I know the problem a lot of parents faced was that their kids were getting punted into a hub that wasn't at their child's own school. For example, one of my workmate's has an 8 year old daughter. Her local hub was in a secondary school, nobody else from her class would have been there, and none of the staff from her school. If they had kept all the kids going to their own schools then I'm sure the uptake would have been higher.
