Accreditation & Membership Glossary

Accreditation bodies evaluate a school's quality on a recurring basis; membership organisations are professional or activity networks a school belongs to. The two aren't the same thing, even though schools tend to list them together.

Accreditation bodies

CIS - Council of International Schools

A global membership and accreditation body for international education. CIS accreditation involves a recurring, in-depth evaluation of teaching quality, governance and student wellbeing - not a one-off certificate.

WASC - Western Association of Schools and Colleges

One of six regional accrediting bodies in the United States. Commonly held by schools following an American-style curriculum, including outside the US.

NEASC - New England Association of Schools and Colleges

Founded in 1885, one of the oldest US regional accreditors. Also commonly held alongside American-curriculum programmes abroad.

Cognia - formerly AdvancED

A US non-profit that accredits primary and secondary schools both domestically and internationally. AdvancED merged into Cognia in 2020, so older school materials may still reference the AdvancED name.

IB World School - International Baccalaureate authorisation

A school authorised to teach one or more IB programmes (PYP, MYP, DP). Authorisation itself is a rigorous, ongoing process specific to each programme a school offers - it isn't a single blanket accreditation.

NCCT - National Center for School Curriculum and Textbook Development

An agency affiliated with China's Ministry of Education. Relevant to schools that teach some or all of the Chinese national curriculum alongside an international programme.

Membership organisations

EARCOS - East Asia Regional Council of Schools

A professional network of English-medium schools across East Asia, focused on teacher training and cross-school collaboration - not an accreditor.

ACAMIS - Association of China and Mongolia International Schools

A regional network of 50+ international schools, best known for inter-school sports and academic competitions.

COBIS - Council of British International Schools

A UK-based membership association for British-curriculum schools operating outside the UK.

APAC - Asia Pacific Activities Conference

An extracurricular sports and activities league of around a dozen international schools across Asia.

A school's own accreditation is listed on its profile page where published.
