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.
