There are four grading systems (or scales) in Greece – four different GPA – one for higher education, one for secondary education, and two for primary education (grades 3 to 4 and 5 to 6).

Primary school

In 1st and 2nd grades in Greek primary schools there is only descriptive evaluation, with no grades included. In the 3rd and 4th grade grades are only letters (Α–Δ) and in 5th and 6th grades numbers ranging from 1–10 are used.

Third and fourth grade

Fifth and sixth grade

Secondary school

The 20-point grading system's range is widened in secondary school.

Gymnasium

Lyceum

The Lyceum school has 32–35 hours per week, with 20-point grading system, Law 4610/2019 The Apolytirio certificate qualification receives an additional final mention (level of distinction) with which it has been earned.

Universities and polytechnics

The table below depicts the Greek Grading system while illustrates approximately how the Grades are compared with ECTS, US and UK grades: For the National Technical University of Athens (polytechnic) the above grades are different: 9–10 is "excellent", 7–9 is "very good", 5–7 is "good", 0–4.9 is "fail". Depending on the school, grade inflation in Greece is rare and it is not uncommon for an examination to be failed—or passed with grade 5—by the vast majority students. Most of the degrees can be equivalent to a bachelor's degree with honours BSc(Hons) / BEng (Hons) since all courses are 4 to 5 years and most of them professionally accredited. All modules, from all years, must be passed with a minimum grade of 5.00 (50%) in order for a degree to be assessed/awarded and there is currently no limit in resits. The classification (Ἀριστα, Λίαν Καλὠς, Καλὠς) is derived from the overall credit-weighted average for all modules including the 'diplomatiki' (university/polytechnic) or 'ptichiaki' (TEI).
