Eventuelle forskelle kan udlignes af en supplerende erhvervserfaringsperiode for så vidt angår studiernes varighed eller ved et praktikantophold i værtslandet for så vidt angår betingelserne for udøvelse af erhvervet.
Any disparities may be rectified either, as regards the length of studies, by an additional period of professional experience or, as regards the conditions for engaging in professional activities, by a training period in the host country.
