This comparative study presents two different higher education accreditation systems, which are carried out by the Yemeni Accreditation Council (YAC) and the German Accreditation Council (GAC) in the two countries, Yemen and Germany. After an examination of the Yemeni Accreditation Council and the German Accreditation Council's literature, their recently developmental accreditation systems and practical methods are subject to entirely detailed analysis. As a result, the findings of the two councils' literature analysis reveal that there is a large gap between the Yemeni and the German Higher Education Systems in the implementation of accreditation. Accordingly, it is strongly recommended that the Yemeni Accreditation Council should benefit from the positive elements of the German Accreditation Council for example, appointments of accreditation agencies, expert groups and the German accreditation system procedures, the accreditation of accreditation agencies, the internal review and the external review which may help the YAC to create the necessary mechanisms for the quality assessment improvement within the Yemeni higher education institutions.
