About the International Baccalaureate

The International Baccalaureate is a non-profit foundation offering four high-quality and challenging educational programs for students aged 3 to 19 throughout the world.  Founded in 1968, the IB has grown and is now established in over 5,700 schools in 159 countries worldwide.  

Authorization to become an IB World school is an intensive process that typically takes two or more years.  IB World Schools are regularly evaluated by IB once they have been authorized to ensure they maintain the high educational and curricular standards set by the International Baccalaureate.  IB teachers are first required to attend training provided by the IB to become an IB teacher and then attend ongoing training to ensure that they are up to date on the most current IB curriculum.

The International Baccalaureate Mission:

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 organization works with schools, governments and international organizations 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.
