How the Iran grading scale works
Iranian universities grade each course 0–20; the overall result is the credit-weighted average (moadel) on the 0–20 scale. 17–20 is excellent; the minimum passing grade per course is 10 (often 12 for graduate work).
Grade scale
| Grade / range | Meaning (≈ US) |
|---|---|
| 18–20 | Excellent / Momtaz (A+/A) |
| 16–17.99 | Very Good (A-/B+) |
| 14–15.99 | Good (B) |
| 12–13.99 | Satisfactory (C) |
| 10–11.99 | Pass / Marginal (D) |
| Below 10 | Fail (F) |
Formula
Moadel = sum(course grade x credits) / sum(credits) on 0–20. US band rule (JMU/McGill anchors): 16–20 -> 4.0, 15 -> 3.7, 14 -> 3.0 (B), 12–13.99 -> 2.0 (C), 10–11.99 -> 1.0 (D).
Worked example
A 0–20 average of 16 -> 4.0; a 14 -> 3.0 (B); a 12 -> 2.0 (C) on the US 4.0 scale.
