Definition: The Lisbon Recognition Convention aims to facilitate the recognition of foreign degrees and diplomas among signatory states of Europe and North America. It set out basic principles of assessment and recognition and obliges each ratifying Party to ensure provisions for specific kinds of assessment exist. The principles include providing adequate and clear information on education systems such that competent recognition bodies can make well-founded judgments about the qualifications they issue, using transparent, coherent, and reliable procedures and criteria in assessment, giving mutual recognition of qualifications unless substantial differences in requirements can be shown, and justifying refusals of recognition.
