The American-British Academy (ABA), founded in 1987, is one of the premier international schools in the Arabian Gulf region. It is a private, non-profit co-educational day school that offers a demanding K-12 English-language curriculum to expatriate students in Muscat, the capital of the Sultanate of Oman. With more than 62 different countries represented in a school community of around 990 students, the ABA promotes academic excellence within a context of respect for and understanding of cultural diversity. The ABA draws experienced teachers from 22 nations to teach challenging courses and provide a supportive international learning environment for students. Most teachers come from Australia, Canada, the United Kingdom, the United States and New Zealand, but educators from countries in South America, the Middle East, Asia, and continental Europe form a sizeable contingent and all contribute to the international character of the school.
ABA is fully accredited by the Middle States Association of Colleges and Schools and as an "IB World School," authorized by the International Baccalaureate to offer the Primary Years Programme (Grades 1-5). the Middle Years Programme (Grades 6-10) and the Diploma Programme (Grades 11-12).
