An international school teaches in English, follows an internationally recognized curriculum, and specifically prepares students for universities worldwide, while a regular German school teaches in German, the national language. Qualifications such as the Cambridge International General Certificate of Secondary Education (IGCSE) or the International Baccalaureate (IB) Diploma open doors all over the world, regardless of which country the family lives in next or where the child wants to study. The school community, teaching style, and university preparation also differ.
Many parents wonder what this difference means in concrete terms. Below, we answer the most important questions parents have on this topic.
What Distinguishes an International School From a Regular German School?
An international school is an educational institution that teaches mainly in a language other than the national language and follows an internationally recognized curriculum. In Germany, this usually means lessons in English, combined with German as a required subject and additional foreign languages.
What distinguishes an international school from a regular school is not just the language, but also the makeup of the school community. Students from dozens of nations learn together, bring different perspectives, and grow up in a multicultural environment. This shapes the way they think, communicate, and interact with others.
International schools are aimed both at families who have moved here from abroad and at German-speaking families who want to give their children an internationally oriented education. Everyday school life is often more structured and academically demanding than at many regular schools.
Which Qualifications Can My Child Earn at an International School?
This is one of the most common questions from parents considering an international school. The answer depends on the individual school, but two qualifications are particularly widespread and internationally recognized:
- Cambridge IGCSE: Students prepare for the International General Certificate of Secondary Education in grades 9 and 10 and take the exams at the end of grade 10. British universities look closely at these results in admissions, but American and international universities also take them into account. If your child is aiming for the German lower secondary qualification (Sekundarabschluss I, or Mittlere Reife), you can contact the Bezirksregierung Düsseldorf (district government) directly.
- IB Diploma: The International Baccalaureate Diploma is completed in grades 11 and 12. It is considered one of the most demanding school-leaving qualifications in the world and is recognized by universities in Europe, the Americas, Asia, and beyond. Students who successfully complete the IB Diploma can use it to obtain the general university entrance qualification (Allgemeine Hochschulreife) in Germany.
Both qualifications require students to demonstrate solid knowledge in several subjects and at the same time prove skills such as critical thinking, independent research, and time management.
What Are the Biggest Differences in Everyday Teaching?
Compared with a regular German school, one thing in particular stands out at an international school: teaching is more strongly focused on individual support. Learning gaps are identified early, often through regular progress checks, and closed in a targeted way.
Another difference is the language of instruction. At an international school, children learn all core subjects in English, which significantly strengthens their language skills. German is taught as a required subject, often in separate groups for native speakers and learners of German. From a certain grade onward, a third language is added, for example French, Spanish, Japanese, or Chinese.
The makeup of the classes also differs: when children work together every day with classmates from many different cultures, they naturally develop an open-minded worldview and intercultural competence. This is not a curriculum goal on paper, but part of everyday school life.
Which Children Is an International School Suitable For?
An international school is not only suitable for children from abroad. It is a good choice for all families who value a demanding, multilingual, and future-oriented education.
An international school is a particularly good fit for children who:
- are growing up in an English-speaking environment or already have some English skills
- live in a family that may move abroad or has already moved several times
- are looking for a high level of academic challenge and are motivated to do their best
- would like to benefit from a multicultural school environment
What matters is that children are open and eager to learn. Lessons in English can take some getting used to at first, but most students find their way quickly, especially when the school offers individual support.
How Does an International School Prepare Students for University?
This is one of the greatest advantages of an international school: preparation for university does not begin in the upper school, but runs throughout the entire school career. The IB Diploma, for example, requires students to:
- Write an extensive research paper, the Extended Essay (EE)
- Complete a creativity and service project, known as Creativity, Activity, Service (CAS)
- Think critically about how we acquire and evaluate knowledge in Theory of Knowledge (TOK)
These skills are needed every day at university.
What University and Career Counseling Do International Schools Offer?
Many international schools also offer professional counseling on university and careers. This means:
- Personal conversations with university counselors
- Help with application materials
- Contacts with universities worldwide
- Support with career orientation
As a result, students know early on what options they have and how best to prepare.
What Accreditations Should an International School Have?
Not every school that calls itself international is also officially recognized. When choosing a school, parents should look for specific accreditations that show that a school is regularly reviewed externally and meets certain quality standards.
The most important accreditations include:
- IB World School: Authorized to offer the International Baccalaureate Diploma Programme and other IB programs.
- Cambridge Examination Centre: Authorized to administer official Cambridge examinations, including the IGCSE.
- Cognia accreditation: An internationally recognized quality certification for schools that includes regular external evaluations.
- CIS membership: The Council of International Schools sets high standards for international schools worldwide.
- State recognition: In Germany, it is important that an international school is recognized by the relevant federal state as a supplementary school (Ergänzungsschule) or a substitute school (Ersatzschule).
These accreditations are not bureaucratic formalities. They are a promise of quality to the families who entrust their school with what matters most: their children’s education.
