As a non-profit school, AISZ is committed to operating with transparency and accountability to our community. Our Annual Report provides a comprehensive overview of the school's academic performance, financial health, strategic progress, and community highlights each year.
AISZ is accredited by the Middle States Association of Colleges and Schools (MSA/CESS) and is an authorised IB World School. These accreditations are not awarded once and forgotten — they require ongoing review, self-evaluation, and a demonstrated commitment to continuous improvement. They are among the most rigorous and respected quality standards in international education.
In 2025, AISZ was also recognised as a Model PLC at Work School — an acknowledgement of our commitment to collaborative professional learning and evidence-based teaching practice.
AISZ is proud to be connected with the following organisations:
ECIS — European Council of International Schools
CEESA — Central and Eastern European Schools Association
