IB Assessment Is Set by One Global Body, Not Local Boards
In Japan, as everywhere, the International Baccalaureate Organization is the single assessment body for the Diploma Programme; schools do not choose between competing exam boards the way they might for other systems. The practical decision for families is not which board a school uses but whether it offers the full Diploma, individual DP courses, a Japanese-language DP pathway where available, and the specific higher-level subject combinations a student's intended university course requires.
The IB Diploma is recognised in Japan as a university entrance qualification, but recognition is not the same as automatic admission: each university applies its own eligibility criteria and selection process, which can combine IB scores with essays, interviews or language evidence. Families comparing schools should ask about published subject availability and university counselling record rather than treating any school's DP label as a guarantee that a desired subject combination can be timetabled.
