COLOGNE INTERNATIONAL SCHOOL – a state-approved, IB World School – provides an excellent bilingual, international education from grade 1 through to the IB Diploma or the Abitur (German high school qualification). With a focus on individual care, support and enrichment, we foster the development of core competencies necessary for successfully navigating the world of tomorrow. Throughout our entire school we have a balanced focus on the well-being, personal development and academic growth of each student. Small learning groups, student-centred lessons, international experiences and social action projects are integral elements of our educational concept. Our well-rounded school day includes music, sport, art and world religion, as well as an extensive extracurricular program, enabling students to discover and develop their individual interests and talents.

Primary (grades 1-4)
Our bilingual primary school implements the International Baccalaureate Primary Years Programme (PYP), into which we have integrated the local (NRW) curriculum. We emphasise children’s investigative, research and communicative skills through our transdisciplinary, hands-on approach to learning. Two teachers, one English speaker and one German speaker, work together in mixed-age classrooms (1/2 and 3/4) team-teaching the core subjects, balancing between whole class settings and smaller group differentiation. At the end of primary, our students choose which secondary school form – which learning path – they will join based on the curriculum and qualification most fitting to their personal situation and objectives: the English-language International Secondary School or the German-based Gymnasium bilingual +.

Secondary: International Secondary or Gymnasium bilingual + (grades 5-12/13)
Our International Secondary School offers a combination of Cambridge International and International Baccalaureate programs, leading students to the IGCSEs (grade 10) and the IB Diploma (grade 12). The language of instruction is English, with German as a core subject for both native and non-native speakers. We also offer Spanish and French throughout the school and in the IBDP, give international students the chance to study literature in their own language.

For those families who plan to stay long-term in Germany, the Gymnasium bilingual + offers a high-quality alternative to the German public school system (with Ersatzschule status, meaning it fulfils German public education standards). German is the main language of instruction, however subject content is also taught in English, in addition to English language and literature classes. Students can work towards a bilingual Abitur, or they can opt for a Cambridge English language exam – an external qualification accepted in university and job applications. French, Spanish and Latin are further foreign language options offered from grade 6.

Whichever program our secondary students join – and they can easily move between school forms up to grade 9 – they will be learning and growing in a dynamic and stimulating international environment. An ideal teacher-student ratio guarantees the individual guidance and mentorship that each young person needs, be it in course selection, academic pursuits or personal exploration. Dedicated university and career counsellors additionally support students during the critical phase of their senior years. At the end of their school career, COLOGNE INTERNATIONAL SCHOOL graduates will have developed into internationally-minded, mature young adults, ready to master the global opportunities and challenges that lay before them.

Boarding House
We also offer boarding for 16 students – ages 15-19 – in our modern, fully-furnished boarding house, located a few steps away from the school. Students live in single or double apartments with a shared kitchen, living room and balcony. A pedagogical team provides around-the-clock supervision, guidance and care. Evening meals, weekly meetings, and communal leisure activities offer a familiar and supportive environment, while regular cultural excursions enable students to experience the unique culture in Cologne.

Founded in 2007 in a quiet neighborhood of Cologne-Widdersdorf with 40 students, Cologne International School has continuously grown to the size of 550 students and 115 teachers representing 45 different nationalities. We have the exciting opportunity to move to an up-and-coming business and residential area of Cologne-Butzweilerhof in 2022, and are excitedly planning and designing our new campus with future-oriented learning environments and state-of-the-art facilities. The central location – only a few minutes from the highway exit (A57) and the tram stop (line 5) – allows for easy accessibility. School buses, meals, holiday camps and early/late supervision give families the extra level of comfort and care to be expected from a high quality international school.

Learning support



We understand the function of a school as not only an educational establishment in the traditional sense, but an institution which must foster the development of the whole child. So while academics certainly play a crucial role, we see it as equally important to provide our students with an extensive extracurricular programme. Offers include a wide range of clubs such as orchestra, big band, coding, school sports teams, art, TED Talks, Model United Nations and mother tongue as well as various language options. We also offer students academic support and challenge programmes.
