Our History: Where we come from


The non-profit organisation “Initiative für Bildungs- und Begabungsförderung” (Initiative for the Promotion of Education and Talent), which focuses on international education, is founded by the experienced teacher and Head of School Yvonne Wende. Within a year, she also founds the first international preschool for Berlin-Mitte.


The first bilingual English-German kindergarten for Berlin-Mitte opens its doors in September with 18 children. This was the foundation stone for today’s Berlin Cosmopolitan School. Ms. Anita Kreft, who graduated with honours as a dance teacher at the Palucca Schule in Dresden, begins dance lessons with the preschoolers.


The kindergarten grows to 35 children after 6 months.

The music programme of the Berlin Cosmopolitan School begins. “Loving music only works if you are allowed to play music yourself. But that has to happen early on.” (Yvonne Wende)


Helga Helmbold, a lecturer and teacher, founds the European Educational Foundation. Through her generous donation and the great help of Michele V. Adamski, the founding of the Berlin Cosmopolitan School can be initiated.


The BCS Primary School opens with 30 students (grades 1-4) in the building of the Protestant Sophienkirche, Große Hamburger Straße, Berlin-Mitte. We would like to thank the Protestant congregation for their support.


The BCS primary school with now 70 students (grades 1-6) move into the current school building, Rückerstraße 9 in Berlin-Mitte, which was bought by two generous sponsors for the Berlin Cosmopolitan School. The professional dance hall with a large mirror wall is opened with a ceremonial dance performance. All classrooms will be equipped with SMARTboards and internet.


The BCS Gymnasium is launched with 10students for grade 7. Our state-of-the-art science laboratory has opened. The first international student exchanges take place.


There are 130 BCS kindergarten and pre-school children, 170 primary school students and 32 secondary school students (grades 7-8) learning at BCS. Our own sports organisation Central Hoops Berlin Cosmopolitan e. V. is founded. In the same year, our library opens its doors.


In August, the Media Lab, which includes more than 20 computers, is opened. Opening of our second kindergarten and pre-school “Kindergarten in the Park” at Invalidenstraße 130, Berlin-Mitte, with initially 40 children in October.


The school’s own kitchen – a milestone in the history of BCS – is brought to life by the initiative of parents. Together with chef Hartmut Keuchel, chairman of the Berlin-Brandenburg Guild of Gastronomy, and his team, four cooks prepare more than 700 healthy lunches every day – a great benefit for the students and teachers. In addition, a special brunch buffet is offered every morning to the students of the school.


BCS is approved as an International Baccalaureate World School for the Primary Years Programme (PYP) and the Diploma Programme (DP). The first examinations for the Middle School Certificate (MSA) are successfully taken. The Cosmovatorium is launched – an extracurricular music and dance school within BCS. BCS is the first and so far only school in Berlin to offer IB Dance. All classrooms and subject rooms now have interactive SMARTboards, internet, computers, flipcharts, whiteboards and displays.


BCS celebrates its 10th anniversary and receives official state recognition for the Gymnasium (Anerkanntes Gymnasium/ Sekundarstufe II).


The first IB Diploma year successfully completes the programme. We celebrate our first all-school Summer Show, showcasing talent from kindergarten through high school. The High School Art Room is officially opened at 10 Rücker Street. Over 700 students from all over the world study at our Rückerstrasse & Invalidenstrasse campuses.


All IB Diploma and Abitur students are now studying in the new and very modern Upper Secondary Forum at Rückerstraße 8. The first Abitur class graduates from BCS with an excellent grade point average of 1.4 – the best result of any school in Berlin. Congratulations to all the students and teachers who made this possible! The backyard is rebuilt and is now BCS’s outdoor basketball and football court.
