What Is the IB DP Curriculum?

The IB Diploma Programme (IB DP) is a rigorous, internationally recognized two-year curriculum offered by the International Baccalaureate (IB) for students aged 16–19. With its emphasis on breadth, depth, research, critical thinking, and global mindedness, the IB DP is designed to prepare students for higher education and life beyond school.

IB DP Subjects Groups

The IB DP curriculum is a balanced, challenging programme that combines six subject groups with a three-part DP core.

  1. Studies in Language & Literature (Language A)
  2. Language Acquisition (Language B / ab initio)
  3. Individuals & Societies
  4. Sciences
  5. Mathematics
  6. The Arts (or an elective from another group)

DP Core: Comprises three central, compulsory components:

  1. Theory of Knowledge (TOK) - critical reflection on the nature of knowledge.
  2. Extended Essay (EE) - an independent, self-directed research project of up to 4,000 words.
  3. Creativity, Activity, Service (CAS) - student involvement in creative, physical, and service work.

Students typically take three (or sometimes four) Higher Level (HL) courses and the rest at Standard Level (SL). HL courses involve greater depth, more instructional hours, and increased expectations.

This structure ensures both breadth (across disciplines) and depth (in areas of interest), while integrating critical thinking, inter-disciplinary learning, and independent inquiry.

IB DP Curriculum Structure

Component Description
Subject Groups (6) Students choose one subject from each group (or equivalent). They may substitute a second subject from certain groups instead of the Arts.
Levels HL (higher) and SL (standard) levels; differences in content coverage, assessment complexity, and teaching time.
Core (TOK, EE, CAS) Designed to tie together subject learning, research skills, ethics, creativity, and community engagement.
Internal & External Assessment Each subject includes internal assessments (e.g., investigations, projects, oral work) and external assessments (final exams, extended responses) to gauge student mastery.
Subject Updates & Pilots The IB periodically updates subject syllabi and may pilot new subjects or school-based syllabuses (SBS) to stay current.

Note:

SBS (school-based syllabus) is allowed only in certain subject groups (Individuals & Societies, Sciences, Arts) and must be authorized by IB.

Beyond Subjects, the IB DP Curriculum Emphasizes

The IB DP is more than just subject content. It places strong emphasis on:

  1. Interdisciplinarity
  2. TOK encourages students to reflect on how different disciplines relate—and to question assumptions about how knowledge is constructed.

  3. Inquiry and Research
  4. The Extended Essay demands independent inquiry, critical thinking, and academic writing—preparing students for university research tasks.

  5. International Mindedness
  6. The IB mission is woven through the DP: cultivating open-minded, culturally aware learners who can operate in a global environment.

  7. Learner Profile & Approaches to Learning (ATL)
  8. The DP integrates the IB Learner Profile (e.g., inquirers, reflective, communicators) and ATL skills (thinking, communication, social, self-management, research) into teaching, assessment, and reflections.

  9. Community, Service & Ethics
  10. Through CAS, students engage with local communities, reflect on ethical issues, and develop a sense of civic responsibility.

These aspects ensure the IB DP shapes not just academic competence but a more holistic student profile.

IB DP Assessment Types

IB DP assessment aims to ensure fairness, reliability, and consistency across the globe, making it one of the most respected academic evaluation systems in international education.

Types of Assessment in the IB DP

The IB DP uses a combination of internal and external assessments to provide a balanced measure of student achievement.

  1. Internal Assessments (IA)
    • Conducted and initially marked by teachers at the school level.
    • Examples include oral work in languages, science practical investigations, mathematical explorations, and artistic performances.
    • Each internal assessment is moderated externally by the IB to maintain consistency and fairness across all IB World Schools.
  2. Purpose:

    To assess the skills that cannot be effectively evaluated in written exams, such as research, analysis, creativity, and presentation.

  3. External Assessments
    • Conducted and graded by international IB examiners.
    • These typically include written examinations, extended essays, and certain coursework components.
    • Exams are taken at the end of the two-year programme, and all scripts are marked according to detailed global rubrics.
  4. Purpose:

    To measure conceptual understanding, critical thinking, problem-solving, and clarity of communication under standardized conditions.

The IB Grading System

Each subject in the IB DP is graded on a scale of 1 to 7, where:

  • 7 = Excellent performance.
  • 1 = Very poor performance

In addition to the six subjects, students can earn up to 3 extra points based on combined performance in:

  • Theory of Knowledge (TOK).
  • Extended Essay (EE)

This brings the maximum achievable score in the IB DP to 45 points (6 subjects × 7 points + 3 core points).

Frequently asked Questions

Who can apply for the IB Diploma Programme?

Any student aged 16–19 who has completed their secondary or middle years education (such as MYP, IGCSE, ICSE, or CBSE Grade 10) can apply. Some schools may conduct placement tests or interviews to ensure students can manage the programme’s academic demands.

Is the IB DP harder than other boards like CBSE, A Levels, or AP?

The IB DP is known for its depth, breadth, and continuous assessment, which can make it more challenging.

However, it is also flexible and skills-focused, encouraging critical thinking and independence — qualities that universities value highly.

It’s not necessarily “harder,” but it’s different in structure and philosophy.

How do universities view the IB Diploma?

Universities worldwide — including Ivy League, Oxbridge, and top Asian and European institutions — highly value the IB Diploma.

It demonstrates readiness for college-level research, critical thinking, and global engagement.

Some universities even offer credits or course exemptions for high DP scores.

How is IB assessment different from traditional exams?

IB assessment blends internal assessments (IA) and external exams.

It values conceptual understanding over rote memorization, evaluating skills like reasoning, research, and application.

Final grades are standardized worldwide by IB examiners to ensure fairness.
