What Does Accredited Actually Mean? A Guide to International School Accreditation

You're researching schools and repeatedly see mentions of accreditation:

• CIS
• WASC
• NEASC, COBIS

The school's website probably has a badge in the corner. But what do these letters actually mean, and should they influence your decision?

What Accreditation Bodies Mean

Accreditation is third-party validation that a school meets certain standards. An accreditation body sends inspectors to the school, reviews documentation, interviews staff and students, observes classes, and assesses whether the school meets their criteria. If it does, the school receives accreditation for a set period, usually 5-6 years. After that, the school is re-inspected to maintain accreditation. It's not about perfect schools. It's about schools that meet baseline standards for operations, teaching quality, facilities, and student wellbeing.

CIS stands for Council of International Schools. It's one of the oldest and most widely recognized international accreditation bodies. A CIS accredited school has been reviewed against criteria covering governance, leadership, curriculum, teaching and learning, and student support. CIS accreditation is globally respected and suggests a school has thought through its practices and can defend them to outsiders. Many universities recognize CIS accreditation as a marker of legitimacy.

Major International Accreditors

WASC is the Western Association of Schools and Colleges, a US-based accreditor. It's particularly common for American curriculum schools and schools outside the US that follow American standards. WASC accreditation means the school has demonstrated alignment with American educational standards, curriculum design, and assessment practices. For families planning US university entry, WASC accreditation provides clarity that the school's curriculum aligns with American expectations.

NEASC is the New England Association of Schools and Colleges, another US-based body. It's similar to WASC but operates primarily in the northeastern US and internationally. Some international schools hold NEASC accreditation, particularly those in regions where it's more common or where school founders have New England connections.

COBIS is the Council of British International Schools. If a school is accredited by COBIS, it's been verified to deliver a genuinely British curriculum and meet British educational standards even though it's located abroad. COBIS accreditation is valuable for families wanting assurance that the school follows British approaches to education, assessment, and pastoral care.

How to Use Accreditation Information

EARCOS is the East Asia Regional Council of Schools, a membership association for international schools in East and Southeast Asia. It is not an accreditation body itself; schools must already be accredited (for example by WASC, CIS or NEASC) to join, and membership mainly signals access to a regional network for professional development and student activities.

Other accreditation bodies include

• FOBISIA (a membership network for British international schools in Asia, rather than an accreditor)
• various national accreditation schemes

Some schools hold multiple accreditations, which suggests they meet multiple sets of standards. This is generally positive.

Here's what accreditation doesn't guarantee. It doesn't mean the school is perfect or that every individual teacher is outstanding. It doesn't mean all students will love their time there. Accreditation is a baseline. It means the school has governance structures, follows curriculum guidelines, maintains facilities, and engages in continuous improvement. A freshly accredited school might be wonderful. A school whose accreditation just expired might still be good if they're in the process of re-accreditation, but it's a flag to investigate.

Some countries require accreditation for foreign schools to operate legally. Others don't. This varies by location. A school operating without accreditation might be perfectly fine, or it might indicate regulatory issues. Check what's typical in your country.

How should accreditation influence your school choice? It's a useful quality indicator but not the only one. A school with strong accreditation and zero parent reviews of struggling families gets more weight than an unaccredited school with no transparency. But an accredited school with multiple parent complaints about administration or teaching quality should raise questions despite the badge.

Ask schools about their accreditation directly. When are they accredited through? Have they had any compliance issues? Are they currently in the accreditation process? How did they perform in the last inspection? Most schools are proud of their accreditation and happy to share reports. If a school gets defensive about accreditation or can't clearly explain its status, that's worth noting.

For families moving internationally, knowing a school is accredited by a recognized body provides genuine assurance. Universities understand these credentials. Credit transfers and transcript evaluation become clearer. Your child's diploma will be recognized with less bureaucratic friction. It's one less thing to worry about.
