Diploma Programme

The International Baccalaureate (IB) Diploma Programme (DP) is a rigorous, two-year educational program for students aged 16 to 19. It is designed to provide a challenging, internationally-focused curriculum that encourages students to develop critical thinking, research, and communication skills. The DP includes six subject groups and three core components: Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS). These elements work together to promote a balanced education, fostering both academic and personal growth. The DP is highly regarded by universities worldwide, offering students excellent preparation for higher education and global citizenship.

How Many Grades Do You Need in IBDP?

In the International Baccalaureate Diploma Programme (IBDP), students need to achieve a total of at least 24 points out of a possible 45 to earn the diploma. Here’s a breakdown:

  1. Subject Scores: Students take six subjects, each graded on a scale from 1 to 7. This gives a maximum of 42 points (6 subjects x 7 points each).
  2. Core Components: The three core components—Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS)—collectively contribute up to 3 additional points based on the grades achieved in TOK and the EE, for a total maximum score of 45 points.

Core Components

The three core components—Theory of Knowledge (TOK), the Extended Essay (EE), and Creativity, Activity, Service (CAS)—collectively contribute up to 3 additional points. Now let's understand what are these three components.

Theory of Knowledge (TOK):

  • Overview: TOK is a unique course that challenges students to reflect on the nature of knowledge and how we know what we claim to know.
  • Objectives: It encourages critical thinking about knowledge itself and helps students make connections between academic disciplines.
  • Assessment: Students complete a TOK essay and an exhibition. The essay is externally assessed, while the exhibition is internally assessed and externally moderated.

Extended Essay (EE):

  • Overview: The EE is an independent, self-directed piece of research, culminating in a 4,000-word paper.
  • Objectives: It provides students with the opportunity to investigate a topic of interest in-depth, develop research and writing skills, and engage in a formal process of academic inquiry.
  • Assessment: The essay is assessed by external examiners. Students are also required to complete a reflection process, which is documented in three formal reflection sessions with their supervisor.

Creativity, Activity, Service (CAS):

  • Overview: CAS involves students in a range of activities alongside their academic studies throughout the IBDP. It aims to enhance personal and interpersonal development through experiential learning.
  • Objectives: The three strands of CAS are:
  1. Creativity: Exploring and extending ideas leading to an original or interpretive product or performance.
  2. Activity: Physical exertion contributing to a healthy lifestyle.
  3. Service: Collaborative and reciprocal engagement with the community in response to an authentic need.
  • Assessment: While CAS is not formally assessed with grades, students must document their activities and reflections through a portfolio and demonstrate they have met the seven CAS learning outcomes. This portfolio is reviewed by the CAS coordinator and school.
