International Baccalaureate (Diploma) - Schools offering the International Baccalaureate Diploma (IB Dip) prepare students for university entrance by following the IB programme over the final two years of high school. This involves taking six subjects (three at higher level and three at standard level). Assessment is based on a combination of final examinations and course work that are evaluated by external examiners worldwide, and (in some cases for coursework) by internal assessment. IB examinations for each subject are held on the same days for all students worldwide - in May in the Northern Hemisphere and in October in the case of most Southern Hemisphere schools. Each subject is scored from 1-7, and up to 3 additional points may be awarded for TOK (Theory of Knowledge) essays and for the Extended Essay. A minimum of 24 points is required to obtain the IB diploma, while 45 points is the maximum. A school that has 35 diploma candidates in a given year, out of which 32 passed, has a pass rate of 91%. You can judge the results for yourself by knowing that the world average pass rate is approximately 82%. (Pupils may also opt to take certificates in the individual subject areas, though these on their own may be insufficient for university entry.)

International Baccalaureate Middle Years Programme (MYP)

International Baccalaureate Primary Years Programme (PYP)

Authorised by International Baccalaureate Organization (not to be confused as an inspection or accreditation agency) - International Baccaulareate Organization (by contrast to the US Education turtle of a website, this one goes like a jet and has everything you're looking for right at your fingertips. We know this is a schools guide, but we couldn't help noticing...) The IBO has a very strong system for setting up IB schools and making sure they get off to a good start, but thereafter do not particularly inspect or certify those schools (although they do continue to keep a close eye on schools using their Primary and Middle Years curricula). Instead, they feel the results speak for themselves. Therefore, parents should look at an IB school's exam results and numbers of students qualifying for the IB Diploma: if those numbers are poor or dropping, take a much closer look. If a school is an IB candidate, that's a good sign....but not if it's been a candidate for a decade. Good IB exam and Diploma results do not in themselves tell you about the feel of the school or whether it's right for your child, and no one is looking into every cranny in the same way an American accreditation or Ofsted inspection officer does (not only the academics but also the governance and financial stabilty of a school). But if scores look good, and you like the buzz of the school, there's a good chance you'll find a rigorous programme that will allow a fairly seamless transition from one IB school to another. That is, before the final two year IB Diploma programme. It is very important to note that, in spite of similarities within the curriculum, the two year course is usually regarded by schools as being fairly monolithic. In other words, not made up of identical sequential parts that students can pop in and out of, from school to school, at will. Be aware that the IBO exists to set up curriculum and protocols and they are very good at what they do, but counseling or guiding parents trying to make this transition is not part of their brief.

Council of International Schools (CIS)

Middle States Association of Colleges and Schools (MSACS or MSA) - Although definitely one of the six regional agencies authorised by the US Department of Education (which usually have ACS or CAS at the end of their acronym), this one usually goes by MSA (Middle States Association), or CSS-MSA (Commission on Secondary Schools- Middle States Association).
