(12)This Directive concerns the recognition by Member States of professional qualifications acquired in other Member States. It does not, however, concern the recognition by Member States of recognition decisions adopted by other Member States pursuant to this Directive. Consequently, individuals holding professional qualifications which have been recognised pursuant to this Directive may not use such recognition to obtain in their Member State of origin rights different from those conferred by the professional qualification obtained in that Member State, unless they provide evidence that they have obtained additional professional qualifications in the host Member State.
