Convert Percentages to Grades - Belgian System (0-20)

Learn how to convert percentages to grades on the Belgian 20-point scale.

In Belgium, schools and universities use a scale from 0 to 20. Converting percentages to this scale is simple: you divide the percentage by 5. Here we explain how it works.

The Standard Conversion (percentage to /20)

The basic formula is simple: grade = percentage / 5. This gives the following scale:

  • 100% = 20/20 (exceptional, almost never given)
  • 90% = 18/20 (excellent)
  • 80% = 16/20 (great distinction)
  • 70% = 14/20 (distinction)
  • 60% = 12/20 (satisfaction)
  • 50% = 10/20 (sufficient, passed)
  • 40% = 8/20 (insufficient)
  • 30% = 6/20 (insufficient)
  • 20% = 4/20 (weak)
  • 10% = 2/20 (very weak)

In Belgium, 10/20 (50%) is the passing threshold. Grades above 16/20 are rare and above 18/20 are very exceptional.

The Formula Explained

To convert a percentage to a grade out of 20:

Grade = Percentage / 5

Example: You score 75% on a test. Your grade is: 75 / 5 = 15/20 (distinction)

The Passing Threshold (cesuur)

In Belgium, the passing threshold is at 50%, which corresponds to 10/20. This is different from the Netherlands where 55% is often required.

If you score 48%, you get 9.6/20 which rounds to 10/20 - but note: some teachers only round at the final grade.

Tip: Always ask your teacher how rounding works. This can vary by subject or school.

Differences by School

Schools may apply small variations:

  • Some schools give half points (e.g., 13.5/20)
  • Other schools always round to whole numbers
  • Different rules may apply to exams than to daily tests
