Education without compromise

The ISS is an integral part of the Städtisches Gymnasium Olpe [Olpe Municipal Grammar School] (SGO), the only public high school in the rural urban area of Olpe. With certification as an International School and the IB Diploma program, we offer international students, expat families, and students from the region and beyond a curriculum that is recognized worldwide, as well as the opportunity to earn the International Baccalaureate diploma. In addition to participation in the International Baccalaureate (IB) programme, we also offer bilingual classes from grade 5, bilingual school-leaving qualification and numerous STEM


and language courses that go beyond the curricula and guidelines. Practice-oriented teaching, especially in the fields of STEM, as well as new subjects and topics such as language and literature studies, experimental sciences, individuals and societies, or the arts offer new insights into socially relevant topics. We want to inspire and encourage students to develop and expand their own ideas and interests and to grow into self-determining, cosmopolitan, and responsible individuals with modern educational methods throughout the transition from primary school to the secondary level 2.

Welcome to IB World School

For a strong future

Let's do future

The IB Diploma Programme is intended for secondary 2 level students. With an eye toward an increasingly international and multilingual work environment, we offer our bilingual programme to our students from the 5th grade onward. In the bilingual programme, history, geography, and politics are taught successively in bilingual form. In the upper secondary school there is the option of choosing the bilingual university entrance qualification or the IB Diploma. A good command of English is a basic requirement for the IB. English is the language of instruction alongside German, and English is also the language of the examinations.

The transition to a secondary school is a significant change and challenge for primary school children as well as for their parents. What is the right school? What is the right curriculum? Are we overwhelming our child? These are just a few of the questions parents ask themselves. At SGO and ISS, we offer you numerous opportunities to become acquainted with our school and the programmes we offer, and to meet us in person, even before your enrolment date.

After arrival, orientation, strengthening the classroom community and addressing prevention issues, we focus on the fundamental goals of personality development and the discovery of individual strengths and interests in order to enable your child to successfully complete his or her school career. Therefore, we regularly exchange information with the primary schools about subject content, methods, and techniques so that we can adapt our pedagogical concept to your child's learning experience and prepare him or her in the best possible way for the transition to the upper secondary school.

During the introductory phase, we prepare your child systematically with a special emphasis on the requirements of the qualification phase. Even before the summer holidays, we ensure a good start in the upper secondary school with the summer academy. Whether it is the German university entrance qualification, the Bilingual university entrance qualification, or the International Baccalaureate, we work together to find the best solution for your child by providing extensive support and guidance tailored to the individual needs of each student.

School and leisure time combined
