Curriculum details	Curriculum details 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.	Curriculum details —
