St George's International School, Luxembourg

Part of the University of Cambridge. It allows a school to teach the Cambridge programmes and to enter pupils for the exams. There are four stages and they are authorised separately: primary, lower secondary, IGCSE and A Level. If the stages are known they are named in the line below; if that line is missing, the school does not publish them, and the Cambridge registry does not show stages either - it gives only the name of the centre, the country and whether private candidates are accepted. Cambridge calls what it does registration rather than accreditation, and the network holds about ten thousand schools.

What the badge means for this school. The school is allowed to run this programme and to award its certificate. This is a confirmation of the programme, not a judgement on the school as a whole. The entry stands in the organisation's public register - anyone can check it. At this school: IGCSE (ages 14-16), A-Level (ages 16-18). IGCSE means exams at around Year 10 or 11, the British counterpart of a lower secondary leaving certificate. A-Level is the senior years, and their results are what British and many other universities admit on.

A scheme of the UK Department for Education: a school abroad is inspected against the standards for independent schools in England, including safeguarding and the standards for boarding. The inspections are done by independent inspectorates approved by the department, and the inspectorates themselves are monitored annually by Ofsted. The reports are published in full on the government website.

What the badge means for this school. The school has been through this organisation's accreditation. It was judged as a whole: governance, safeguarding, staff, premises, teaching. The entry stands in the organisation's public register - anyone can check it.

An association of British schools abroad with a quality inspection of its own. It has nine membership categories, and the word "accredited" appears in seven of them, although COBIS does its own inspection in one: in the rest it recognises an accreditation granted by somebody else.

It is a head who becomes a member of this conference, not a school: membership is offered to the head, and in some categories the logo is marked as personal. A badge on a school's website means its head belongs to the conference. For full international membership there is a check - two people, two days - but no live external inspection is required.

What the badge means for this school. The school belongs to this network. That is not a quality inspection: a network is something a school joins, while an accreditation is something a school goes through. The entry is confirmed in the organisation's open directory.

A British vocational qualification from Pearson: not an academic course with an exam at the end, but a programme of practical assignments in a particular trade, from engineering and business to art and sport.

What this means for this school. Teaching and assessment work differently from A-level: instead of written exams there is a run of practical assignments marked by the school, while Pearson checks the school itself and samples the work. British universities do accept BTEC, but not all of them and not for every course: level 3 carries the same UCAS points as A-level, and that is what a family aiming at a particular university should look at. For a child who needs the classic academic route, BTEC is not a replacement for A-level but a different path.
