How to read COBIS accreditation
What COBIS Patron's Accreditation and Compliance checks, what it doesn't, and why COBIS member and COBIS accredited are two different things on a school website.
The brief
- COBIS is the British-school-specific international accreditation. ~340 member schools, 80+ countries.
- The badge to look for is Patron's Accreditation and Compliance. COBIS membership alone is not the inspection-grade tier.
- The standard has ten standards across two tiers: five Compliance standards (mandatory) and four Accreditation standards on top, plus a sixth boarding standard where it applies.
- The cycle runs five years through evidence-based review, lead-improvement partners, and peer accreditors.
- COBIS is British-curriculum focused. It does not speak to non-British programmes the school may also run, and it is distinct from BSO, which is the UK government's own overseas inspection.
COBIS, briefly
COBIS is the Council of British International Schools. Independent, headquartered at Temple Chambers in London, and founded in 1981 as COBISEC, the Council of British Independent Schools in the European Communities. The "EC" was dropped in 2007 as members spread beyond Europe. Around 340 schools in more than 80 countries sit inside the network today, with roughly 262,000 students and 25,500 teachers.
The accreditation arm is younger than the membership body. COBIS launched Patron's Accreditation and Compliance on 1 April 2017, building on an earlier Accreditation and Compliance scheme that had run since 2014. The "Patron's" in the name is honorific: COBIS named the scheme after its Royal Patron at launch, and the title has stayed with the framework since.
COBIS is unusual in two ways. It is curriculum-specific by design: the standards are written around a British educational ethos, so the protocol speaks to British international schools rather than to all internationally minded schools. And it operates alongside, not in place of, other British inspections: COBIS recognises BSO, ISI, CIS, NEASC and WASC outcomes as routes into its accredited tier without re-running the visit. That is why a British international school will often hold more than one badge.
What COBIS checks
COBIS publishes one set of standards, organised in two tiers. The first five are the Compliance standards, mandatory for every accredited member. Standards seven to ten are the Patron's Accreditation standards, which sit on top. A separate sixth standard covers boarding for the schools that offer it.
| Tier | Standard | What it covers |
|---|---|---|
| Compliance | 1. Safeguarding and safer recruitment | Child-protection policy, recruitment vetting, DBS-equivalent checks, training, designated leads |
| Compliance | 2. Student welfare | Pastoral care, behaviour, anti-bullying, mental health, attendance |
| Compliance | 3. Facilities | Premises, accommodation, health and safety, risk management |
| Compliance | 4. Governance | Board composition, oversight, finance, strategic planning |
| Compliance | 5. Educational ethos and values | British ethos in practice across curriculum and school life |
| Compliance | 6. Boarding | Where applicable: boarding standards, supervision, welfare |
| Accreditation | 7. Learning and teaching | Curriculum, assessment, pedagogy, outcomes |
| Accreditation | 8. Leadership | Senior leadership, school improvement, professional development |
| Accreditation | 9. Communication | Parent and community engagement, reporting, transparency |
| Accreditation | 10. Extra-curricular, enrichment and engagement | Wider opportunities, partnerships, student voice |
Safeguarding sits at Standard 1, and is the area where the bar has tightened most across the international-schools sector. COBIS is a signatory to the International Taskforce on Child Protection. Recruitment vetting, supervision, mandatory reporting across jurisdictions: all in scope, and the area where compliance is most likely to be the sticking point.
What COBIS doesn't check
Whether the maths team next September will be excellent. Whether the head will still be there in two years. Whether the school's American or IB stream is well run, if it also runs one. Whether fees represent good value.
The protocol is British-school-specific. A COBIS-accredited school running both a British and an IB pathway has been verified against the British side, not the IB. The IB programme is governed by its own authorisation through the IBO. The badge is a threshold, not a ranking. COBIS does not order accredited schools against each other.
Member, candidate, accredited
COBIS uses a layered set of categories that school websites often blur. The granular distinctions matter.
| Status | What it means | What it signals |
|---|---|---|
| Provisional School | School is in planning, opening within 1–2 years | Pre-operational. No inspection yet. |
| Candidate | School is working through the COBIS accreditation process | Committed but not yet accredited |
| Member (Compliance) | Verified against Compliance Standards 1–5 | The five mandatory tiers cleared. Not yet the full Patron's badge. |
| Accredited Member (COBIS) | Verified against all ten Patron's Accreditation and Compliance standards | The full COBIS badge |
| Accredited Member (BSO) | Holds a successful BSO inspection within the last five years | UK-government inspection route |
| Accredited Member (CIS / ISI / WASC / NEASC) | Holds another recognised accreditation accepted by COBIS | Route in via another accreditor |
The labels "COBIS school," "COBIS member," and "COBIS accredited" are not interchangeable. The COBIS school directory carries each school's exact category, separate from the school's own marketing.
Four questions a COBIS-accredited school can answer
These are the questions a school holding live COBIS accreditation can answer without difficulty. The answers, or the absence of them, carry information either way.
- Is the school a COBIS Member or COBIS Patron's Accredited? The two are different categories in the same directory. A "COBIS member" line in a school's footer does not, on its own, confirm the inspection-grade badge.
- When was the most recent accreditation visit, and when is the next scheduled? The cycle is five years. A school six months past a clean visit and a school whose accreditation is up for renewal are in different positions.
- Will the school share the visit summary, or at least its commendations and recommendations? COBIS does not publish the reports; the schools do.
- What three things changed after the last visit? The output of an accreditation cycle is the action plan, not the badge.

FAQs
Is COBIS the same as British Schools Overseas (BSO)?
No. BSO is the UK Department for Education's own inspection scheme for British schools abroad, delivered by approved inspectorates such as ISI, Penta International, Cambridge Education, and the Schools Inspection Service. COBIS Patron's Accreditation is a peer-led scheme run by the COBIS membership body. A school may hold both. COBIS accepts a recent successful BSO inspection as a route into its Accredited Member tier without a separate COBIS visit.
How long does COBIS accreditation last?
Five years. The cycle is built around supportive dialogue with COBIS-appointed Lead Improvement Partners and Peer Accreditors rather than a one-off pass/fail snapshot. Schools submit and refresh evidence across the cycle, with a full review at renewal.
Can a school lose its COBIS accreditation?
Yes. Accreditation can be deferred, suspended, or withdrawn if mandatory Compliance standards are not met, if a safeguarding failure comes to light, or if the school exits membership. COBIS does not publish a public list of withdrawn schools.
Is COBIS recognised by UK universities and UCAS?
Indirectly. UCAS and UK universities recognise the British qualifications a COBIS school delivers (IGCSE, A Level, BTEC) through the relevant exam boards, not through COBIS itself. The accreditation gives admissions teams confidence that the school administering those qualifications is operating to a British standard, which can reduce friction for less-known schools.
Is COBIS Patron's Accreditation the same as ISI or BSO?
No. ISI is the Independent Schools Inspectorate, the body that inspects UK independent schools and delivers most BSO inspections on behalf of the DfE. BSO is the UK government's overseas inspection regime. COBIS Patron's Accreditation is the accreditation arm of the COBIS membership body. The three speak to overlapping but distinct evidence sets, which is why some British international schools hold more than one.
