How It Works
The IB Diploma Programme requires students to take 6 subjects: 3 at Higher Level (HL) and 3 at Standard Level (SL). Each subject is graded from 1 (lowest) to 7 (highest), giving a maximum of 42 subject points.
In addition, students complete Theory of Knowledge (TOK) and an Extended Essay (EE), each graded from A to E. The combination of TOK and EE grades determines bonus points (0-3), bringing the total possible score to 45.
A minimum of 24 points is needed for the Diploma, with additional conditions on individual subject grades and HL/SL point minimums. An E in either TOK or EE can result in Diploma failure.
TOK/EE Bonus Matrix
| TOK \ EE | A | B | C | D | E |

| B | 3 | 2 | 2 | 1 | F |
| C | 2 | 2 | 1 | 0 | F |
| D | 2 | 1 | 0 | 0 | F |
| E | F | F | F | F | F |
F = Failing condition (Diploma not awarded)
Frequently Asked Questions
What is the maximum IB score?expand_more
The maximum IB Diploma score is 45 points. This consists of a maximum of 42 points from 6 subjects (each graded 1-7, so 6 x 7 = 42) plus up to 3 bonus points from the Theory of Knowledge (TOK) and Extended Essay (EE) matrix.
What score do I need to pass the IB Diploma?expand_more
To be awarded the IB Diploma, you need a minimum of 24 points overall. You must also meet several conditions: no grade 1 in any subject, no more than two grade 2s, no more than three grade 3s, at least 12 points from Higher Level (HL) subjects, and at least 9 points from Standard Level (SL) subjects.
How does the TOK/EE bonus matrix work?expand_more
The TOK and EE are each graded A to E. Your combination of grades determines your bonus points (0 to 3). For example, A in both gives 3 bonus points, A and B (either way) gives 3, B and B gives 2, and so on. If you receive an E in either TOK or EE, you may fail the Diploma regardless of your other scores.
