Eight International Baccalaureate students at one Sydney private school scored the top ATAR of 99.95 compared to six HSC students at James Ruse Agricultural High School, raising questions about whether the alternative qualification gives students an advantage in university admission.
The diploma, which is not allowed to be taught in NSW public schools, was offered at 15 private schools last year as an alternative to the HSC.
When results were released on Saturday, 11 of the state’s 450 IB students, or 2.44 per cent, received the top score of 45, which translates to an Australian Tertiary Admissions Rank of 99.95.
By comparison, 48 out of almost 55,000 ATAR-eligible HSC students achieved the same result, a rate of 0.087 per cent. While the IB students make up a tiny sample of the wider community of school-leavers, the year’s results suggest they were 28 times more likely to achieve an ATAR of 99.95.
