Choosing the International Baccalaureate Diploma Programme (IBDP) is a significant step towards studying at world-class universities. However, many students and parents often wonder how the IB grading system works. What does it mean to score a 7 or a 3? How many points do you need to earn the diploma? What IB exam scores are considered good?
In this blog, we will give you a full breakdown of the IB grading scale, how IB points are calculated, what the grades mean, and how they compare with other qualifications like A-Levels and AP.
Understanding the IB Grading Structure
The International Baccalaureate grading system is designed to evaluate both academic understanding and critical thinking. Here is how the IB grading scale works:
- Students choose six subjects in total
- Three subjects must be studied at a Higher Level (HL)
- Three subjects must be studied at Standard Level (SL)
- Each subject is graded on a scale of 1 to 7
- There are three extra points available from the core components
All the above points bring the total possible score to 45 IB points.
Explanation of IB Grades 1–7
Here is an easy-to-follow explanation of the International Baccalaureate grades 1-7:
- 7: Excellent performance with a complete understanding of the subject
- 6: Very good grasp of the subject with few mistakes
- 5: Good performance with a consistent understanding
- 4: Satisfactory, meets minimum expectations
- 3: Mediocre, shows limited achievement
- 2: Poor, needs improvement
- 1: Very poor; severe lack of understanding
International Baccalaureate grades are based on internal assessments (such as projects and research work) and final external exams.
What Makes Up the Final IB Score?
The final International Baccalaureate scores are made up of:
- Up to 42 points from 6 subjects (each worth 7 points)
- Up to 3 points from the core: Theory of Knowledge (TOK) and Extended Essay (EE)
The third core component, Creativity, Activity, Service (CAS), must be completed, but it is not scored.
To pass the diploma:
- You must earn at least 24 out of 45 points
- At least 12 points should come from HL subjects
- At least 9 points should come from SL subjects
- You need at least a E grade in both TOK and EE
The core components of IBDP include:
Theory of Knowledge (TOK)
- Focuses on understanding how knowledge is formed
- Includes a 1,600-word essay and a presentation
Extended Essay (EE)
- A 4,000-word research essay on a topic of interest
Creativity, Activity, Service (CAS)
- Encourages real-world learning outside the classroom
Average IB Scores Around the World
Every year, the International Baccalaureate Organisation releases data showing how students perform globally. In 2023:
- The global average was 29.1 out of 45
- Only 9.7% of students scored 40 or above
- The highest average subject scores were in Language Acquisition (5.2)
- The lowest was in Mathematics (4.0) and Sciences (4.3)
These scores reflect the rigorous nature of the IBDP and the high standards expected.
IB Grading System - What is a Good IB Score?
This depends on your university and career goals. Here are some general benchmarks:
- 24: Minimum passing score
- 28–30: Decent and accepted by many universities
- 34–37: Competitive for many top global universities
- 38–40: Very strong, open doors to top-tier universities
- 41–45: Exceptional, required by Ivy League and elite universities
Only about 1.1% of students get a perfect score of 45. But most universities don’t expect perfection. For example:
- University of Amsterdam: 34 points
- EPFL, Switzerland: 32 points
- University of Manchester: 30–39 points
- McGill University, Canada: 37 points
Universities also consider extracurriculars, essays, recommendation letters and subject-specific performance.
How IB Points are Calculated
Students and parents often use tools like an IB score calculator to estimate final scores. These calculators help predict your total based on your internal assessments, predicted grades and mock exams. It gives a realistic idea of what to expect.
How to Convert IB Points to Percentage
There is no universal rule for converting IB points to a percentage, but here is a general idea:
- 7 = 96% to 100%
- 6 = 86% to 95%
- 5 = 76% to 85%
- 4 = 66% to 75%
- 3 = 56% to 65%
- 2 = 46% to 55%
- 1 = Below 45%
These are just approximations and can vary between subjects.
IB Compared to Other Systems
The IB is recognised globally, but what does a seven mean in other systems?
- A-Levels (UK): A score of 7 is equal to an A*
- Advanced Placement (USA): A score of 7 matches a 5, the top score in the USA
- French Baccalaureate: A score of 7 is comparable to a score of 20/20
Still, there is no official conversion between IB and these systems. Many universities use UCAS points or their assessment methods.
What Do Experts Say About the IB Exam Scores
According to the experts on university applications:
- IB grades are on par with the top grades in A-Levels and AP
- Students should focus on subject-specific performance and overall balance
- Universities value the holistic nature of the IB curriculum

- Discuss tough topics with classmates or teachers —Explaining things to others also helps you understand better.
- Sleep well and eat healthy—A fresh mind and energised body make a huge difference in learning and performance.
