Oak House School opened in 1968 in Barcelona, Spain and has since grown to 950 students while maintaining a family atmosphere and focus on students' academic, social, and emotional development. The school blends elements of the English and Catalan education systems in its curriculum. While it must comply with requirements of both systems, Oak House also offers the International Baccalaureate program and Cambridge IGCSE exams to students. The school has added new programs like the IB Diploma and is constructing a new building, while also seeing increased enrollment despite economic challenges through strict cost control.
