The IB Diploma requirements include the following components:

OWIS - Theory of Knowledge (TOK)

Theory of Knowledge (TOK)

The Theory of Knowledge (TOK) course is compulsory for all IB Diploma students. It is a course that is designed to explore the nature of knowledge and encourages students to critically examine different ways of knowing and the methods used to acquire knowledge in various disciplines. The culmination of the TOK course involves an oral presentation and essay, where students demonstrate their ability to articulate their thoughts coherently and engage in meaningful discourse on knowledge-related issues. 

By participating in TOK through thought-provoking discussions, activities and assignments, students will not only enhance their academic capabilities but also cultivate a broader perspective and appreciation for the diverse ways in which knowledge is constructed and interpreted.

Creativity, Activity, Service (CAS)

At OWIS, the Creativity, Activity, Service (CAS) component of the IB Diploma Programme offers students a unique opportunity to engage in meaningful activities outside the classroom that foster personal growth and development. Through CAS, students have the opportunity to explore their interests, develop new skills, and make a positive impact on their communities.

Whether it’s fundraising a charity event, participating in a sports team, or exploring artistic endeavours, CAS encourages students to set personal goals, track their progress, and reflect on their experiences. By balancing creativity, physical activity, and community service, students cultivate a well-rounded and holistic approach to learning, fostering personal growth, resilience, and empathy along the way. As projects are student-initiated, it leads to high levels of engagement and fostering a sense of purpose and fulfilment. Students gain insights that prepare them for dynamic, compassionate leadership.

Extended Essay

Extended Essay

Extended Essay is one of the core components of our IB Diploma Programme that prepares students for the rigours of undergraduate research and academic writing. As a requirement for IB Diploma students, the Extended Essay entails an independent research project culminating in a 4,000-word paper. Through this in-depth research project, students have the opportunity to explore a topic of personal interest in great depth, demonstrating their ability to formulate research questions, gather and analyse data, and construct a coherent argument. 

With guidance from mentors and access to a wealth of academic resources, students embark on a journey of intellectual inquiry and discovery. As they delve into their chosen subjects such as Ethics, Human Sciences, Arts or Mathematics, students develop a deeper appreciation for scholarly inquiry and lay the foundation for future academic pursuits.

IB Diploma School Subjects

English - First language

Studies in language and literature

This subject group offers students the opportunity to engage with diverse literary forms and non-literary texts, fostering an understanding of language's role in shaping identity and culture. Students develop oral and written communication skills, analyse texts, conduct independent research, and cultivate a lifelong appreciation for literature.

Foreign Language

Individuals and Societies

This subject group enables students to explore social, economic, and physical environments. Courses like Business Management, Economics, Geography, and History foster critical analysis of concepts and theories, preparing students to evaluate societal issues and trends critically.

Students engage in practical skill-building and explore various artistic genres, fostering creativity and expression. Students opting out of this group can select alternative courses from Individuals and Societies or Sciences, ensuring a well-rounded education.

What OWIS parents and students say

Janelle R., IBDP Batch of 2021

My teachers were incredibly supportive of me and my classmates when doing IB and some really went out of their way to help us as much as they could, which I appreciated so much.

Adeliya F., IBDP Batch of 2023

At OWIS, I've learnt a lot about communication, and how it's important to be proactive, not reactive. I've also learnt that kindness and empathy are key in leadership and collaborative work.

Christina O.

I like that technology plays enough of a part within my children's studies but does not dominate basic skills towards literacy with reading, writing and presentation. There is very much a balance.
