The Gymnasium provides its pupils with a broad and in-depth general education and enables them to acquire the general ability to study. It strengthens independent learning and scientific propaedeutic work. In accordance with their abilities and inclinations, the grammar school enables its pupils to focus on individual subjects and enables them to continue their education at a university or in a profession, depending on their qualifications.

Depending on the school's decision, lessons in years 5 to 10 consist of compulsory lessons and optional lessons or compulsory lessons, optional compulsory lessons and optional optional lessons. A second foreign language must be studied from year 6 onwards. Special subject-related teaching focuses can be offered in years 8 to 10. Successful completion of year 10 entitles the student to enter the introductory phase of the upper secondary school (year 11). In the event of leaving school, all lower secondary level qualifications can be acquired depending on the results achieved in year 10.

The gymnasiale Oberstufe is divided into a one-year introductory phase (year 11) and a two-year qualification phase (years 12 and 13), ending with the Abitur examination after 13 school years.

Successful completion of the Abitur examination leads to a general higher education entrance qualification. This entitles the student to take up any course of study at a university, college or university of applied sciences, irrespective of any university admission procedures and admission requirements.

In the event of early departure (at the earliest at the end of the first year of the qualification phase) or failure to pass the Abitur examination, the school-based part of the Fachhochschulreife can be acquired, provided that the minimum requirements are met. The school-based part of the Fachhochschulreife in combination with a vocational part leads to the general Fachhochschulreife. This entitles the holder to study at all universities of applied sciences, at corresponding integrated degree courses at comprehensive universities and, to a limited extent and after individual admission procedures, also at corresponding Bachelor's degree courses at some universities.
