Secondary School

Welcome to the Secondary School

In Secondary school, we prepare our students to engage thoughtfully and responsibly in today’s changing world. We focus on creating learning environments and opportunities that value the world as the broadest context for learning, ensuring that students are exposed to real-world questions and concerns both within and beyond their local contexts. Every lesson in our secondary school is prepared according to our high-quality teaching and learning standards. We see that success is beyond the excellent exam results, and we enrich our curriculum with 21st-century skills. We expect and welcome diversity and promise a broad and balanced curriculum where each learner is taken as a unique individual.

Our highly-qualified and well-motivated teachers are supported by enthusiastic support staff and provide engaging, challenging lessons to bring out the best in all of our students. Our curriculum in KS3 is based on the English National Curriculum and is enhanced by Cambridge Assessment International Education (CAIE) programmes throughout the school. In KS4, students continue their learning journey with the Cambridge IGCSE curriculum. Our students receive support from our career counsellors to choose the most suitable subjects from 22 different subjects offered at this stage. Students complete their studies with the IBDP curriculum in the Sixth-form, which helps them gain internationally recognised and valued qualifications.
