An interactive toolkit, developed to support the implementation of the Social Services and Wellbeing (Wales) Act, which provides information and advice to support Local Authorities and Health Boards to undertake an assessment of care and support needs and carers' needs in their local area. The toolkit is in three main sections. Section one (the ‘What’ guide) looks at what is required under the Social Services and Wellbeing (Wales) Act, the benefits of carrying out an assessment, analysing the data, and what should be included in the report.
