While achieving at least 24 points is one of the requirements for earning the IB diploma, it is far from the only condition. Every year, students who achieve 24 points or more are still not awarded the IB Diploma because they fail to meet one or more additional requirements established by the International Baccalaureate. Understanding these failing conditions is important because it allows students to identify potential risks early and avoid unpleasant surprises when final results are released. In this guide, we will outline the most common failing conditions that prevent students from obtaining their IB diploma.
IB Diploma Failing Conditions
Scoring Fewer Than 24 Total Points
The most well-known failing condition is earning fewer than 24 total points out of a possible 45. The final IB score consists of points earned across six academic subjects, plus up to three bonus points awarded through Theory of Knowledge (TOK) and the Extended Essay (EE). Students who score 23 points or below will not be awarded the diploma, regardless of their performance in individual subjects. This means that even if a student has a 7 in one subject, but still does not meet the overall point total requirement of 24, they will not be awarded the IB diploma. Although 24 points is the minimum passing threshold, students must also satisfy several additional requirements to receive the diploma. These requirements are discussed below.
Failing to Complete CAS Requirements
Unlike academic subjects, Creativity, Activity, and Service (CAS) is not assigned a numerical grade. However, successful completion of CAS is mandatory for the award of the IB Diploma. Students who fail to complete their CAS experiences, reflections, learning outcomes, or required interviews with their CAS coordinator will not receive the diploma, even if they achieve excellent academic results. This makes CAS one of the most important non-exam components of the programme.
Receiving an E or N in TOK or the Extended Essay
Theory of Knowledge and the Extended Essay are both essential components of the IB Diploma core. Students who receive a grade of E in either TOK or the EE automatically fail to qualify for the diploma. Similarly, receiving an "N" grade, which typically indicates that a required component was not submitted, also results in the diploma not being awarded. Because TOK and the EE contribute bonus points toward the final score, many students underestimate their importance, but failing either component has serious consequences. Students not only lose the extra 3 core points from TOK/EE, but are at risk of losing the entire IB diploma as well.
Receiving a Grade 1 in Any Subject
A grade of 1 is the lowest possible score that can be awarded in an IB subject. Receiving a grade of 1 in any Higher Level (HL) or Standard Level (SL) course automatically disqualifies a student from receiving the diploma. This means that even students with high overall scores can fail the diploma if they perform extremely poorly in a single subject.
Receiving Too Many Grade 2s
The IB allows students to receive some lower grades while still earning the diploma. However, students who receive a grade of 2 in three or more subjects will not be awarded the diploma. This rule applies regardless of whether the grades are earned in HL or SL courses. As a result, students should pay particular attention to subjects in which they are consistently performing near the lower grade boundaries.
Receiving Too Many Grades of 3 or Below
Students may also fail the diploma if they receive four or more grades of 3 or below across their six subjects. This condition includes all grades of 1, 2, and 3 combined. For example, a student receiving four grades of 3, despite achieving more than 24 total points, would still fail to receive the diploma. This requirement emphasizes the IB's expectation that students demonstrate competency across their entire programme of study.
Not Meeting the Higher Level Requirement
Students taking the standard IB Diploma with three Higher Level subjects must earn a combined total of at least 12 points across their HL courses. Students who register for four HL subjects have their three highest HL scores counted toward this requirement. Failing to achieve the minimum HL point total will result in the diploma not being awarded, even if the student's overall score exceeds 24 points.
Not Meeting the Standard Level Requirement
Similarly, students must achieve a combined total of at least 9 points across their Standard Level subjects. For students taking only two SL subjects, the minimum requirement is 5 points. Although this condition is less commonly discussed than the HL requirement, it remains an important criterion for earning the diploma.
Tips on Avoiding Failure
Although the failing conditions established by the International Baccalaureate may seem intimidating, the reality is that most students who fail the diploma do so because of preventable mistakes rather than a lack of academic ability. By staying organized, seeking support early, and maintaining consistent habits throughout the programme, students can significantly improve their chances of success. Here are some tips to avoid failing the IB:
- Track Your Overall Point Total Regularly – Many students focus only on individual subjects and lose sight of their overall diploma score. Calculate your projected total points throughout DP1 and DP2 to ensure that you remain on track to achieve the minimum 24-point requirement.
- Prioritize Passing Every Subject – Even if you excel in certain courses, avoid neglecting subjects that you find difficult. Receiving a grade of 1 automatically prevents the award of the diploma, regardless of your overall score or performance elsewhere.
- Monitor Low Grades Early – If you begin receiving grades of 2 or 3 in multiple subjects, address the problem immediately. Meet with your teachers, seek tutoring support, and develop a targeted plan for improvement before final examinations approach.

- Stay Organized with Internal Deadlines – Create a calendar that includes all internal assessments, TOK and EE deadlines, CAS requirements, and major assignments. Missing deadlines often creates unnecessary stress that can negatively affect performance across multiple subjects.
- Complete CAS Consistently – Avoid treating CAS as unimportant or easy to finish quickly. Regularly update your reflections, document experiences thoroughly, and maintain communication with your CAS coordinator throughout both years of the programme.
- Start Your Extended Essay Early – The Extended Essay frequently becomes a major source of stress during DP2. Beginning research and drafting during DP1 or the summer break can prevent rushed work and reduce the likelihood of receiving a poor grade.
- Take Theory of Knowledge Seriously – Because TOK contributes relatively few points, students sometimes underestimate its importance. Remember that receiving an E in TOK automatically prevents the award of the diploma, regardless of your academic performance.
- Pay Special Attention to Higher Level Subjects – Since students must meet minimum Higher Level point requirements, consistently monitor your performance in HL courses. Seek assistance immediately if your predicted grades begin to decline.
- Ask for Help Before Problems Escalate – Teachers, coordinators, counsellors, and classmates can all provide valuable support. Addressing academic challenges early is significantly easier than attempting to recover during the final months of DP2.
- Maintain a Healthy Balance – Academic success in the IB is closely linked to physical and mental well-being. Prioritize sleep, exercise, social activities, and personal interests to avoid burnout and maintain consistent performance throughout the programme.
