State schools are generally seen as equivalent in quality of education to private-sector institutions. However, the value of a state high-school diploma is limited by the fact that the grades obtained account for only around 25% of the final grade for each topic, with the remaining 75% assigned by the teacher during the semester, in a minimally transparent way. Cypriot universities (like universities in Greece) ignore high school grades almost entirely for admissions purposes. While a high-school diploma is mandatory for university attendance, admissions are decided almost exclusively on the basis of scores at centrally administered university entrance examinations that all university candidates are required to take.
