*Refund and cancellation policy (key points)* - Parents/responsible parties may revoke acceptance of the educational contract without charge within 10 days of acceptance.

Note on items not specified in the published fee materials - The published fee schedule available for the Islands campus lists the monthly cuota amounts above but does not provide a separate numeric value for the registration/matrícula (inscripción) charge or for uniform/textbook package totals in the fee table; those items are referenced contractually but their exact amounts are not shown in the fee sheet I reviewed.

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.
