Best ever results by 2021 IB Diploma cohort


Another exceptional year for IB Diploma graduates

We are delighted to announce the outstanding results of our International Baccalaureate Diploma Programme (IBDP) 2021 cohort. They are the best IB Diploma results in the school’s history. An outstanding 14 per cent (out of a cohort of 44 students) achieved an ATAR over 99; 46 per cent achieved an ATAR over 95 and 80 per cent achieved an ATAR over 90. The average ATAR for the top 50 per cent of students was 97.3.

Our IB Diploma duxes are Dylan Nguyen and Gemma Gardiner (pictured). Both achieved perfect scores of 45 out of 45 and an ATAR conversion of 99.95. For those unfamiliar with the IB Diploma, students study six subjects (three at Higher Level HL and three at Standard Level SL), which are each graded out of 7. They can then receive three additional points for the Extended Essay and Theory of Knowledge subjects, making a maximum grade point score of 45 (99.95 ATAR). This is the first time we have had students achieving 45 out 45 – a huge congratulations to Dylan and Gemma.

Dylan intends to pursue further study in computer science in either Australia or the United States and is awaiting results from a variety of scholarship applications. “I’m not sure where I might end up, but I’m likely to begin my studies at the University of NSW, UTS, ANU or the University of Melbourne,” he said.

Gemma is keen to stay close to home and has received a scholarship to Sydney University to study a combined law degree with either arts or science. “I’m not completely sure yet what I will do; I got an early offer from UTS to study a Bachelor of Laws and Bachelor of Forensic Science, which I’m really interested in, but I’ll decide after the formal university offers come out,” she said.

Our average IB Diploma point score across all students is 37, which compares well to the world average of 29 – a wonderful outcome for our school.

I am sure you will agree that there is so much to celebrate as a school community.
