History	History In 1981, in a stately house on O'Higgins Street in the Belgrano neighborhood, inspired by teacher Estela María Irrera de Pallaro and with the support of her husband Andrés Pallaro, a kindergarten was founded that later became Islands International School. Years later, with much effort, clear goals and dedication, the primary school came to life, today located in a large building on Virrey del Pino and Arcos Streets. In 1988, closely following the most advanced programs in Argentina and the world, the secondary section was created, currently located on Amenábar Street. A building was constructed with the spaces and equipment necessary to meet the needs of a modern education. In 1990, Islands also included the International Baccalaureate in its programs, a prestigious association of schools based in Geneva, Switzerland. One of the most important objectives is to promote the integral development of students so that they can harmoniously acquire the skills needed for admission to higher education and, consequently, to the increasingly demanding world of work. Therefore, it is important that they achieve fluency in Spanish, English and Italian. Passing the International Baccalaureate diploma also means that students obtain the Maturità Linguistica o Scientifica, a qualification recognized by the Italian Government as completion of secondary education and acceptance to university at the European level.	History Drawing on extensive experience in founding and developing a comprehensive educational project, Estela María Irrera de Pallaro undertook the creation of a new campus in 1999. The campus was built to enrich institutional objectives in a place where families not only find peace and privacy but also a space in contact with nature. With a management and teaching staff continually trained, the mission is to educate students capable of integrating and interacting in an increasingly complex social environment, where they will need a myriad of tools to function successfully. The school has more than a quarter of a century of experience shared with students, drawing on them to provide an education that addresses academics and also aims to form well-rounded individuals. Southern International School develops students' diverse abilities through activities that enable them to develop with complete autonomy and freedom in today's society.
