Polish schools often use a percentage scoring system for tests. Teachers award points and then convert them to grades according to an established scale. Learn about the most popular conversion tables and find out what grade corresponds to a given percentage.
After taking a test, you receive a certain number of points, e.g., 23 points out of 30 possible.
The teacher calculates what percentage of maximum points you earned: 23/30 = 0.77 = 77%
Then, according to the established percentage scale, they assign a grade, e.g., 77% = grade 4 (good)
Each school and teacher may use a different conversion scale. There is no single standard for all schools in Poland.
Below you'll find the most commonly used conversion tables in Polish schools.
- 100% = 6 (excellent)
- 90-99% = 5 (very good)
- 75-89% = 4 (good)
- 50-74% = 3 (satisfactory)
- 30-49% = 2 (passing)
- 0-29% = 1 (failing)
- 95-100% = 6 (excellent)
- 85-94% = 5 (very good)
- 70-84% = 4 (good)
- 50-69% = 3 (satisfactory)
- 30-49% = 2 (passing)
- 0-29% = 1 (failing)
- 98-100% = 6 (excellent)
- 90-97% = 5 (very good)
- 75-89% = 4 (good)
- 60-74% = 3 (satisfactory)
- 40-59% = 2 (passing)
- 0-39% = 1 (failing)
The matura exam has a different scale than regular school tests. The passing threshold is 30%.
- 91-100% = very high result
- 71-90% = high result
- 51-70% = average result
- 30-50% = satisfactory result (passed)
- 0-29% = not passed
Similar percentage thresholds, but the difficulty level is higher.
Important: Matura results are not converted to school grades 1-6, only determining whether the exam was passed (≥30%) and in which percentage range the result falls.
Some schools use more detailed scales with pluses and minuses, e.g.:
- 87-89% = 5- (very good minus)
- 90-94% = 5 (very good)
- 95-97% = 5+ (very good plus)
The use of pluses and minuses is not legally regulated and depends on school policy.
- Check the school statute or Subject Grading System (PSO)
- Ask the teacher before the test about the scale used
- Check the electronic gradebook – some systems show the scale with grades
- The scale may differ for different subjects and teachers
- Always ask the teacher about the scale before an important test
- If you're close to a higher grade threshold (e.g., 74%), you can try negotiating an extra point
- Rounding results (e.g., 74.5% → 75%) depends on the teacher – it's not a rule
- Some teachers lower thresholds for difficult tests
