Exceptional IB Diploma Programme results

The International Baccalaureate Diploma Programme (IBDP) results for our 2024 cohort were released this morning. We are thrilled that our students achieved excellent marks, with the largest number of IBDP students the School has ever had, achieving above 95 and 90 ATAR, and above 40 and 42 overall IB scores (see table below).   

Our IBDP Duxes are Rama Chadda-Harmer, Callista Christabel and Ezekiel Surjadinata, who all achieved a stunning score of 44/45. Our median Diploma point score across all students was 38, as compared to a world average of 29. Our median ATAR was 95, and across our 24 subjects and 35 courses, 70% of all grades were a 6 or 7.  

For the IBDP, students are required to study six subjects – three at Higher Level (HL) and three at Standard Level (SL), all of which are 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.  

Between 2020 – 2022, the IB Organisation took out some of the examination components and lowered grade boundaries to account for the COVID effect across the world. 2023 was the first year since COVID that students had to sit all of the examination components and were assessed against pre-Covid grade boundaries. To enable comparisons – we have included a table below that show our results against 2019, pre-COVID and last year which was our previous best. It should also be noted that UAC (University Admission Centre) have also made the ATAR conversion harder each year i.e. this year is the hardest it has ever been to achieve above 90, 95 and 99 ATAR. For example, last year an IB score of 34+ was equal to an ATAR of 90+. Whereas this year an IB score of 35+ is equal to a 90+ ATAR, which is a full grades difference.
