The Norwegian agency for quality assurance in education (NOKUT) grants general recognition of foreign higher education. As a rule any accreditation obtained in an EU/EEA country will be recognised in Norway with no additional assessment required.
Some professions require authorisation before you can practice, such as in the health sector where you apply through the Norwegian Registration Authority for Health Personnel (SAK). See below.
You will also find a list of regulated professions and authorising institutions at the NOKUT website, as well as information about educational systems in other countries and the laws and regulations that govern recognition of foreign education.
