The KMK formula: how is the Abitur grade calculated?
The nationwide standard conversion of points into a grade
The Abitur grade — the final grade point average of the German university-entrance diploma — is calculated across all German states using a uniform formula set by the Standing Conference of Education Ministers (KMK): N = 17/3 − E/180. Here, E is the total point score from Block I and Block II. The formula ensures that 900 points (the maximum) correspond to grade 1.0 and 300 points (the minimum) to grade 4.0. Below 300 total points, the Abitur is considered failed.
The Block I covers the school performance from the qualification phase. Depending on the state, between 22 and 40 courses are counted, of which a certain number must be included. Each course can score a maximum of 15 points. Block I can total up to 600 points. The Block II contains the results of the final Abitur examinations — usually 4 to 5 exams (written and oral) with a maximum of 60 points each, giving a maximum value of 300 points.
A crucial technical detail: the grade is truncated to one decimal place by the formula — not rounded. A calculated grade of 2.09 therefore becomes 2.0, not 2.1. This can make the difference between two grade levels at borderline point totals. From 823 total points onward, the grade is automatically capped at 1.0.
It is important to understand that only the conversion of points into a grade is standardised nationwide. How the points in Block I and Block II are arrived at — how many and which courses are counted, whether bonus points exist for special achievements — varies considerably from state to state. A direct comparison of final grades between students from different states is therefore only meaningful to a limited extent.
