I've kind of whizzed over the thread but am surprised not to have spotted any mention of CAF yet.
It seems to me that whilst under resourced CSF is indeed one problem not easily solved, the other serious issue here is the failure of professionals to liaise.
It was exactly this problem that brought about the CAF following recommendations in Lord Laming's report.
However, despite the CAF, (though admittedly in its infancy) many bodies remain reluctant to partnership work. Typically Health, and Social Services are notoriously poor at information sharing as they perhpas used to a long tradition of working on a tight 'need to know' basis.
Organisations are improving with info sharing within their own organisations but still the sharing of concerns between agencies is slow to non existent.
Data Protection laws further muddy the waters and when you consider the significant level of confusion around how the CAF is to be implemented it is little wonder that we still do not have a truly effective systematic approach to disallowing children from slipping through the net.
I doubt that what we need is an overhaul or a rethink on how we are to lessen the numbers of children 'missed' by professionals. However, I do feel that more consideration needs to be given to how we implement systems in place and ensure that all staff are adequately trained and resourced for dealing with problems as they arise.
It is a great failing of an excellent systematic approach [the CAF] that, for example, midday supervisors and other school support staff do not receive CAF training.
