The International Baccalaureate: 16 - 18 Years 

IB Co-ordinator: Ms Katharina Stillitano

IBO Mission Statement

The International Baccalaureate Organisation 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 IBO works with schools, governments and international organisations to develop challenging programs of international education and rigorous assessment. 

These programs encourage students across the world to become active, compassionate and lifelong learners who understand that other people, with their differences, can also be right.

IB and Montessori

The International Baccalaureate (IB) Diploma is a two year program for students aged between 16 and 19 years.  It is a comprehensive and demanding course for students seeking tertiary entrance.

The IB is considered to be uniquely compatible with a Montessori education.  It is a broad but balanced course, global in outlook, which emphasises the same 'learning how to learn' approach as Montessori, and focuses on the development of the whole person.

The focus on the shared nature of humanity, embedded in the Montessori approach from 3 years of age, reaches full consciousness as the students dedicate both thought and work to realising their own part in the "web" of humanity.  Contribution through service to others gives expression to this realisation.

The IB program, with its three subjects at a higher level and three at standard level, requires all participants to engage in the study of Languages, Sciences, Mathematics and Humanities until the completion of their secondary schooling.

Three further requirements contribute to the unique nature of the Diploma:

  • the compulsory participation in artistic and sporting activities and community service (CAS - Creativity, Action, Service)

  • an extended essay of some 4000 words in one of the subjects of the IB curriculum

  • and a course on Theory of Knowledge

The International Baccalaureate is accepted by most universities worldwide, all universities in Australia and all universities in Western Australia.  Hundreds of schools in the world are IB schools. 

The Montessori School was the first school in Western Australia to offer the IB.  It was also the first Montessori school worldwide to be a member school.
