In particular, Directive 92/51, which had to be transposed in all the Member States before 18 June 1994, set up a general system of recognition of diplomas awarded on completion of professional education and training lasting three years or less following the equivalent of baccalauréat/A-levels (an equivalent mechanism was set up by Directive 89/48/EEC for general recognition of diplomas awarded on completion of professional education and training of more than three years' duration following the equivalent of baccalauréat/A-levels).
La directive 92/51, qui devait être transposée dans tous les Etats membres avant le 18 juin 1994, a mis en place un système général de reconnaissance des diplômes pour les professions de niveau inférieur à "baccalauréat plus trois ans" (pour les professions de niveau égal ou supérieur à "baccalauréat plus trois ans", la directive 89/48/CEE avait mis en place un dispositif équivalent).
