According to article 86 of Law 4957/2022, registered students of a Postgraduate Studies Program (P.M.S.) may study for free, if tuition fees are required, provided that they meet the legal financial or social criteria. A prerequisite for granting the right to study for free due to financial or social criteria is the fulfillment of the requirements for excellence during the first cycle of studies, which corresponds at least to the possession of a grade equal to or higher than seven and a half with an excellent grade out of ten (7.5/10), provided that the evaluation in the basic qualification submitted for admission to the P.M.S. has been carried out according to the ten-point evaluation scale of a domestic Higher Educational Institution (HEI), otherwise this criterion is applied proportionally according to the respective evaluation scale, provided that the submitted academic title has been granted by a foreign Institution.

 The total number of students who study free of charge may not exceed the number corresponding to thirty percent (30%) of the total number of registered students per academic year. If, during the numerical calculation of the number of beneficiaries of exemption from tuition fees, a decimal number results, it is rounded to the nearest whole unit. If the number of beneficiaries of exemption exceeds the percentage herein, the beneficiaries are selected in descending order of ranking until the number is completed.

 The submission of applications for free tuition per P.M.S. takes place after the completion of the student admission process to the P.M.S. and within a period of time to be determined by the P.M.S. itself.
