The Oporto British School is proud of the fact that it is the oldest British School in mainland Europe, having been established in 1894. It follows a British-style curriculum until the completion of the IGCSE years. The most senior pupils then study the IB Diploma curriculum. The Form 12 pupils have achieved outstanding IB Diploma results in recent years, which have been amongst the best in Portugal. The school, while being conscious of its British foundation and traditions, is very much an international school of the 21st century.
