The Western Australian International School System




The International Baccalaureate (IB) Diploma Programme is an internationally recognized curriculum, designed for secondary school students between the ages of 16 and 19 years that aims to foster internationally-minded and well-rounded students. The DP curriculum is the best preparation for those who are moving onto further education as it produces young adults with a broad academic base, inquiring minds and diverse social interests. It is respected by leading universities across the globe.


The IB DP Curriculum model consists of six subject groups and a core programme.

IB diploma students are required to study six subjects chosen from the six subject groups concurrently for two years. A student has to take at least one subject from each group except for group six (arts and electives), which allows the option of taking another subject from groups 1 – 4.

At least three (no more than four) subjects are taken at higher level (240 teaching hours), while the other subjects are taken at standard level (150 teaching hours). The choice of SL and HL courses is based on students’ interests, strengths, and future plans.



Over the course of the two-year IB Diploma Programme, students study six subjects chosen from the five subject groups, complete an Extended Essay, follow a Theory of Knowledge (TOK) course, and participate in Creativity, Activity, Service (CAS).

IB diploma

Each IB subject is assessed on a scale of 1 – 7 with a score of 4 considered a “passing grade”. This score is calculated based on a combination of internal and external assessments throughout the G11 – 12.

Each subject is graded from 1 – 7 and the combination of TOK and the Extended Essay can contribute up to 3 points to the Diploma. A student can be awarded up to 45 points.
