Accreditation has become an important issue in Spain. This paper presents an overview of Spain's accreditation system; a system which is relatively new and has evolved rapidly, fostered by legislative mandates which established accreditation bodies to regulate the quality of higher education institutions. One of the initial challenges faced by accrediting agencies and universities in Spain was the need for a national curricular reform to transform the degree offerings across the country to match with the new European degree system. Discussion about the emergence of the accreditation system and the experiences of accreditors and academics during the nationwide curricular reform are included.
