This report is about all the Nordic countries and I am supposed to deliver a summary of a publication about a Swedish way of working with validation, that is both actual and of interest for the colleagues in Europe. Instead of doing a summary I have chosen two short chapters in the report that deal with the use of concepts in the field of validation. In many countries there is an ongoing discussion about different concepts used in the context of validation. Chapter two is about definitions of validation, while chapter three is about perspectives on validation. These two chapters are presented below with exact wording as in the report.
