A three-year project placed home-school support workers in secondary schools. The intention was that they should work closely at operational level with other agencies to provide a cohesive local authority response to the needs of disaffected and excluded youngsters. Crucial distinctions emerged between project constraints, possibilities and bene®ts for agency personnel in the school-focused agencies and those external to the school. In relation to the external agencies, support workers ful®lled predominantly an information gathering and sharing role whereby they joined up the solutions of disparate agencies, whereas very effective forms of cooperation developed with the school-focused agencies.

More recently through legislation (for example, the 1989 Children Act and the 1996 Education Act) and guidance (for example, Department for Education and Employment), 1999; Department of Health, Home Of®ce and Department for Education and Employment, 1999; and Department of Health, 2000) the government has endorsed the importance of such cooperation by setting out speci®c requirements as to how agencies should work together in order to plan and implement`joined-up solutions' to social problems. However, inter-agency cooperation is recognised as problematic with clashes between professional cultures, competition between departments for local government funding, reductions in overall budgets and low morale being commonly cited as the main contributory factors (see, for example, Dyson and others, 1998;Hallett and Birchall, 1992;Vernon and Sinclair, 1998). Conducting an evaluation of a three-year Home Of®ce funded project Meeting Need and Challenging Crime in Partnership with Schools provided the opportunity to study the rhetoric and practice of inter-agency cooperation and to investigate the factors constraining and facilitating the implementation of joined-up solutions.

Thus it targeted assistance to those youngsters whose challenging behaviour and disaffection from school research has shown are indicators of the possibility of future offending (see for example, Audit Commission, 1996;Cullingford, 1999;Graham and Bowling, 1995).The project had two main aims which were to reduce the number of exclusions from school of youngsters with challenging behaviours and, in acknowledgement of the range of expertise required effectively to address their needs (Lupton and Sheppard, 1999) to ensure a cohesive loca...
