As title says: we have come to an agreement with our LA, so have withdrawn our appeal.
From a rubbish, vague, unspecified statement that steadfastly refused to even mention ABA let alone provide anything like it, we now have up to 12 months of ABA-lite.
We have 25 hours a week of LSA support, and the LA will pay for the LSA to have training in ABA - and/or will employ our tutors as LSAs. Targets to be agreed jointly with our supervisor. 5 days training a year, plus 5 group sessions a year for all tutors/LSAs.
SALT up from 3 hours a year to weekly sessions.
It became clear a couple of months ago that ds is making such good progess (cos of ABA, obviously) that he doesn't need an intensive programme or a 1:1 shadow any more, so this is better than we could have wished for.
And great for the school - they get a brilliantly trained extra pair of hands milling around, helping out, and initiating great games for the kids.
Now just have to kick the school's arse into shape about providing what is in the statement - gloves are off now.
Thank you to everyone who has given me such fantastic help & advice - especially starlight, agnes, AT, wetaugust, and silverfrog and probably loads of others I've forgotten 
. And agnes in particular thanks for the recommendation of FS - she was amazing.
Hmm. Ds at school, dd at nursery today. Feels very strange that for the first time in 2 years I have a day to myself where I'm not scouring the net for info, writing reports, ploughing through emails, speaking to advocate/EP/SALT/ABA consultant/school, chasing up other people, organising files etc. Don't know what to do with myself.
Actually that's not true - I know exactly what I'm going to do, which is go shopping and spend DP's money which would otherwise have gone on tribunal & ABA costs
