What is an International Baccalaureate Education?

IB programmes aim to provide an education that enables students to make sense of the complexities of the world around them, as well as equip them with the skills and dispositions needed for taking responsible action for the future. They provide an education that crosses disciplinary, cultural, national, and geographical boundaries and that champions critical engagement, stimulating ideas, and meaningful relationships. The first IB programme, the Diploma Programme (DP), was established in 1968. It sought to provide a challenging yet balanced education that would facilitate geographical mobility by providing an internationally recognized university entrance qualification.

In the DP, the curriculum consists of six subject groups and the three elements of the DP core. As one of these core elements, the Theory of Knowledge (TOK) course encourages students to become more aware of their own perspectives and assumptions through an exploration of the fundamental question of how we know what we know.

The Primary Years Programme (PYP), developed in 1997, aims to transcend traditional boundaries between subject areas. Students explore six transdisciplinary themes of global significance: who we are, where we are in place and time, how we express ourselves, how the world works, how we organize ourselves, and how we share the planet.
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.
In 2018, Portledge had its first cohort of students complete the DP in our Upper School. This year, we are currently a candidate for the PYP and are implementing the IB learning attributes as we work toward school-wide consistency in this global program.
