How the IB Grading System Works (1–7 Explained)
The IB scoring system confuses many students and parents at first. Here is a clear breakdown of how the points add up and what the numbers actually mean.
Each subject is graded 1 to 7
You take six subjects, each graded from 1 (lowest) to 7 (highest). A 7 represents top-band performance. Three or four subjects are taken at Higher Level (HL) and the rest at Standard Level (SL).
The 45-point total
Six subjects give a maximum of 42 points. The final 3 'core' points come from Theory of Knowledge (TOK) and the Extended Essay (EE) combined, making the maximum total 45.
A score around the high-30s is strong; 40+ is excellent and competitive for top universities.
Passing the Diploma
To earn the full Diploma you must meet a minimum points total and satisfy specific conditions across HL/SL subjects, TOK, the EE, and CAS. Your school will confirm the exact requirements for your cohort.
- Don't neglect TOK and the EE — those core points are easy to underestimate
- A balanced profile across subjects is safer than relying on one strong score
How to push toward a 7
Top scores come from mastering command terms, exam technique, and the internal assessments — not just content. Targeted practice and feedback are the fastest route up the scale.
