A Choice That Opens Doors

IB Diploma Programme

An alternate pathway to academic excellence and global opportunity

The International Baccalaureate (IB) Diploma Programme provides students with a globally recognised, academically challenging course designed to develop inquiring, knowledgeable, and caring graduates. At St Peter's Girls, we know students thrive when they're challenged and encouraged to push themselves further.

We’re proud to offer the IB Program as an exciting option that gives our girls greater choice, inspires ambition, and supports them in reaching their full potential beyond what’s typically offered at other schools.

Course Structure

The IB Program was introduced to St Peter’s Girls’ School in 2012 as an alternative to SACE. This distinguished pathway is a two-year course and provides our Senior students an academically challenging pre-university course. The Diploma curriculum emphasises both breadth and depth of knowledge.

Students study six subjects as well as three core components:

  • Theory of Knowledge (TOK)
  • Creativity
  • Activity
  • Service (CAS)
  • Extended Essay (EE)

These core areas broaden the educational experience and challenge students to apply their knowledge.

The IB Diploma is highly regarded by tertiary institutions both locally and overseas, opening doors for our graduates around the world.

  • The assessments gave me a chance to research and write about topics I’d chosen and thus made me excited about, and personally invested in my work. Instead of exclusively working on prescribed materials, I could branch out from the course and follow where my curiosity took me.

  • The Higher Level Maths and Science courses were fantastic. We covered so much interesting content in plenty of depth over the two years. They were definitely my most challenging subjects, but also the most rewarding.
