JGMM

What JGMM does

The Jüdisches Gymnasium Moses Mendelssohn (JGMM) is a state-recognized private secondary school (Staatlich anerkannte Privatschule) located at Große Hamburger Straße 27 in Berlin-Mitte, operated and maintained by the Jüdische Gemeinde zu Berlin (Jewish Community of Berlin). The institution's roots trace to 1862; it was forcibly closed in 1942 under the National Socialist regime and re-established in 1993 as the Jüdische Oberschule before adopting the JGMM name in summer 2012. Today the school operates a dual structure: the JGMM Gymnasium track leading to the German Abitur, and the Rabbinerin-Regina-Jonas-Schule (JONAS), an Integrierte Sekundarschule added in 2020/2021 and named in 2023/2024, providing education from grade 5 onwards.

The school serves approximately 550 Jewish and non-Jewish students, with class sizes capped at a maximum of 24 (smaller at JONAS). Curriculum spans Sekundarstufe I through the Qualifikationsphase and covers MINT (STEM), modern foreign languages, humanities, arts, music, sports, theater, and Judaistik. Distinctive elements relative to mainstream Berlin schools include Hebrew language instruction, Jewish Religious Studies, kosher midday meals, and observance of Jewish festivals — offered to all students regardless of religious background. Extracurricular Arbeitsgemeinschaften (working groups), career orientation (Berufsorientierung), and social engagement programs complement academic coursework.

Revenue is generated through a combination of state funding for the recognized private school and tuition/family contributions, administered under the Jewish Community of Berlin's governance rather than external capital. Go-to-market is event-driven: prospective families engage through the school website, the annual Tag der offenen Tür, and direct enrollment (Anmeldung). The school is part of the Jüdische Oberschulen Berlin network under the Jüdische Gemeinde zu Berlin.
