Katholische Schule St. Marien Oberschule

What Katholische Schule St. Marien Oberschule does

Katholische Schule St. Marien Oberschule is a Catholic secondary school center located at Donaustr. 58, Berlin-Neukölln, founded in 1948 and operated under the formal Trägerschaft (sponsorship) of the Erzbistum Berlin (Archdiocese of Berlin), a public-law corporation. The school combines two German secondary school forms under a single administration led by Schulzentrumsleiterin Frau Rahner (Oberstudiendirektorin i.K.): the Integrierte Sekundarschule (ISS), an integrated secondary school offering qualifications up to MSA and Abitur with full-day care, and the Gymnasium, a grammar school track culminating in the Abitur. Enrollment spans 7th grade through 13th grade, and the school serves approximately 600-900 students (implied from typical Berlin Catholic Ersatzschule scale; exact figure not disclosed). The school has been recognized as 'Schule ohne Rassismus – Schule mit Courage' since December 2020 and completed the GKSI 2.0 Schulinspektion in January 2026.

The school's product portfolio centers on academic secondary education with an integrated stack of support services. Core academic products are the ISS and Gymnasium tracks; ancillary offerings include Ganztagsbetreuung (full-day care) delivered in cooperation with IN VIA Berlin GmbH, Offene AGs and Aktiv-Stunden (extracurricular groups), Schulpastoral (Catholic pastoral care), Beratungsteam and Schulsozialarbeit (counseling and social work), Schülerfirma (student company), Werkstattprojekte (workshop projects), Schulsanitätsdienst (student-run first aid), and Mensa/Cafeteria (catering by Drei Köche, BIO and DGE certified). Technology infrastructure is standard and non-proprietary: the Joomla-based website marienschule-berlin.de (hosted by Quintact - Digital Professionals), the Archdiocese's WebWeaver/Schul-Cloud for parent-school communication, Google Analytics with pseudonymized usage profiles, and YouTube/Google Maps embeds in privacy-extended mode. There are no AI/ML capabilities, proprietary platforms, or app products; the school has explicitly stated it has no app.

The revenue model is that of a German Ersatzschule (state-recognized substitute school): the dominant share of operating funding flows from public per-pupil grants from the Land Berlin, supplemented by Schulgeld (tuition) set according to Archdiocese of Berlin guidelines on an income-based scale with hardship exemptions, plus modest ancillary income from the Förderverein (~240 members paying €25 annual dues), Bildungsspender donations, and canteen operations. Pricing is published as an annual subscription model with an Archdiocese-hosted pre-check calculator. GTM is direct enrollment via the Online Aufnahmeantrag and admissions interviews. Marketing is concentrated in the website, Tag der offenen Tür open days, school events, and the 240-member Förderverein referral network. The customer base consists of Catholic and values-aligned families in Berlin and Brandenburg, with no enterprise or B2B revenue exposure.
