How Does the IB Diploma Work? A Clear Breakdown for Students and Parents

The IB Core Components Explained

1. Extended Essay (EE)

• A 4,000-word independent research paper
• Done on any IB subject
• Assesses research, analysis, and writing skills

2. Theory of Knowledge (TOK)

• A course exploring how we know what we know
• Includes a TOK exhibition and essay
• Encourages critical thinking about knowledge sources

3. Creativity, Activity, Service (CAS)

• Involves community service, personal projects, and extracurriculars
• Non-graded, but mandatory for diploma award
• Aims to develop students beyond academics

How Is the IB Diploma Graded?

Each subject is graded on a scale of 1 to 7. That gives a maximum of 42 points for your six subjects.

The core components (TOK and EE) contribute up to 3 bonus points based on a performance matrix.

Scoring Example:

• Subject Grades: 6 + 6 + 5 + 5 + 6 + 6 = 34
• TOK/EE: 2 bonus points
• Total Score: 36/45

You need at least 24 points to pass, but there are specific conditions.

What Are the Pass Requirements for the IB Diploma?

To earn the diploma, students must:

• Score at least 24 points total
• Complete all core components (EE, TOK, CAS)
• Receive no more than:
  • 3 points at Level 3 or below in HL subjects
  • 7 points at Level 2 or below in SL subjects
• Not get a grade 1 in any subject

Even if you reach 24 points, you can still fail the diploma if certain conditions aren't met.

• Include essays, lab reports, oral presentations, and projects

• The largest contributor to subject grades
