'2) can a statement be used to legally enforce e.g. 15hours of 1 to 1 support? he has never seen a statement written in this way but did not rule out some could be. in a typical statement, the school has a legal obligation to meet the child's needs, as defined in the statement but the legally enforce part does not detail how those needs should be met.'
If the statement does not detail how those needs should be met it is either a) a bad statement or b) a statement written with the purpose of the resources allocated to be used flexibly at the discretion of the teacher and school as the needs of the child have been assessed as requiring this kind of support.
However, if a child has 15 hours of 1:1 specified, then this is what the experts have deemed VITAL (as most of you know the LA isn't giving away money that isn't anything but essential and then more than likely a bit less) in order for that child to have their needs met adequately. Not well, not to fulfil their potential, - ADEQUATELY.
These hours are then protected in law (as would be flexible use of funding if that is what is specified) and as such CAN'T be removed or reallocated, no matter how greedy or selfish you think the parents of that child might be.
