Turkish University GPA — 4.0 Scale and Letter Grade Conversion
Turkish universities use a double-letter grade system (AA through FF) mapped to a 4.0 GPA scale and derived from 0–100 percentage marks. The Council of Higher Education (YÖK — Yükseköğretim Kurulu) governs the framework and requires a minimum cumulative GPA of 2.0 for undergraduate graduation. This page documents the full grade-to-GPA mapping table, YÖK requirements, and how OpenEduCat automates Turkish university grading.
Turkish University Grade-to-GPA Mapping Table
Standard YÖK-aligned double-letter grade scale used across Turkish public and private universities. Exact percentage boundaries may vary by institution.
| Letter Grade | Percentage Range | GPA Points | Turkish Performance Label | International Equivalence |
|---|---|---|---|---|
| AA | 90–100 | 4.0 | Pekiyi (Excellent) | Equivalent to A on US 4.0 scale |
| BA | 85–89 | 3.5 | İyi-Pekiyi (Very Good) | Equivalent to A-/B+ on US scale |
| BB | 80–84 | 3.0 | İyi (Good) | Equivalent to B on US 4.0 scale |
| CB | 75–79 | 2.5 | Orta-İyi (Good-Average) | Equivalent to B-/C+ on US scale |
| CC | 70–74 | 2.0 | Orta (Average) | YÖK minimum pass for graduation eligibility |
| DC | 65–69 | 1.5 | Zayıf-Orta (Below Average) | Conditional pass; may require retake in some programmes |
| DD | 60–64 | 1.0 | Zayıf (Weak) | Minimum passing grade; affects CGPA significantly |
| FD | 50–59 | 0.5 | Çok Zayıf (Very Weak) | Fail at most universities; some use as conditional fail |
| FF | Below 50 | 0 | Başarısız (Failed) | Fail — course must be retaken (Bütünleme eligible if ≥40%) |
| NA | N/A | 0 | Devamsız (Absent) | Fail due to insufficient attendance; no Bütünleme eligibility |

YÖK Requirements for Turkish Universities
The Council of Higher Education (YÖK) sets the minimum standards for GPA computation and graduation at all accredited Turkish institutions.
Minimum Graduation CGPA
YÖK (Yükseköğretim Kurulu — Council of Higher Education) sets the minimum CGPA for graduation at 2.0 on the 4.0 scale for undergraduate programmes at all accredited Turkish universities.
Letter Grade Scale
YÖK recommends the double-letter grade system (AA, BA, BB, CB, CC, DC, DD, FD, FF) mapped from the 100-point percentage scale. The exact percentage boundaries may vary by institution within the YÖK framework.
Credit-Weighted GPA Calculation
The CGPA (Genel Not Ortalaması or GNO) is computed as the credit-weighted average of grade points across all registered courses. Failed courses (FF, FD, NA) contribute 0 or 0.5 grade points and significantly depress the CGPA.
Academic Probation
Students whose CGPA falls below 2.0 at semester end are typically placed on academic probation (koşullu durum). Probation restricts credit load and requires improvement within a specified number of semesters. YÖK sets maximum programme duration at 2× standard duration.
