Santo António International School (SAIS) is an International Independent Catholic School located in the heart of Monte Estoril, near the historical Villa of Cascais in the Lisbon District area. Our aim is to combine academic excellence with a caring family environment. Significant global change demands a different way of thinking about ourselves and the world around us. International education has an approach to learning that is focused on critical thinking which helps students to successfully perform in varied intercultural contexts. Santo António International School's approach also includes the development of multidisciplinary communication skills.
