SEK International School El Castillo is more than a dynamic, IB World School that provides education to international students from 3 months to 18 years old. It is a community where student life is key, where people from diverse cultures and nationalities live, study, and eventually call “home”.

We strive to make our community vibrant and inclusive, where outdoor learning plays an essential role in the learning. We are aware that education does not only take place in the classroom, therefore, SEK-El Castillo International School offers numerous extracurricular and cultural activities that ensure all-round personal and academic development in the area of student life.

SEK-El Castillo offers our students a large variety of extracurricular activities. Our students’ experience is enriched with frequent visits to downtown Madrid, historic cities, and participation in events outside the school premises, providing a unique opportunity to appreciate the local culture. All of this provides an invaluable, unforgettable experience which, without doubt, contributes to student life enrichment and development as global citizens.
