KLEIS-Workshop for Greek Language and Culture is since January 2017 recognised by the Centre of Greek Language (CGL) as the examination centre for the Certificate of Attainment in Greek in Chania .
The Certificate of Attainment in Greek was established in November 1998 by the Greek Ministry of Education. It responds to a persisting request of all learners of Greek in Greece and abroad for a state certificate of attainment available at various levels. The Centre of Greek Language (CGL) has been assigned the exclusive and overall responsibility for the examination procedure through which the certificate of attainment in Greek may be awarded and has been conducting the examinations since 1999.
