NEASC is an independent, voluntary, non-profit membership organisation that accredits over 1,500 public, independent, and international schools worldwide. While headquartered in the United States, its Commission on International Education (CIE) is a key accrediting body for international schools, including many British international schools and UK-based independent schools offering American or international curricula (such as the IB). The association functions through a peer-review process to ensure institutions meet high standards of educational quality, aiming to foster continuous school improvement and innovation rather than simple compliance.
