Southern International School develops students' diverse abilities through activities to enable them to function with complete autonomy and freedom in today's society. The experience gained from founding and developing a comprehensive educational project supported and encouraged teacher Estela María Irrera de Pallaro to undertake the creation of a new campus in 1999. It was built to enrich institutional objectives in a setting where families find peace, privacy, and a space in contact with nature. With a management and teaching staff committed to ongoing training, the mission is to educate students capable of integrating and interacting in an increasingly complex social environment, where they will need a multitude of tools to navigate successfully. The school has more than a quarter of a century of experience working with students to provide an education that goes beyond academics and aims to form well-rounded individuals.
