Failing either the Theory of Knowledge (TOK) essay or Creativity, Activity, Service (CAS) component of the IB Diploma Programme can have serious consequences. While the IB is designed to support students in meeting requirements, it is crucial to understand what’s at stake—and how to avoid or address failure.
Failing the TOK Essay
- Failing the TOK essay alone doesn’t automatically mean you fail the diploma. Your final TOK grade is based on both the essay and the exhibition (or presentation in older syllabi).
- If you receive an E grade overall in TOK (from combining essay and exhibition scores), you fail the core requirement and cannot be awarded the IB Diploma, no matter how well you do in your subjects.
- To actually “fail” the essay, it would need to be completely off-topic, not address the prescribed title, or be incoherent. Weak essays typically earn low marks but not outright failure.
- A strong performance on the exhibition can balance a weak essay and help you avoid an E grade overall.
- If you fail TOK, your school may allow a resubmission or require you to retake the course, depending on IB and school policies.
Failing CAS
- CAS is a mandatory core component. Failure to complete CAS satisfactorily means you do not earn the IB Diploma, even if you pass all subjects and other core components.
- CAS isn’t graded, but your school must confirm that you met the learning outcomes. If you fall short, you’ll be required to complete missing work (such as reflections, documentation, or hours) before your diploma is awarded.
What Happens If You Fail Either?
- No diploma is awarded until all core components (TOK, CAS, and the Extended Essay) and subject requirements are satisfied.
- Most schools offer support and opportunities to address issues, whether that means resubmitting work, completing missing CAS activities, or providing extra guidance.
- Extreme cases like plagiarism or non-submission may limit your options for recovery.
How to Avoid Failing TOK or CAS
- Follow the IB criteria carefully. Ensure your TOK essay addresses the prescribed title and demonstrates critical thinking.
- Stay on top of CAS documentation and reflections. Don’t leave your CAS project to the last minute.
- Seek feedback early from your TOK teacher or CAS coordinator if you’re struggling.
- Plan ahead to balance core requirements with subject work.
Summary
- Failing the TOK essay alone doesn’t fail your diploma, but an overall E grade in TOK does.
- Failing CAS means no diploma until requirements are fulfilled.
- Schools typically provide ways to address failures—through resubmission or completing additional work.
- Proactive communication and planning are key to avoiding serious consequences.
