What the pass rate measures
- The Diploma pass rate is the share of Diploma students with results who were awarded the diploma, including students retaking it. Students taking individual subjects rather than the full diploma aren't counted.
- A diploma needs at least 24 of the 45 points, and the IB's other conditions must be met as well, so some students with 24 points or more aren't awarded it. In May 2026, 3,846 students with 24 to 29 points weren't.
- The Career-related Programme's pass rate is the share of its students awarded the Career-related Programme certificate.

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.
