The school year of 180 days is divided into 3 trimesters, beginning in August and ending in June. An active PTA supports the School and encourages parental involvement. The School is also a participating member of the Association of International Schools in Africa. AISM offers a high-quality education similar to that found in private schools in the United States. The curriculum is enriched by Portuguese, music, art, library, computers, and physical education.
English fluency is required.
AISM is fully accredited by the Middle States Association of Colleges and Schools. Enrollment at the beginning of the 1999-2000 school year was 135. Operating expenses are largely financed by tuition fees. Tuition fees are paid on a semester basis. Tuition fees are payable in full for any portion of an academic quarter of attendance.
