And this where i did wrong. 
I just was way too emotional on the phone, just couldn't help it.
All the worry and stress over the school issue for the past month, just came out and i was so close to bubbling on the phone. 
SALT who has worked with DS twice a week during his year at the lang.unit knows him very well, and did agree from what i said that 'there seem to be some discrepencies between what DS is able to do and what teacher is writting on his communication book'.
I know she could hear and sense i was highly upset and she was trying to find explanations such as 'because of the autism DX, maybe teacher was expecting a child with a very different presentation, and of course DS is so passive so she thinks he is doing well'... i can see her point.
Anyway to get to the point, she said she will phone up the LSA who is supposed to be doing 1:1 with DS and will ask a few questions about strategies, IEP, get to the bottom of what support DS is getting.
She said she will go in to see teacher and see what teacher's understanding and opinion about DS's difficulties and needs are.
And she will get back to me before half-term with some info.
SALT was always lovely and one of the few professionals who actually did understand DS.
But i feel such an idiot with my emotional outburst to her.
