About IBO


The International Baccalaureate Organization was founded in Geneva, Switzerland in 1968 as a non-profit educational foundation.


The International Baccalaureate aims to develop inquiring, knowledgeable and caring young people who help to create a better and more peaceful world through intercultural understanding and respect. To this end, the IB works with schools, governments, and international organizations to develop challenging programmes of international education and rigorous assessment. These programmes encourage students across the world to become active, compassionate and lifelong learners who understand that other people, with their differences, can also be right. 

Main activities

The IB works in four areas:

  1. Development of curriculum
  2. Assessment of students
  3. Training and professional development of teacher
  4. Authorization and evaluation of schools


On 18 March 2019, there were 6,521 programmes being offered worldwide, across 5,000 schools in 153 countries.

IB World Schools

The IB does not own or manage any schools. Instead, IB works with schools around the world (both state and privately funded) that share our commitment to international education.

Schools that have been authorized by IB to offer one or more of our programmes are known as "IB World Schools". These schools:

  1. share the mission and commitment of the IB to quality international education.
  2. play an active and supporting role in the worldwide community of IB schools.
  3. share their knowledge and experience in the development of the IB programmes.
  4. are committed to the professional development of teachers.

Authorization to become an IB World School is an intensive process that typically takes two or more years and includes site visits by an IB team.


The IB offers four programmes for students aged 3 to 19. IB World Schools can offer the programmes individually or as a continuum.

  1. The Primary Years Programme (PYP) for students aged 3-12 started
    in 1997 and is now offered by 1,472 IB World Schools in 109 countries. 
  2. The Middle Years Programme (MYP) for students aged 11-16 started in
    1994 and is now offered by 1,356 IB World Schools in 108 countries. 
  3. The Diploma Programme (DP) for students aged 16 to 19 started in 1968 with first examinations in 1970 and is now offered by 2,627 IB World Schools in 140 countries with over 500,000 graduates since 1970. It is a challenging two-year curriculum that is widely recognised by leading universities throughout the world.
  4. The Career-related Certificate (IBCC) for students aged 16 to 19 is a new programme within the IB.
