Quality is a main issue when practices of validation are developed. In the Nordic countries, a model of quality assurance in validation has been introduced, to be applied in the development of validation practices. The model puts the individual at the centre and introduces eight factors for quality: information, preconditions, documentation, coordination, guidance, mapping, assessment, and follow-up. This article presents and discusses the Nordic model as a tool for quality work in validation. In the discussion on the model, some more general concepts and perspectives on quality in validation are introduced, such as the call for a balance between flexibility and standardisation, and the need to understand quality in relation to the possible aims of the validation process. The article also applies the model to the analysis of a project for the development of validation work in cooperation between the municipalities in the region of East Sweden, in which the model appears to be useful for understanding and developing validation work.
