I hope this doesn't sound like trumpet blowing as DS used to attend TreeHouse, but I just got a copy of their latest Policy & Campaigns newsletter and it is very good. Lots of info about campaigns, e.g Blue Badge for ASD being raised in the House of Lords, input to Govt Review of Speech Lang & Communcation services and other things. It pulls together info about many different campaigns and issues into one newsletter. It is quite TH-orientated but then TH is not just a school but a nationwide charity promoting autism education and getting involved in many other ASD-related issues.
If you want a copy you can email [email protected] and also sign up to an Enewsletter at their website www.treehouse.org.uk
