The fact that your diploma is obtained in Europe or that it is covered by the Bologna Process does not necessarily mean that it is automatically recognised in Belgium.
You may be asked to apply for equivalence in connection with recruitment in certain sectors (public administrations in particular) or for access to certain types of studies (such as aggregation, training that prepares students for regulated teaching professions).
If your diploma was obtained outside the European Economic Area, or if you do not have the nationality of one of those countries, equivalence to a specific academic degree is essential for practising regulated professions.
For more information, see "What is equivalence?".
The only exception to these principles concerns the equivalence of study levels for diplomas awarded within the Benelux region. By reason of the decision taken on 18 May 2015 by the Benelux Committee of Ministers on the generic automatic mutual recognition of the level of higher education diplomas, adopted on 25 January 2018, holders of Dutch or Luxembourg diplomas at levels 5, 6, 7 and 8 of the European Qualification Framework do not have to take any steps with the Ministry of the Wallonia-Brussels Federation with a view to having their level recognised.
