The 40–45 shares for November 2021 (from the November 2025 bulletin), May 2022 (from the May 2026 bulletin) and November 2022 (from the November 2025 bulletin) are from later bulletins, which reprint them as one band. Those sessions' own bulletins print 40–44 and 45 separately.

How the IB score works

  • The Diploma score is out of 45: up to 7 points in each of six subjects, and up to 3 core points for Theory of Knowledge and the extended essay.
  • A diploma needs at least 24 points, and the IB's other conditions must be met as well.
  • The average score includes every Diploma student with results, those not awarded the diploma among them, so it is lower than the average of those awarded it.

Source and methodology

These statistics are from the International Baccalaureate's statistical bulletins. The latest data shown is from the May 2026 assessment session.

About this data

  • May and November are separate assessment sessions. November is much smaller and mostly taken by schools in the southern hemisphere, so its figures aren't directly comparable with May's.
  • The May 2026 figures are from the IB's provisional bulletin and may change when the final bulletin is published.
  • Older bulletins call the people sitting the exams “candidates” and newer ones “students”. This site says “students” throughout.
  • Bulletins up to May 2023 print figures to two decimal places and later ones to one. Each figure is shown as printed, and changes are compared at the lower precision.
