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.
- “<10” means the IB didn't publish the exact number because fewer than 10 students took the subject. These figures are never estimated or counted as zero.
- The grade 7 rate is the share of students the bulletin reports at grade 7. The grade 6 or 7 rate is calculated by IBonomics by adding the published shares for grades 6 and 7. Every other figure is as published.
- From November 2023 the bulletins include students who received no grade (N) in each subject's percentages, so grades 1 to 7 add up to slightly less than 100%. Earlier bulletins give percentages of graded students only.
- 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.
