Failing an IB Higher Level (HL) subject can feel like a devastating setback—but it doesn’t automatically mean you’ll lose your diploma. The International Baccalaureate Diploma Programme (IBDP) has specific rules and combinations that determine whether a failed HL subject affects your diploma status.
In this article, we’ll break down what happens if you fail an HL subject, what the IB rules say, and how to recover or retake effectively.
What Counts as “Failing” an HL Subject?
IB HL subjects are graded on a 1 to 7 scale, with 4 generally considered a passing mark. A score of 3 or below is typically seen as a fail.
However, your diploma eligibility is determined by more than a single subject. It depends on how all your points add up.
Can You Still Get the Diploma If You Fail One HL Subject?
Yes—in some cases, you can still earn the diploma, even if you fail one HL subject.
According to IB Diploma Requirements (Updated 2025):
You must meet the following:
- A total of at least 24 points
- At least 12 points from your three HL subjects
- At least 9 points from your three SL subjects
- No score below a 3 in HL
- No more than one subject with a score of 2 (HL or SL)
- Meet core component requirements (TOK, EE, CAS)
So, if you score a 3 in one HL subject, but your other HLs total 12 points or more, you’re still eligible. But scoring 2 or lower in any HL subject is automatically disqualifying.

How Do HL Scores Affect University Admissions?
Most universities pay close attention to HL subjects, especially in competitive programs like:
- Medicine
- Engineering
- Law
- Business or Economics
If you fail or underperform in a required HL subject (e.g., HL Chemistry for medicine), it can impact:
- Conditional offers
- Scholarships
- Eligibility for reapplication
What Are Your Options If You Fail an HL Subject?
1. Retake the HL Subject in the Next Session
- You can retake up to three subjects in a future session (May or November)
- You’ll need to register through your school or an IB retake center
- You can also improve IA scores if allowed
2. Apply to Universities That Consider Final Scores
- Some universities accept post-results applications
- You may also qualify through Clearing or foundation programs
3. Explore Non-Diploma Pathways

- Many institutions recognize course-specific performance

FAQs About Failing IB HL Subjects
Q1: Can I pass the diploma with two HL scores of 3 and one 4?
Yes, if the total is 10+ and your SLs and core components compensate to reach 24+ points.
Q2: Can I switch HL subjects during a retake?
Only if your school or exam center allows it—and you’ve completed sufficient coursework (IA, syllabus coverage).
Q3: Can I appeal my score?
Yes. You can request a remark (EUR – Enquiry Upon Results) through your IB coordinator.
Q4: Do HL retakes hurt university chances?
Not necessarily. If you improve your score, most universities welcome it—especially if you explain your circumstances.
