Our students across both credentials have managed to achieve at very high levels in a large variety of subjects, which points to the excellence of our passionate and dedicated teaching staff, who go to extraordinary lengths to ensure students have every opportunity to excel and reach their potential.

Also in 2025, our Year 12 HSC cohort broke St Andrew’s Cathedral School’s record for the number of students to be nominated for HSC Showcases! Thirty-five of our students’ major projects have been recognised by the NSW Education Standards Authority, with three of those selected for inclusion in the Showcases.

This year’s nominations were for a diverse range of work across the arts. Nominations include seven for SHAPE (Design and Technology and Industrial Technology), three for ARTEXPRESS (Visual Arts), ten for ENCORE (Music) and thirteen for OnSTAGE (Drama Group and Individual).

IB Diploma Programme 

The School introduced the International Baccalaureate Diploma Programme (IBDP) for Senior College students in 2009 and the International Baccalaureate Middle Years Programme (IB MYP) to Year 7 students in 2016. Since 2016, all Year 7-10 students undertake the MYP. In 2025, the average ATAR of the top 10 per cent of our IB Diploma students was 99.17.

Higher School Certificate

Each year, around 60-70 per cent of our Year 11 students choose to study the NSW Higher School Certificate as their graduate credential in Year 12. Our students are fortunate to have a large breadth of subject choices offered when undertaking the HSC. The 2025 Year 12 HSC cohort performed the best in our history: the average ATAR for the top 10 per cent of HSC students was 97.8 and 70 per cent of HSC scores were 5s and 6s (top two performance bands).

Reporting 

St Andrew’s Cathedral School has three formal methods of reporting on student progress.

They are: 

  • Academic Reports – provide a comprehensive summary of student progress. These are issued towards the end of Terms 2 and 4 for Year 7 to 10, Year 11 in Terms 2 and 3. Year 12 students receive these reports towards the end of Terms 1 and 3. 
  • Parent/Teacher interviews – held at various times throughout the year for each year level – provide an opportunity for parents to meet with individual teachers to discuss their child’s progress.
  • Weekly Parent Digest – emailed to students and their parents every Friday afternoon and gives a brief summary of student progress and involvement. As well as this, there are informal opportunities for parents to discuss their child’s progress through conversations with individual class teachers.
