Education at O Castro School British International Shool
At O Castro we teach the National Curriculum of England, a system of learning designed to foster curiosity and confidence along with imparting all the necessary skills and knowledge required to succeed in exams and evaluations.
The curriculum is designed to facilitate understanding of the world and the challenges we face. We strive to educate our students to become ethical young people with all the tools they need to succeed in their field of choice.
Immersion in English begins in the Nursery class, complemented by Spanish, French and Galician language lessons as pupils progress through school.
Pupils receive personalised attention to help them thrive and achieve academic success. Senior students are offered a university orientation programme which incorporates mentoring sessions to help them set appropriate goals, and an internship programme to give them a taste of the reality of the world of work.

Where curiosity ignites innovation
The Creativity Lab at O Castro British International School is an innovative, multidisciplinary space that transforms learning through STEAM methodology, advanced technology and collaborative work. Integrated across the British curriculum, it promotes practical education connected to the real world, where students become creators, developing projects from the initial idea to its realisation. Thanks to its flexible design, with areas for presentation, robotics, programming, prototyping and 3D printing, this environment promotes interdisciplinary learning and the development of key skills such as creativity, critical thinking, communication and collaboration, preparing students for the challenges of the 21st century.
An exclusive outdoor learning programme
