Nord Anglia International School Rotterdam

A Swiss non-profit, working since 1968. Its programmes are among the most widely recognised school programmes in the world. Authorisation is granted stage by stage, so a school with the final stage does not necessarily run the younger ones; which stages this school holds is set out in the line below.

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: DP (ages 16-19), CP (ages 16-19, with a vocational slant). DP is the final stage, ages 16 to 19: six subjects plus a compulsory core of theory of knowledge, an extended essay and CAS. The diploma is accepted by universities all over the world, and in a number of countries it counts for admission on the same footing as the local leaving certificate. CP is the final stage with a vocational slant, ages 16 to 19: some of the DP subjects plus an applied qualification. It is meant for those heading into a trade or an applied degree rather than an academic one.

It accredits international schools and is a paying association at the same time. It examines governance and ownership, the curriculum, teaching, student wellbeing, staff and premises; a team of volunteers from other CIS accredited schools visits the school. Membership and accreditation are different things here, and schools confuse them more often than anything else.

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 American accreditation working since 1885. For international schools it uses an approach where the visitors look first at live lessons rather than at folders of paperwork: the team works in the school for about a week. It is the only one here whose public directory honestly separates accredited schools from candidates.

International Primary Curriculum: a British primary school programme for children aged 5 to 11. It teaches through themes that draw subjects together rather than through separate subjects; it is published by the International Curriculum Association, formerly Fieldwork Education.

What this means for this school. This is a programme for the primary stage, not an accreditation of the school: the organisation sells it to schools and trains their teachers, but it does not check the quality of teaching at a particular school and keeps no public register of the schools working to it. There is no outside register to check it against, so the entry comes from the school's own words or from the record of its accrediting organisation. The programme has no leaving certificate: at the end of primary school a child moves on to the middle stage, and it is that stage which decides what they finish with.

International Middle Years Curriculum: the continuation of IPC for the middle school, ages 11 to 14. The same organisation and the same thematic frame, only for teenagers.

What this means for this school. As with IPC, this is a programme for one stage rather than an accreditation of the school, and the organisation keeps no public register of the schools working to it. The entry comes from the school's own words or from the record of its accrediting organisation. The programme has no leaving certificate of its own: after it the school takes a pupil on to a final stage - IGCSE, A-Level, IB or a national programme - and that is what to look at.

A group of international schools of the full cycle, day and boarding. The numbers on its site diverge: the "About Nord Anglia" page speaks of 89 schools in 37 countries, the "Our schools" and "Our global network" pages - of 90, the "All schools" page - of "90+"; pupils are more than 100,000 everywhere. Whether the group owns the schools, manages them under contract or gives its methodology under licence is not said on its pages. The year of foundation and the country of registration are not named there.

What this means for this school. The network owns or operates the school. Its accreditation and programme authorisation the school obtains separately, in its own name.
