IB Core Components vs. Internal Assessment (IA): What’s the Difference?
The International Baccalaureate (IB) Diploma Programme is known for its rigorous academic structure and emphasis on holistic education. Two key elements of the IB are the Core Components (TOK, EE, and CAS) and the Internal Assessment (IA). While both are essential for earning the IB Diploma, they serve different purposes and have distinct requirements. Doing a “Components vs Internal Assessment”, let’s break down the differences to help you understand their roles in your IB journey.
What Are the IB Core Components?
The IB Core Components are three mandatory elements that go beyond traditional academic subjects. They are designed to develop critical thinking, research skills, and personal growth. The core components include:
- Theory of Knowledge (TOK): A course that explores the nature of knowledge and how we know what we claim to know.
- Extended Essay (EE): A 4,000-word independent research paper on a topic of your choice.
- Creativity, Activity, Service (CAS): A program that encourages students to engage in creative, physical, and service-oriented activities.
Key Features of the Core Components:
- They are interdisciplinary and focus on skills beyond subject-specific knowledge.
- TOK and the EE contribute up to 3 bonus points to your overall IB Diploma score.
- CAS is not graded but is a mandatory requirement for the diploma.
What Is the Internal Assessment (IA)?
The Internal Assessment (IA) is a subject-specific assignment or project that is internally assessed by your teachers and externally moderated by the IB. Each IB subject has its own IA, which evaluates your ability to apply knowledge and skills learned in class.
Key Features of the IA:
- The format varies by subject. For example:
- In Science, it’s typically a lab report or investigation.
- In History, it could be a historical investigation.
- In Math, it might be a written exploration of a mathematical topic.
- The IA usually counts for 20–30% of your final grade in that subject.
- It focuses on subject-specific skills, such as analysis, experimentation, or problem-solving.
Key Differences Between IB Core Components and IA
| Feature | IB Core Components | Internal Assessment (IA) |
|---|---|---|
| Purpose | Develops critical thinking, research, and personal growth. | Assesses subject-specific knowledge and skills. |
| Includes | TOK, Extended Essay (EE), and CAS. | Subject-specific coursework (e.g., Math IA, Science IA). |
| Grading | TOK and EE are graded; CAS is compulsory but ungraded. | Counts for 20–30% of the final subject grade. |
| Assessment | TOK and EE are externally assessed; CAS is self-reported. | Internally assessed by teachers, externally moderated by IB examiners. |
| Impact on IB Score | Can add up to 3 bonus points to the IB Diploma score. | Directly affects the final grade in each subject. |
| Type of Work | Research-based essays, critical thinking tasks, and extracurricular activities. | Investigations, experiments, essays, oral assessments. |
Why Are Both Important?
- The Core Components ensure you develop skills like critical thinking, research, and community engagement, which are essential for university and beyond.
- The IA allows you to demonstrate your understanding and application of subject-specific knowledge, contributing significantly to your final grades.
How to Excel in Both
- For Core Components:
- Start early on your TOK essay and EE to allow time for research and revisions.
- Choose CAS activities that align with your interests and passions.
- For IA:
- Follow your teacher’s guidelines carefully.
- Practice regularly and seek feedback to improve your work.
