• The educational work of each academic year is structured in two study semesters, the winter and spring semesters, each of which includes at least thirteen (13) weeks of teaching and two (2) weeks of examinations. Repeat examinations for courses offered in the winter and spring semester are given in September.
• It is foreseen that, whenever a lecture is cancelled for any reason, this lecture should be given on a new date; in such cases, details (new date and time) must be posted on the IPGS website.
• Attendance of courses/seminars etc. is mandatory. A student is considered to have attended a course (and hence has the right to participate in the corresponding examination) only if he has attended at least 75% of the lectures corresponding to this course. Otherwise, the graduate student is obliged to repeat this course during the next academic year. If the percentage of a student’s absences exceeds 25% for all courses, the student may be considered for deletion from the student registry. If such an issue arises, it is discussed by the SC, which submits its recommendation to the CPS.
• The evaluation of students and their performance in the courses they are required to attend within the framework of the IPGS takes place at the end of each semester with written or oral examinations or is based on intermediate written assignments or a combination of all of the above. The evaluation method is determined by the instructor of each course. When conducting written or oral examinations, as evaluation methods, the integrity of the process must be guaranteed. Grading is done on a scale of 1-10. Examination results are announced by the instructor and are submitted to the Secretariat of the IPGS and the Department within four (4) weeks at the latest after the examination date. In the event that the above limit is repeatedly exceeded by an instructor, the Director must inform the CPS of the IPGS.
• The contribution (percentage) of the homework assignments into the final grade of each course is determined for each course separately, after a recommendation by the corresponding instructor and is mentioned explicitly in the Study Guide of the IPGS.
• Alternative assessment methods may be applied to deal with emergency needs or circumstances resulting from force majeure, such as conducting written or oral examinations by electronic means, provided that the integrity of the alternative process of assessment is guaranteed.
• It is possible to use alternative assessment methods for the performance of students with disabilities or special educational needs, after a decision of the SC and recommendation of the Committee for Disabled, taking into account relevant instructions of the Disabled Students Accessibility Unit of NKUA.
• The evaluation of students of second level programs of study that are organized by methods of distance learning may be conducted through distance examinations, provided that the integrity of the process is guaranteed.
• In the event of illness or recovery from a serious illness, instructors are advised to facilitate, in any way they consider appropriate, students (e.g. through oral distance examinations). Instructors should make sure that, throughout oral examinations, they are not alone with the students being examined.
• Students are required to repeat courses for which they have not received a passing grade. However, whenever a laboratory or exercise is graded independently of a course, it does not have to be repeated, as long as it has been attended successfully.
• A grade correction is allowed, if an obvious oversight or cumulative error has occurred, provided a written request by the instructor responsible has been submitted and approved by the CPS of the IPGS.
• If a student fails to pass the same course more than three (3) times, the procedure defined by the applicable legislation is to be followed.
• Examination papers are kept mandatorily and under the care of the instructor responsible for each course for two (2) years. After this period, examination papers are annulled and are destroyed after a decision has been taken by the CPS and a destruction protocol has been approved – unless a relevant criminal, disciplinary or any other administrative procedure is pending.
• For the calculation of the mark of a degree, the weight of each course in the program of study is taken into account, which is expressed by the corresponding number of ECTS credit units. The number of ECTS credit units of each course is also the weight indicator of this course. For the calculation of the mark of a degree, the grade of each course is multiplied by the corresponding number of credit units (of the course) and the total sum of the individual products is divided by the total number of credit units required for the award of the degree. This calculation is expressed by the following mathematical formula:

Mark of degree = (Σ^Ν_k=1 GC_{k *} CU_k) / TCU

where:

Ν = number of courses required to obtain the degree

GC_k= grade of course k

CU_k= credit unites of course k

TCU = total number of credit units required to obtain the degree.

To obtain a DGS, each student is required to attend and be examined successfully in, depending on the specialization selected, and to prepare and submit a graduate diploma dissertation, thus accumulating ninety (90) ECTS credit units.
