“41. … the whole tenor of the Framework document and of the other guidance … is that the outcome of the child protection path for a child in need should be something equivalent to a core assessment; and if that has not been achieved by the time of deregistration, it should be achieved at that point if the child remains a child in need. There should be a systematic assessment of needs which takes into account the three domains (child’s developmental needs, parenting capacity, family and environmental factors) and involves collaboration between all relevant agencies so as to achieve a full understanding of the child in his or her family and community context. It is important, moreover, to be clear about the three-stage process: identification of needs, production of a care plan, and provision of the identified services. It seems to me that where an authority follows a path that does not involve the preparation of a core assessment as such, it must nevertheless adopt a similarly systematic approach with a view to achievement of the same objectives. Failure to do so without good cause will constitute an impermissible departure from the guidance.”
