Diploma Program





Our Post-16 Programme is for Grades 11 and 12 (ages 16+). It gives students the opportunity to specialize in specific areas of interest, preparing them for university and college entrance as well as future careers. Students learn how to do academic research, in the process becoming self-aware critical thinkers and time managers.

Our goal is to develop empathic, internationally minded learners that contribute positively to society.

ISD students achieve above world average results. Graduates consistently place in major universities in North America, Australia, Asia, the UK, and Europe.


The IB DP (International Baccalaureate Diploma Programme) is the foundation of study in the Post-16 Programme. The DP is a holistic model of education, academically broad and balanced. It focuses on disciplinary, interdisciplinary, and intercultural understanding.


Classes are held in the Secondary building, which boasts a towering ceiling, natural light, dedicated art and design spaces, and a central open area.

Paths of Study

There are two paths of study in the Post-16 Programme. Each leads to a distinct outcome. With guidance from our college counselors and the DP Coordinator, students choose the path best suited to their goals and abilities.

Path 1 — ISD High School Diploma and IB Courses

Students study a combination of IB Diploma Programme subjects leading to the ISD High School Diploma with the potential to qualify for certificates in some IB Diploma courses. Students are not required to study TOK (Theory of Knowledge) or complete the Extended Essay, but successful participation in CAS (Creativity, Activity, Service) is compulsory.

Post-secondary options include:

- United States: 4-year universities and colleges and 2/3-Year Community Colleges

- Bangladesh: universities and colleges

- Canada: 2/3-year colleges

- UK, Australia, and Asia: Foundation Programmes as pathways to future university study

Path 2 — ISD High School Diploma and IB Diploma

The most demanding path in terms of commitment and application. Students study a combination of IB Diploma Programme subjects with the potential to qualify for the full IB Diploma and the ISD High School Diploma. Students write a 4,000-word Extended Essay and complete courses in TOK (Theory of Knowledge) and CAS (Creativity, Activity, Service).

Post-secondary options include:

- 4-year undergraduate programmes

- United States and Canada: 4-year undergraduate degree programmes

- UK, Netherlands, Spain, Switzerland, Australia: 3-year undergraduate degree programmes

- Asia (incl. China, Hong Kong, Japan, Singapore, Thailand): 3/4-year undergraduate degree programmes


Common Core Subjects

Three components form the core of the IB Diploma Programme and are mandatory subjects for all DP students. For ISD High School Diploma students, only CAS is compulsory.

CAS (Creativity, Activity, Service)

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.

TOK (Theory of Knowledge)

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.

Extended Essay

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.
