The IB Diploma Programme (IBDP)

An internationally respected pathway to university and beyond

What is the IB Diploma Programme?

The International Baccalaureate Diploma Programme (IBDP) is a two-year educational programme for students aged 16–19. Offered in over 150 countries, it is recognised globally for its academic rigour and emphasis on developing well-rounded, internationally-minded individuals.

Highly respected by the world’s leading universities, the IBDP prepares students not just for Higher Education, but for a lifetime of critical thinking, cultural understanding and engaged citizenship.

Key Features of the IBDP

Six Subject Groups: Students choose one subject from each of the following areas, with three courses taken at Standard Level and three courses at Higher Level:

  1. Studies in Language and Literature
  2. Language Acquisition
  3. Individuals and Societies
  4. Sciences
  5. Mathematics
  6. The Arts (or a second subject from another group)

In addition, all students will complete the following:

Core Components:

  • Theory of Knowledge (TOK) – A critical thinking course exploring how knowledge is constructed.
  • Extended Essay (EE) – A 4,000-word independent research paper on a topic of the student’s choice.
  • Creativity, Activity, Service (CAS) – A programme that encourages students to engage in the arts, physical activity, and community service.

IBDP vs. A-Levels: What’s the Difference?

Feature IBDP A-Levels
Subject Breadth 6 subjects across a broad range Typically 3–4 subjects, focused
Core Requirements TOK, Extended Essay, CAS None required
Assessment Style Mix of internal assessment and final exams Heavily exam-based
Global Recognition Highly regarded by universities worldwide Strong recognition, particularly in the UK
Skills Emphasised Critical thinking, research, global awareness Subject mastery and depth
Ideal For Students who enjoy challenge and variety, and are internationally minded Students with strong interest in specific subjects

Both pathways offer routes to top universities, but the IBDP is especially well-suited for students who are curious, versatile, and eager to develop both academic and personal skills.

How is the IBDP Graded?

Each of the six subjects is graded on a scale of 1 to 7, with 7 being the highest. In addition:

  • Up to 3 additional points are awarded for combined performance in TOK and the Extended Essay.

  • The maximum possible score is 45 points.

  • A score of 24 points is required to earn the full IB Diploma, provided other minimum requirements are met (e.g., completion of all core components).

IB Score Breakdown:

Component Max Points
6 Subjects (up to 7 points each) 42
TOK + Extended Essay 3
Total 45

University admissions officers around the world recognize the IBDP’s high standards and often note the strong academic preparation and independent learning skills of IB graduates.

IBDP graduates from Marymount consistently perform exceptionally well, achieving an average of around 36.3 points, well above the international average pass rate of 29 points, and we are ranked within the top 2% of IB schools worldwide.

Why Choose the IBDP?

  • Globally respected by top universities

  • Emphasises both depth and breadth of knowledge

  • Develops independent learners and critical thinkers

  • Encourages community engagement and international understanding

  • Prepares students for academic and personal success

Extended Essay

The Extended Essay is a capstone component of the IB Diploma program that offers Grade 12 students the chance to showcase their research and writing skills. With an allowance of 4,000 words at their disposal, students have the opportunity to deep dive into a topic of their choosing from one of their six IB subjects. They work closely with their supervisor throughout the process, honing their research skills, refining their arguments, and perfecting their writing.

At Marymount International School, we take pride in our commitment to multilingual education, in alignment with the IB’s mission. That’s why we’re unique in offering students the opportunity to write their Extended Essay in one of seven languages, including their native language. This gives our students the freedom to express themselves in the language they feel most comfortable in and to showcase their linguistic abilities.

For students, the Extended Essay represents a chance to stretch their research skills, explore a subject in-depth, and demonstrate their ability to think critically and independently. For universities and future employers, the Extended Essay is a testament to a student’s ability to conduct rigorous research, think critically, and communicate their ideas effectively.

In short, the Extended Essay is a vital component of the IB Diploma program, offering students the chance to show what they’re capable of and to demonstrate the skills that will serve them well in university and beyond.


Theory of Knowledge (TOK)

The Theory of Knowledge (TOK) course is a unique and intellectually stimulating experience that encourages students to explore the nature of knowledge itself. This interdisciplinary course transcends the boundaries of specific subject areas, asking students to reflect on the different types of knowledge and the various ways in which we acquire it.

At Marymount, we understand the importance of encouraging students to be aware of cultural differences and the impact of the information economy on knowledge. That’s why we’ve designed our TOK course to stimulate critical thinking and promote a deeper appreciation of the complex issues surrounding knowledge. With a diverse student population, Marymount girls benefit from the richness of active class discussions, drawing on the perspectives and experiences of their peers from around the world.

For students, the TOK course is an opportunity to broaden their horizons, reflect on their own learning experiences, and gain a deeper understanding of the nature of knowledge. They engage in thought-provoking discussions and explore the complex interplay between different subjects, cultures, and perspectives. By the end of the course, students have a better understanding of the world around them, and a greater appreciation for the diversity of thought and experience that makes our world so rich and fascinating.

In short, the Theory of Knowledge course is an essential component of the IB Diploma programme, offering students the chance to explore the nature of knowledge, engage in critical thinking, and gain a deeper appreciation for the world around them.


Creativity, Activity, and Service (CAS)

The Creativity, Activity, and Service (CAS) program at Marymount School is truly transformational for our students. As they progress through Grades 11 and 12, each girl has the opportunity to develop her leadership, artistic, physical, and community skills through a series of challenging and meaningful experiences.

At its core, the CAS program is designed to enhance the personal and social development of our students, encouraging them to explore their passions, push their boundaries, and become well-rounded individuals. Through the compilation of a portfolio that demonstrates their creative thinking, physical activity, and voluntary service work, our girls are given the opportunity to reflect on their growth and see the tangible impact of their efforts.

The CAS program aligns perfectly with the RSHM Mission of educating the whole person, providing each of our students with the tools they need to become confident, empathetic, and engaged members of their communities. Whether they are participating in a leadership workshop, taking up a new sport, or volunteering in their local community, our students are given the chance to challenge themselves, to develop their skills, and to share their gifts with others.

The results of the CAS program speak for themselves. Our students leave Marymount as confident, well-rounded individuals, with a sense of purpose and a commitment to making a positive impact in the world. Whether they are pursuing higher education, entering the workforce, or pursuing their passions, our graduates are prepared for success, with the leadership, artistic, physical, and community skills they need to thrive.

In short, the CAS program is an essential part of the Marymount experience, offering our students the opportunity to develop their personal and social skills, to challenge themselves, and to make a positive impact in the world.
