I think you should ignore all the nonsense tbh. The cost of the placement will be the same. SALTs do not charge less/more because of the funding changes do they?
Star, my problem is that the LA is lying to Tribunal about the cost of putting my son into ANY primary school. So I have to know what the cost of ANY placement is WITHOUT the bolt-ons (they and I agree on the hourly rates of these bolt-ons).
Getting the correct figure is absolutely crucial because it is a matter of a few thousands between the actual cost of the LA compared to my indie school WITHOUT us having to argue over the contested provision.
So I'm not concerned about bolt-ons or where the money is coming from. I want to know is AWPU the accepted 'unit of measure' (for want of a better term) to decide how much is the hard-cash cost of any child.
Because, you see in the ridiculousness of my trip to Tribunal, if Essex County Council use their own AWPU and not the made up figure they've dreamt up from nowhere, their school is more than mine. If they use the AWPU, then their argument that the indie school is not in the interest of the public money is total and utter nonsense and my trip to Tribunal next week is all about institutional bullying.
Step away from the computer.... And breath....
