The general system provides for an assessment, on a case-by-case basis, of the qualifications of an applicant against those required to practise in the host member state. If the activities covered by the profession in the home and the host member state are not comparable, then the qualifications cannot be recognised. If the activities are comparable but deficits in the qualifications are identified, subsequent post-qualification professional experience of the applicant must be considered. If deficits still remain, the host country must offer an applicant a compensation measure, i.e. a choice of completing an adaptation period or taking an aptitude test.
