Service as action requires students to contribute their time and skills by taking action to serve the community. The MYP encourages students to meaningfully engage with service as action and reflect on their experience. The school offers a variety of options to engage with service which broadly fall into the following categories:

• Service and action through the curriculum via the units taught
• Individual or group service projects initiated and run by students
• Whole school service days

The culminating experience for students in the MYP is the Personal Project, a self-directed individual project lasting approximately 8 months, in the final year of the MYP.
The Project is driven by each student's passions and interests whether it be coding a website, shooting a documentary film on social injustices or planning a cookery class. Students establish a challenging goal which they work towards with the guidance of an individually assigned  teacher supervisor. At the end of the project, students showcase their final products and outcomes and their learning journey through an exhibition that is open to the wider community. All personal projects are externally moderated by the IB and a certificate is issued for the completion of the project.

What is the nature of knowledge? How do we know that a given claim or judgment is true or well grounded? Questions comprise almost the whole of TOK. Students and their teachers contemplate the diverse ways of knowing, areas of knowledge, and the role that knowledge plays in our world. Students learn about the strengths and weaknesses of knowledge claims made in each of their subject areas. TOK oral presentations and essays are externally assessed against a range of criteria.

The heart of the DP, the CAS programme aims to educate the whole student. There is life beyond the books! Although not graded, CAS requires students to prove they have achieved eight learning outcomes in their reflection journals, a sample of which are submitted to the IB. Students gain awareness of themselves and others by committing to projects with authentic needs within and beyond the ISD community. CAS projects have included establishing a football league for local children, constructing water tanks and shelters, teaching music, painting school murals, and organizing competitions. By doing and reflecting on these projects, students develop pivotal life skills and well-roundedness, traits valued by university admissions officers.

A self-directed mini-thesis of 4,000 words, the Extended Essay prepares students for future university study. Graduates often remember the experience as one of their most rewarding of the IB Diploma journey. Students write on a topic of interest that relates to a DP subject area, frequently focusing on their career ambitions. They learn to work independently, communicate ideas logically in a written form, and effectively manage their time over the 10 months of the inquiry. Essays are externally assessed against a range of criteria.
