IB Grades Explained - TutorChase (2024)

The International Baccalaureate (IB) is a rigorous academic programme offered to students in over 150 countries around the world. It is known for its high standards and challenging coursework, and the grading system can seem daunting at first. However, once you understand how the IB grading system works, it becomes much easier to navigate. In this article, we will take a closer look at the IB grading system, what constitutes a good IB score, which subjects are the easiest and hardest, and much more. Whether you're a current IB student or just curious about the programme, this article will provide you with all the information you need to understand the IB grading system.

The IB grading system explained

The IB diploma grading system is a crucial aspect of the programme, providing a comprehensive and detailed assessment of a student's academic abilities. The IB uses a unique system of grading that awards scores on a scale of 1 to 7 in each subject, with 7 being the highest possible score. The IB grading system takes into account a variety of factors, including coursework, exams, essays, and other assignments.

In addition to subject grades, students are awarded points for completing the IB core, which consists of the Extended Essay, Theory of Knowledge, and Creativity, Action, Service (CAS) requirements. The core components can earn students up to an additional 3 points, adding to their final score out of 45.

The IB grading system uses a set of criteria to assess a student's performance in each subject. These criteria vary depending on the subject and are designed to measure a student's understanding of the material and their ability to apply critical thinking skills to real-world problems. The IB grading system also places a strong emphasis on coursework and other assessments throughout the two-year programme, rather than relying solely on final exams. This allows students to demonstrate their understanding of the material in a variety of ways and provides a more holistic view of their academic abilities.

Overall, the IB grading system is designed to be challenging and rigorous, rewarding students for their hard work and dedication. While achieving top grades in the IB programme requires a lot of effort, the programme is designed to prepare students for success in college and beyond. Universities around the world recognise the high standards of the IB programme, and many offer advanced standing or course credits to students who have earned high IB scores. Understanding the IB grading system is crucial for any student hoping to excel in the programme and achieve their academic goals.

What is the average IB grade?

According to data from the IBO, the average worldwide international baccalaureate score in 2020 was 31.34 points out of a maximum of 45. This represents a slight increase from the previous year's average score of 30.93 points. The IBO notes that the average score can vary significantly depending on factors such as location, school, and individual student performance. However, it's important to note that the IB grading system is designed to be challenging and rigorous, and achieving top grades requires a lot of hard work and dedication. According to the IBO, only 13.5% of students who took the IB in 2020 achieved a score of 40 points or above.

What is a good IB score?

A good IB score is subjective and depends on individual goals and aspirations. However, a score of 30 or above is generally considered to be a good IB score. A score of 30 points places a student in the 50th percentile, meaning they performed better than 50% of all IB candidates worldwide. Achieving a score above the average demonstrates strong academic abilities and dedication to the programme.

Achieving the top grade of 45 in the IB programme is extremely rare. In fact, in 2020, only 238 students worldwide (0.3% of all IB candidates) achieved a perfect score of 45 points. This indicates that the IB grading system is designed to be challenging and rigorous, and achieving top grades requires a lot of hard work and dedication.

It's important to note that a good IB score is just one aspect of a student's overall academic profile. Universities and employers also consider other factors such as extracurricular activities, essays, personal statements, and letters of recommendation.

Which are the easiest and hardest IB subjects?

Determining the easiest and hardest IB subjects is subjective and varies from student to student. The most popular IB subjects worldwide in 2020 were Mathematics, English, Biology, Chemistry, and Physics.

In terms of average scores, the IBO reports that the highest-scoring subjects in 2020 were English Literature and Mathematics, with average scores of 5.56 and 5.32, respectively. The lowest-scoring subjects were Mathematics Studies and Film, with average scores of 3.28 and 3.69, respectively.

It's important to note that a subject's level of difficulty can also depend on a student's individual strengths and weaknesses. For example, a student who excels in Mathematics may find it easier than a student who struggles with the subject. Although, with the right resources and help from a good IB Maths tutor, any student can achieve a top grade.

Moreover, IB subject difficulty can also vary depending on the level of the subject. The IBO offers three levels of difficulty for most subjects: Standard Level (SL), Higher Level (HL), and Studies Level (SL). HL subjects are generally considered to be the most challenging, followed by SL and then Studies.

What is a 7 in IB equivalent to?

The IB programme is graded on a scale of 1 to 7, with 7 being the highest achievable score. A score of 7 indicates that a student has demonstrated exceptional knowledge and understanding of the subject matter.

In terms of UK qualifications, a score of 7 in an IB subject is equivalent to an A* at A-Level. Similarly, in the United States, a score of 7 is equivalent to a 5 on the Advanced Placement (AP) exams.

Universities around the world recognise the high standards of the IB programme and value the skills and knowledge that students gain from it. In fact, according to a study by the Higher Education Statistics Agency in the UK, IB students are more likely to attend and succeed at top universities than their peers who have taken other qualifications.

What is a good core points score?

In addition to the six subjects, the IB diploma programme also requires students to complete three core elements: the Extended Essay, Theory of Knowledge (TOK), and Creativity, Action, and Service (CAS). These core elements are worth a maximum of 3 points each, bringing the maximum diploma score to 45.

A good core points score is subjective and depends on the student's individual goals and university aspirations. The average core points score worldwide in 2020 was 1.53, with a maximum score of 3.

While a high core points score is not necessary to obtain the IB diploma, universities often look favourably upon students who perform well in these areas. For example, the University of Cambridge states that a good core points score is "at least 2, ideally 3."

Moreover, the IBO reports that students who achieve high scores in their core elements are more likely to attend and succeed at top universities. In a study of US IB diploma holders, the IBO found that those who scored the maximum of 3 points in their core elements were more likely to attend a top 20 US university and graduate with a higher grade point average (GPA) than those who scored lower in their core elements.

How many people fail the IB?

The IB programme is undoubtedly challenging and requires a significant amount of time, effort and commitment to succeed. While the pass rate for the IB varies from year to year and from school to school, the overall pass rate for the May 2022 session was 86.11%, according to the IB website. This means that approximately 14% of students who sat the exams did not pass, which means they did not get at least 24 points or they failed some other compulsory part of the programme. This figure includes students who did not complete the programme or did not sit all of their exams.

The reasons for failure can vary from student to student, but some common factors include inadequate time management, lack of motivation, and insufficient preparation. Moreover, some students do not need the full Diploma for their future plans, so may not dedicate themselves to it. The IB programme is a rigorous academic programme that requires a high level of dedication and focus, and students who do not take their studies seriously may struggle to keep up with the workload. Additionally, the programme can be particularly challenging for students who are not comfortable with independent learning, as the IB places a strong emphasis on self-directed study and research.

IB to A-Level and AP conversion

The IB diploma programme is recognised by universities around the world and is often considered equivalent to other high school qualifications, such as A-Levels in the UK and Advanced Placement (AP) exams in the US. However, due to differences in the curricula and grading systems, direct conversion between these qualifications is not always straightforward.

In the UK, UCAS provides conversions between IB scores and A-Level grades. According to UCAS, an IB score of 38 or above is equivalent to three A-Levels at grades AAB, while an IB score of 32 is equivalent to three A-Levels at grades BBB. For information, read our article comparing the IB and A-Levels.

Similarly, the College Board, which administers the AP exams in the US, states that an IB score of 30 is equivalent to an AP grade of 3, while an IB score of 38 is equivalent to an AP grade of 5. Read more about the IB vs AP.

What IB score is needed for Harvard and Ivy League?

Harvard University requires students to maintain a minimum IB score of 40 in order to stand a good chance to get admission into Harvard University. However, it is important for IB students to score at least 38 points and above if they are aiming for an Ivy League school. Successful candidates usually have a predicted score of 38 and above to get admission in Ivy universities. US universities don’t release official cut-off scores for the IB Diploma. Yale states that "there is no minimum test score or GPA needed to be admitted," but that "most admitted students score 38-43 points on the IB Diploma."

It is also important to note that competitive universities like Harvard emphasise higher level (HL) IB subjects. Candidates should aim for a 6s and 7s for each HL subject.

What IB score is needed for Oxford and Cambridge?

The University of Oxford and the University of Cambridge have a highly selective admissions process and receive a large number of applications each year. For this reason, they often set high academic standards for applicants, including those applying with an IB diploma.

According to the University of Oxford, the typical IB offer for undergraduate courses is between 38 and 40 points out of a possible 45. This means that most successful applicants are likely to achieve at least these scores or higher. Most offers tend to also require 766 at HL, with a grade 7 in a specific subject.

However, it's important to note that offers may vary depending on the course and level of competition. For example, highly competitive courses such as medicine and law may require higher scores than the typical offer. Additionally, some colleges or departments within Oxford may have their own specific requirements or preferences.

Similarly, the University of Cambridge states that "most successful applicants achieve at least 40-42 points in the IB." This means that while a score of 40 or above is not a guarantee of admission, it is typically necessary to be competitive in the admissions process.
