Directive 2005/36/EC of the European Parliament and of the CouncilShow full title

Article 12 Equal treatment of qualifications

Any evidence of formal qualifications or set of evidence of formal qualifications issued by a competent authority in a Member State, certifying successful completion of training in the Community which is recognised by that Member State as being of an equivalent level and which confers on the holder the same rights of access to or pursuit of a profession or prepares for the pursuit of that profession, shall be treated as evidence of formal qualifications of the type covered by Article 11, including the level in question.

Any professional qualification which, although not satisfying the requirements contained in the legislative, regulatory or administrative provisions in force in the home Member State for access to or the pursuit of a profession, confers on the holder acquired rights by virtue of these provisions, shall also be treated as such evidence of formal qualifications under the same conditions as set out in the first subparagraph. This applies in particular if the home Member State raises the level of training required for admission to a profession and for its exercise, and if an individual who has undergone former training, which does not meet the requirements of the new qualification, benefits from acquired rights by virtue of national legislative, regulatory or administrative provisions; in such case this former training is considered by the host Member State, for the purposes of the application of Article 13, as corresponding to the level of the new training.
