IN BRIEF

An IB school is a school authorized by the International Baccalaureate to teach one or more of its programmes. IB schools share an inquiry-based approach, a common learner profile and a focus on international-mindedness, which is why many internationally mobile families look for them.

 

If you are moving to a new country or comparing schools for the first time, the letters “IB” appear quickly. Many families hear that IB schools are rigorous and internationally recognized, but fewer have a clear picture of what the International Baccalaureate actually is, or what it changes in a student’s day-to-day learning.

This guide explains what an IB school is, how the programmes are structured and why international families often choose the IB.

 

The IB is less about what students memorize and more about how they learn to ask, connect and reflect.

 

What is an IB school?

The International Baccalaureate (IB) is a non-profit educational foundation established in Geneva in 1968. An IB school — officially, an IB World School — is a school that has been authorized by the IB to offer one or more of its programmes.

Authorization is not a one-time label. Schools go through an application process and are evaluated periodically to confirm that they continue to meet IB standards. That is the short answer to “what is an IB school”: a school that teaches an IB programme under external authorization and shares a common educational philosophy with thousands of schools in more than 150 countries.

IB curriculum explained: the four programmes

The IB offers four programmes. A school may teach one of them or several, forming a continuum from early years to pre-university:

Programme Ages Focus
Primary Years Programme (PYP) 3–12 Transdisciplinary inquiry: learning to ask questions and connect subjects.
Middle Years Programme (MYP) 11–16 Connecting subjects to real-world contexts and developing approaches to learning.
Diploma Programme (DP) 16–19 A two-year pre-university programme with six subject groups and a core: Theory of Knowledge, the Extended Essay and CAS (Creativity, Activity, Service).
Career-related Programme (CP) 16–19 IB courses combined with career-related studies.

 

In Spanish-speaking countries, these programmes are known as PEP (PYP), PAI (MYP) and PD (DP) — names that families in Mexico will often see on school websites.

What makes the IB approach different?

  • Inquiry: students investigate questions instead of only receiving answers.
  • Concepts, not isolated facts: learning is organized around big ideas that transfer across subjects.
  • International-mindedness: students consider perspectives from other cultures and contexts.
  • The learner profile: ten attributes — inquirers, knowledgeable, thinkers, communicators, principled, open-minded, caring, risk-takers, balanced and reflective — shape the whole school experience.
  • Assessment for learning: clear criteria, feedback and self-reflection help students understand how to improve.

IB education for international families: why they choose it

For families who move between countries, IB education offers something especially valuable: continuity.

  • A shared framework: a student moving from one IB school to another finds familiar structures, vocabulary and expectations.
  • International recognition: the IB Diploma is recognized by universities around the world.
  • Language and culture: the programmes encourage learning additional languages and valuing one’s own culture alongside others.
  • The whole student: wellbeing, service and personal growth are part of the programme, not an extra.

 

For a family that moves, the IB can be a common thread between one country and the next.

 

International Baccalaureate benefits — and what to consider

International Baccalaureate benefits often include strong research and writing skills, comfort with complex questions and an international outlook. At the same time, the IB is demanding: it asks students to manage their time, work independently and reflect on their own learning. Families should ask how a school supports students through that process.

Why choose an IB school? Questions to ask on a visit

  • How long has the school been teaching them?
  • How are teachers trained in the IB approach?
  • How does the school support students learning in a second language?
  • How is wellbeing supported alongside academic demands?
