What is IB Diploma

Simple Guide for Parents & Students

If your child is studying in an international school, you may have heard about the IB Diploma Programme — but what does it actually mean?

This guide explains it in a simple and practical way.

The International Baccalaureate (IB)

The IB (International Baccalaureate) Diploma Programme is a two-year academic program for students aged 16 to 19.

Established in 1968, the International Baccalaureate® (IB) Diploma Programme (DP) is recognized by universities around the world and, like national curricula, allows students to apply to higher education both locally and internationally.
The program was designed to provide a balanced and rigorous education, combining different subjects with skills such as writing, research, and critical thinking.
Students study a range of subjects and are assessed through a combination of final exams and coursework completed during the two years.

Beyond academics, the IB was created to support international mobility and global understanding.
It is widely used in international schools and is particularly suited for students who may study in different countries or plan to apply to universities abroad.

💡 The IB is not just about exams.
It develops independent thinking, writing, and global skills.


What Do Students Study in the IB Diploma?

The IB Diploma is different from most national systems because students do many subjects at the same time, instead of focusing on just a few.
➡️ In simple terms, over 2 years students study:

  • 6 subjects at once
  • Plus 3 additional core components

The 6 subjects

Students must choose one subject from each group, ensuring a balanced education.
Students do not study all subjects at the same depth.

  • 3–4 subjects at Higher Level (HL) → more advanced, more hours
  • 2–3 subjects at Standard Level (SL) → less depth

HL subjects require more content and deeper understanding

  • Studies in language and literature (Main language, e.g. English or Portuguese)
  • Language acquisition (A second language, ie. English, Spanish, French, etc.)
  • Individuals & Societies (Economics, Business, History, Geography)
  • Sciences (Biology, Chemistry, Physics)
  • Mathematics (Math AA or AI)
  • Arts (or optional subject) (Music, Visual Arts OR another academic subject)

The 3 core components

These core components are mandatory and studied alongside the subjects throughout the two years.

These core components are mandatory and studied alongside the subjects throughout the two years.

  • Extended Essay (EE) A 4,000-word research project on a topic chosen by the student
  • Theory of Knowledge (TOK) A course about how we think, learn, and understand knowledge
  • CAS (Creativity, Activity, Service) Activities outside the classroom (sports, arts, volunteering)

How students are graded – the IB scores

IB Score

Each subject is graded from 1 to 7.

Students can earn up to 45 points total, including bonus points from core components.

Universities often look at predicted and final IB scores for admission.

👉 Strong IB scores can open doors to top universities worldwide.

  • There is usually:
    • less independent research
    • fewer long written projects
    • less flexibility in subject choice

IB Diploma Programme

  • Students choose their subjects
  • They study a broad range (6 subjects at once)
  • They complete:
    • essays
    • research projects
    • continuous coursework
  • The focus is on:
    • understanding concepts
    • writing and analysis
    • independent thinking

Why students struggle

Why the IB Can Be Challenging

  • Heavy workload
  • High expectations
  • Combination of exams and coursework
  • Need for strong organization

Many students are not prepared for this level of independence.
