School Profile


The first English school in Aruba was opened in Seroe Colorado in September 1929. It was owned and operated by Lago Oil and Transport Co. Ltd. to provide for the schooling of the expatriates' children. During the 1960s, the school also opened its doors to dependents of island residents on a tuition basis. With the closing of Lago in 1985, the parents of the remaining students formed the International School of Aruba (ISA), a non-profit foundation, to ensure the continuation of English-language education on the island. In March 2004, the Board of Directors passed the governance and ownership of ISA to International Schools Services (ISS), a not-for-profit organization of Princeton, New Jersey. In April of 2015, ISA celebrated the 85th anniversary of American International Education in Aruba.

School and Community

ISA moved to its new, more central location in the Wayaca Residence area in August of 2005. From this improved position, ISA aims to reach out to more of the island’s population. The campus boasts a turf soccer field (the first in Aruba), beach tennis courts, and a new visual and performing arts wing. There are 215 students enrolled in Montessori through Grade 12. Our students represent 36 different countries. The class of 2018 has 23 students. The teaching staff is comprised of 30 faculty members from 8 different countries with 70% holding advanced degrees.


The school is accredited by Advanced Education. A full successful accreditation review was conducted in April 2018. The Dutch Program is accredited by the Nederlands Onderwijs in het Buitenland (NOB).

Academic Calendar

There are 36 school weeks divided into 2 semesters. Grades are available at the end of each semester. High school students follow a regular schedule- attending each class 4 times per week totaling 220+ minutes. A full-time schedule consists of 7 major classes (1 credit) and 1 minor class (.25 credit).

Academic Program

The curriculum is that of a U.S. university preparatory school. English is the primary language of instruction. Advanced Placement classes are offered in 10+ subjects. AP classes are available to any student who wants to take them. 95% of our graduates go on to universities in North America and other countries. Dutch and Spanish language classes are offered at levels of beginners to native speakers. Dutch exams for CITO, MAVO, HAVO, VWO and CNaVT are conducted each Spring.

Co-Curricular Activities

ISA has a variety of co-curricular activities available to students. Among these are publications, organized clubs, and athletics. Our girls’ soccer program has recently traveled to Jamaica and Italy to compete in international tournaments. Our boys’ basketball team traveled to the Cayman Islands for a tournament.
