The National Service Framework for Mental Health (NSF–MH) is a strategic blueprint for services for adults of working age for the next 10 years. It is both mandatory, in being a clear statement of what services must seek to achieve in relation to the given standards and performance indicators, and permissive, in that it allows considerable local flexibility to customise the services which need to be provided to fit the framework. This paper summarises the process by which the NSF was created, and its content, which became clear when it was published on 30 September 1999 (Department of Health, 1999).
