Welcome from the Principal

Welcome from the Principal

Dear families,

It gives me great pleasure to welcome you to SEK Private School El Castillo.

Eloísa López

From 1972, SEK International School El Castillo has offered an exceptional education focused on innovation, professional development and the willingness to adopt new ideas. We are committed to offering our students the best start in life, helping them to access university and enter the working world. We provide them with the skills, knowledge and attitudes that will contribute to their success.

Founded by Felipe Segovia in 1972, the school has played an important role in Spanish education and today we continue to build on that legacy. Therefore, as of this academic year we will be offering the Dual Diploma, an official international Baccalaureate qualification programme that allows students to obtain two simultaneous qualifications, the Spanish Bachillerato and / or the Diploma Programme and the American High School Diploma.

The increase of students and teachers from different nationalities make this school a place for the exchange of intercultural and international experiences. We are also convinced that the arts foster students’ cognitive, creative and emotional development. Which is why we are concentrating our efforts at SEK El Castillo on the artistic programme with the momentum provided by the School of Music and Dance, launched last year to great acclaim and culminating with the awarding, for the first time and this year, of the Arts Baccalaureate.

This pursuit of continuous improvement can also be seen in the work being done on our facilities. Therefore, and coinciding with the celebration of the 25th anniversary of the creation of our Intelligent Classroom methodology, we have renovated and redesigned our Secondary and Baccalaureate learning spaces and our sports centre. We were also delighted to open the Primary Pavilion which has been completely renovated to ensure better acoustics and spaciousness.

Students have the opportunity to travel and study abroad at our schools in Dublin (Ireland) and the French Alps. We also have close ties to Real Madrid and other sporting bodies and federations, leading to the creation of the SEK International Sports Academy, a one-of-a-kind boarding programme in Spain, tailored to helping elite athletes realise their full potential. In this sense, our international boarding halls afford first-class care and support.

The proximity of Camilo José Cela University, sharing a campus with our school, enhances the possibilities of collaboration between school and university, expanding the students’ horizons throughout their academic life.

On behalf of all the school staff and myself, we hope that the following information serves as an invitation to welcome you to visit us in person and see for yourself. We will be happy to assist you and that you choose us to provide the best education for your children.

We are sure that our students will change the future.

Warm regards.

Eloísa López
