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 2025 university entry.
Students will receive their results on 17 December 2024 with the ACTAC calculated IB Admissions Score (IBAS) fine-grained conversion available on 18 December, 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.
