The International Baccalaureate Diploma Programme (IBDP) is renowned for its academic rigor, global recognition, and holistic approach to education. But for many students and parents, one question stands out: How exactly is the IB score calculated?
Understanding the scoring system is essential for tracking progress, setting academic goals, and preparing effectively for exams. This article offers a detailed yet clear explanation of how the IB diploma score works, from individual subject marks to the final diploma decision.
The IBDP score is calculated out of a maximum of 45 points:
42 points come from six individual subjects.
3 additional points come from the Core Components (TOK and EE).
To earn the diploma, students typically need a minimum of 24 points, along with certain other criteria discussed below.
Students take six subjects, usually three at Higher Level (HL) and three at Standard Level (SL). Each subject is graded on a scale from 1 (lowest) to 7 (highest):
A score of 7 reflects excellent performance.
A score of 4 is considered satisfactory.
A score below 4 could put the diploma at risk.
Total subject points possible:
6 subjects × 7 points = 42 points
Subjects are assessed through:
External assessments (mainly final exams, 70–80% of the grade)
Internal assessments (essays, labs, oral presentations, etc., 20–30%)
An interdisciplinary course that examines how knowledge is acquired.
Assessed through a TOK essay and exhibition, graded from A (highest) to E.
A 4,000-word independent research project.
Also graded A–E.
CAS is not graded, but completion is mandatory. Failure to meet CAS requirements results in no diploma awarded.
TOK and EE contribute up to 3 bonus points according to the following matrix:
| Theory of Knowledge (TOK) | ||||||
|---|---|---|---|---|---|---|
| Grade | A | B | C | D | E | |
| Extended Essay (EE) | A | 3 | 3 | 2 | 2 | Failing condition |
| B | 3 | 2 | 2 | 1 | ||
| C | 2 | 2 | 1 | 0 | ||
| D | 2 | 1 | 0 | 0 | ||
| E | Failing condition | |||||
Grades A to E are described as follows:
A = Excellent
B = Good
C = Satisfactory
D = Mediocre
E = Elementary (Fail)
To receive the diploma, students must meet all of the following:
At least 24 total points (including core)
No more than three scores of 3 or below in HL/SL subjects
Minimum 12 points in HL subjects
Minimum 9 points in SL subjects
CAS requirements completed
No E grade in TOK or EE
Failing to meet any of these conditions will result in no diploma awarded, even if the student’s total score is above 24.
Many universities recognize the IB diploma as a gold standard of academic readiness. Higher IB scores can lead to:
Course credit
Scholarship opportunities
Stronger applications for competitive programs
For example:
36+ is typically competitive for top universities.
40-45 is considered outstanding and opens doors to Ivy League or Oxbridge-tier institutions.
Q: Is it possible to pass without scoring a 7 in any subject?
Yes. Most students earn the diploma with a balanced score of 5s and 6s.
Q: What if I fail one subject?
It depends. One low score can be offset by high scores in other subjects, as long as minimum conditions are met.
Q: Do predicted grades count toward my final IB score?
No. Predicted grades are for university applications but do not affect the official IB diploma result.
