Percentage to Grade Calculator

In the Polish school system a 1–6 grade scale is used. The standard thresholds are: 0–29% = 1 (fail), 30–49% = 2 (pass), 50–74% = 3 (satisfactory), 75–89% = 4 (good), 90–97% = 5 (very good), 98–100% = 6 (excellent). Individual schools and teachers may set different thresholds in their assessment policy.

On the standard scale you need at least 30% to receive grade 2 (pass / dopuszczający), which is the minimum passing grade in Poland. Below 30% results in grade 1 (fail / niedostateczny).

On the standard scale, grade 3 (dostateczny) requires a score between 50% and 74%. It represents average mastery of the required curriculum.

Grade 4 (dobry) requires a score between 75% and 89% on the standard scale. It indicates a good command of the curriculum.

The hard scale applies lower thresholds (e.g. 20% is enough for grade 2), rewarding students on difficult tests. The easy scale applies higher thresholds (e.g. 40% needed for grade 2), typically used for simpler assessments.

Yes. Polish education law gives schools and teachers flexibility in setting percentage thresholds. Always check the assessment policy (PSO — Przedmiotowy System Oceniania) for your specific school and subject.

Percentage = (points scored ÷ maximum points) × 100. For example: 36 points out of 50 = 72% → grade 3 (satisfactory) on the standard scale.

Not necessarily. On the standard scale grade 6 starts at 98%, meaning one or two small mistakes do not drop the grade to a 5. The exact threshold depends on the scale chosen.

No. The calculator returns whole numeric grades (1–6). Plus and minus grades are assigned at teachers' discretion and depend on individual school rules that go beyond simple percentage thresholds.

Polish universities typically use a different grading scale (2–5, with half-grades like 3.5, 4.5). This calculator is designed for primary and secondary school grading (1–6). For university grading, check your institution's specific scale.
