The International Baccalaureate, more commonly known as the IB, is a secondary school credential founded in 1968 in Geneva, Switzerland. It is different from the ATAR, but widely popular in Australia due to its universal application. If you are planning on getting an IB diploma in South Australia, this article has all the information you need to know.
What Is The IB?
The International Baccalaureate was designed to provide a universal, standardised and more importantly, transferable diploma for students who would move abroad.
Upon entering year 11, Australian students can choose the educational curriculum (ATAR or IB) they would like to pursue in order to complete their high school diploma. Whilst the ATAR used to be more popular, more and more students are now opting to undergo the IB program due to its challenging curriculum, and potential benefits upon applying for university.
Find out more about the IB curriculum in this KIS Academics blog.
How Is The IB Different From The ATAR?
The IB curriculum is known to be more vigorous and demanding than the traditional Australian certificates.
- For starters, in certificates such as the VCE and HSC, only results from year 12 assessments count towards a student’s ATAR. In the IB, however, both year 11 and 12 content counts towards the final grade.
- Secondly, the only compulsory subject in standard credentials in English (or a related subject such as Literature). On the other hand, in the IB, students must study one subject from six different subject areas.

Can I apply To Australian Universities With An IB Diploma?
Australian Universities definitely accept students who completed the IB Diploma. Some even provide credit exemptions, such as University of Adelaide.
For university admission in Australia, your IB scores will be converted into ATARs. Over the years, this conversion has caused some controversy, with some arguing that the conversions are overly generous, while others say otherwise.
