IB Computer Science Grade Distribution

Latest data: May 2026Provisional

In May 2026, 34.4% of IB Computer Science HL students and 27.4% of SL students got a 6 or 7. The most common grade was 5 at HL (25.2%) and 3 at SL (21.3%).

Compared with May 2025, the grade 6 or 7 rate was up from 29.0% at HL and up from 24.1% at SL.

Percentage of students at each grade, as published. The grade 6 or 7 rate is the two shares added.

  • These bulletins print no N (no grade) column, so grades 1-7 are shares of the students who received a grade, and N is shown as —. (November 2021, May 2022, November 2022, May 2023)
  • These bulletins include N (no grade) in the total, so grades 1-7 add up to less than 100% and are measured on a slightly different basis from sessions without an N column. (November 2023, May 2024, November 2024, May 2025, November 2025, May 2026)
  • Grade cells the bulletin leaves blank are shown as 0.0%. (November 2021, May 2022, November 2022, May 2023, May 2024, May 2025)
  • The IB states that these results combine examination and non-examination assessment routes, which were used during the COVID-19 disruption. (May 2022)

Change: the difference from the same session a year earlier, May from May and November from November, in percentage points.

—: no result for that session, or none a year earlier to compare it with.

Grade shares from November 2023 count students with no grade (N) and earlier ones don't, so changes across that point aren't shown.

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.
  • “<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.
