The American International School in Abu Dhabi is celebrating its 25th anniversary, having been established in 1995 to provide local and expatriate residents of Abu Dhabi with high quality American education, based on American standards and an international curriculum. AISA received its first accreditation in October 1997 from the Middle States Association of Schools and Colleges (MSA), and in January 2010 was accredited by the Council of International Schools (CIS). AISA offers education from Kindergarten to Grade 12. It was the first school to offer the International Baccalaureate Diploma in the UAE and later became the first school in Abu Dhabi to be authorized to offer the IB Primary Years Program (PYP). In keeping with local regulations, the Secondary School is gender segregated.
