This conversion is based on a direct conversion from whole IB Diploma results to an ATAR equivalent. ACTAC introduced a finer grained conversion equivalent in 2023 which has been updated for 2024 university entry.
Students will receive their results on 3 January 2024 with the fine-grained conversion available on 4 January, 2024.
The additional scale for students who just miss the Diploma award, (e.g., receive a result of 23 etc) but meet IB requirements has also been updated. Universities in ACT, NSW, and Victoria use this scale.
