New government proposals for interagency cooperation are geared to creating a system of integrated working relationships through 'joint training, involving staff from all relevant agencies, as an effective way of promoting shared understanding' (Working Together, Department of Health 1998). One of the chief targets stated is 'the promotion of healthy schools as the area of greatest potential to tackle the inequalities set in childhood'. However, the Joseph Rowntree Foundation reminds us, on the one hand, how new such a jointly facilitating approach is to teachers and school management, and that this 'requires additional elements in teacher training', and on the other hand, that 'agencies may not welcome collaboration, especially where they have lost territory to education' (Ball 1998). Lacey and Lomas (1993) refer to the need of developing, for teachers, 'a whole set of new skills, knowledge and understanding', including an understanding of reasons for wanting to resist proposed changes.
