DS, who has AS, is in Yr10 and I'd due to do work experience this year.
We had made one local enquiry, who had 'lots' of places but he received a letter saying they were full after we sent them the paperwork, including his health form which stated that he had AS.
DS then came home all excited about a residential summer school affiliated with NASA which was running the same week and would count as work experience!
It looked amazing but cost £500, I couldn't normally have afforded it but came into some money from an inheritance, I knew my DM would have approved so said yes.
We sent in an expression of interest, then several weeks later were invited to an information evening. DS and DH came home buzzing with excitement and we filled in paperwork confirming our consent and willingness to pay.
We've just had a call from the SENCO saying that the science teachers do not think it's appropriate for DS due to the lack of adult support (it's run by an outside company).
Why couldn't they have told us this earlier? I've just had the worst conversation ever having to explain to DS that he won't be going. 
He's been very Aspie recently and has has had some behaviour and anger issues so I can see their point. It's still hard though.
