The Directorate for Integration and Diversity (IMDi) is the national expert authority for interpreting in the public sector. IMDi is responsible for the National Register of Interpreters and for licensing state-authorised interpreters. All administrative levels, sector authorities and municipalities have an independent responsibility to develop good routines for booking, using, paying for and quality assuring the services of interpreters.

IMDi has prepared a guide for the purchase of interpreting services. This guide is available from www.tolkeportalen.no.
