"British school" is a description, not a legal category. In continental Europe, no authority prevents a school from using the word "British" in its name, whatever it teaches or however it is run. For parents, the practical question is therefore what independent checks sit behind the label.
Two names come up again and again: COBIS and BSO. They are often mentioned together, and sometimes confused. This guide explains what each is, what each does and does not tell you, and how to verify a school's claims.
What "British" can mean
A British international school typically teaches in English, follows an adapted version of the English National Curriculum, prepares pupils for IGCSE or GCSE at 16 and for A-levels, sometimes the IB Diploma, at 18, and uses English year groups. Beyond that, schools differ widely: some are large, long-established institutions with mainly expatriate pupils; others are small schools with a mainly local intake, and some are branches of UK independent schools.
Because the term is unprotected, the most useful approach is to ask what the school can show you, in writing, from an independent body.
BSO: the government's voluntary scheme
British Schools Overseas (BSO) is the British government's voluntary inspection scheme. Schools outside the UK can choose to take part. The Department for Education (DfE) publishes standards that independent inspectorates use when they inspect schools; the standards were first published on 14 February 2014, revised for the 2017 to 2018 academic year, and the current revised standards came into force on 14 August 2023.
Schools that meet the standards are described as accredited. The DfE publishes a list of accredited schools together with their inspection reports and the date of the latest inspection, and they are registered on Get Information about Schools (GIAS), the department's register of educational establishments in England and Wales. Schools are added after inspection and removed when they close or leave the scheme. One entry the department notes was removed because the college no longer wished to take part.
Three points deserve emphasis:
- It is voluntary. A school that is not in the scheme is not thereby a bad school, but you have one less external reference.
- It is not an endorsement of every aspect of the school. It confirms that the school met the published standards at the time of inspection.
- The date matters. Check when the school was last inspected and read the report, not only the headline outcome.
A government consultation on the scheme proposed aligning the inspection standards with those used for independent schools in England, which indicates the direction of travel: the standards are modelled on English independent school regulation.
COBIS: a membership association
The Council of British International Schools (COBIS) is a membership association for British international schools and organisations. Its home page reports 350 member schools in 86 countries, with 262,000 students and 25,500 teachers; its About page describes member schools across Europe, Asia, Africa, the Middle East and the Americas, together with 200 supporting associates.
COBIS is not a government body and is not an inspectorate. It describes its own scheme as not an inspection regime and not a pass or fail process. Membership is based on one of several routes.
How COBIS membership works
COBIS describes three routes through its own accreditation and compliance scheme:
| Route | What it involves | Result |
|---|---|---|
| Compliance | A three-day visit by a lead improvement partner and another trained representative, covering Standards 1 to 5 (plus 6 for boarding), including areas such as safeguarding, welfare, facilities and governance | COBIS Member (Compliance) |
| Accreditation (one-part) | A four-day visit by a lead improvement partner and a team of three peer accreditors, covering Standards 1 to 10, with observation of learning and teaching | COBIS Accredited Member |
| Two-part accreditation | A compliance visit, followed up to about 12 months later by an accreditation visit | COBIS Accredited Member |
The cycle runs for five years, and membership is valid for five years. According to COBIS, preparation takes about four to six months before a visit, and reports usually follow four to six weeks afterwards.
COBIS also accepts certain external routes to membership: BSO inspections and, subject to approval, accreditation from CIS, WASC and NEASC. This means that a school may be a COBIS member by virtue of having passed a BSO inspection.
BSO and COBIS compared
| BSO | COBIS | |
|---|---|---|
| Nature | Government voluntary inspection scheme | Membership association |
| Body | Department for Education, with independent inspectorates | Council of British International Schools |
| Basis | Published DfE standards | COBIS standards, peer-based review |
| Outcome | Accredited school, listed with report | Compliance or accredited membership |
| Reports | DfE publishes inspection reports | Ask the school to show you the latest report |
| Relationship | COBIS accepts BSO inspection as a route | Does not replace BSO |
The two are complementary rather than competing. A school can hold both, and many do.
What accreditation does not tell you
It is worth being clear about the limits.
- It does not rank schools. Accreditation indicates that standards are met, not that one school is better than another.
- It does not test your child's fit. Culture, pastoral style and peer group are not captured by a standards framework.
- It does not guarantee recognition of qualifications. If a local or national route to university matters, check separately with the examination board and with the universities you are considering.
- It is a snapshot. Leadership changes, rapid growth or financial strain can affect a school after the inspection. Check the date.
How to verify a school
- Ask which scheme or schemes the school belongs to, and since when.
- Check the DfE list of accredited schools and read the latest report, noting its date.
- Check the COBIS membership status on COBIS's own website, and ask which route the school used.
- Ask for the examination centre details, for example the exam boards used and whether the school is itself a registered centre.
- Ask about staffing: how many teachers hold UK qualified teacher status, and what the turnover is.
- Read the report for the safeguarding section first. It is the part that matters most and the one most easily skimmed.
- Talk to parents whose children are in the relevant year.
Questions about the "British" in the name
Some questions are worth putting directly:
- Does the curriculum follow the English National Curriculum, and to what extent is it adapted?
- Which qualifications are taken at 16 and 18, and with which boards?
- How many pupils are British, and how many speak English at home? This affects the language environment.
- How is the local language taught?
- If the school is a branch of a UK school, who is legally responsible for what happens in your child's classroom?
A sensible conclusion
Neither BSO accreditation nor COBIS membership is a mark of excellence. Each is a mark that someone independent has looked. A school that holds one or both, publishes its reports and answers your questions plainly is a better starting point than one that relies on its name. Use accreditation as the first filter, then do what no scheme can do for you: visit, listen, and see whether your child would be happy there.
