For regulated professions (healthcare including doctors, nurses, pharmacists, dentists; legal services; teaching; specific engineering disciplines), formal recognition through relevant Belgian authorities is required. Recognition procedures differ by region and community with NARIC-Vlaanderen for Flemish Community, Service francophone des équivalences for French Community, and Deutschsprachige Gemeinschaft for German-speaking Community.
