IB/HSC Results 2025

The 2025 IB Diploma results exemplify Trinity’s commitment to academic excellence and holistic education. This year, five students achieved the extraordinary accomplishment of a Perfect Score of 45 points, a testament to both individual dedication and the School’s expertise in supporting excellence in this credential.

With 115 Diplomas awarded to one of the largest IB cohorts in the Australasian region, Trinity continues to provide a world-class education that prepares students for success. In 2025, a mean IB score of 37.3, out of a possible 45 points, is extremely strong in comparison to global statistics. Coupled with the size of our cohort, this mean score continues to showcase Trinity ‘s expertise in delivering the IB Diploma to students of all abilities.  

The IB sets a score of 40 as the benchmark for distinguished achievement. Demonstrating the academic depth of the cohort, 43 students earned their Diploma ‘with Distinction’ by scoring 40 or more points. This represents 36% of Trinity’s candidates and, again, will significantly exceed world and national averages that generally sit at less than 20% of the session candidature.  

In a key difference to the HSC, the IB Diploma requires students to complete a CAS component (logged hours dedicated to creativity, action and service), Theory of Knowledge Assessment and an Extended (4000 word) Essay in a subject of the student’s choice. These three Core Components generate 1, 2 or 3 bonus points towards the final score out of 45.  

The current cohort have continued Trinity’s fine achievements in the Core.  Worldwide, less than 15% of Diploma candidates generally receive the full three marks available from the Core. Comparatively, this has long been a source of strength for Trinity students, and in 2025 the results are exceptional: 37% of the cohort reached this outstanding mark of excellence, while 86% of students achieved two or three marks for their Core submissions.  

Focussing on the two most demanding aspects of the Core reveals deep and robust approaches to teaching and learning. Empowering students to craft an appropriate Extended Essay research question of their own making demonstrates Trinity’s culture of supporting students to follow the individual passions underpinning this challenging but rewarding aspect of the Diploma. Once again, strong results in the essay component are noted: 25% of the cohort achieved an ‘A’ grade essay and 70% were awarded the ‘A’ or ‘B’ grade. Turning to the Theory of Knowledge component, 76% of students achieved an A or a B for this unique element of the credential, further testimony to a successful culture of inquiry learning, collaboration, personalised feedback and students’ commitment to lean into challenging academic demands.  

The IB permits students to ‘anticipate’ Standard Level courses – that is, sit the final examination in the first year of Diploma study. This year, Trinity presented seven students from the Year 11 cohort in the Mathematics Analysis and Approaches (SL) course; each of the candidates achieved a Grade 7. Congratulations to these students and the outstanding support provided to them by their teachers and the Mathematics Faculty.  

One of the School’s key measures in assessing credential outcomes is the percentage of students scoring marks in the top two grades or bands. The following courses represent more than half of the course candidature achieving a Grade 7 or Grade 6.  

The HSC Showcase Nominations celebrate the exceptional creative and practical achievements of students across various subjects. These prestigious programs, including ENCORE, Shape, OnSTAGE and ARTEXPRESS recognise the outstanding work produced in areas such as Visual Arts, Music, Drama, and Design and Technology.  

Being nominated for a HSC Showcase is a significant honour, reflecting not only the students’ talent and dedication but also their ability to excel under the rigorous standards of the HSC. These accolades highlight the breadth of creativity and innovation within the cohort and serve as a testament to the quality of teaching and support provided by the School.
