Beyond Band 6s: The Quiet Revolution in Australian Education

A recent Herald analysis has shed light on several schools that have made remarkable improvements in their Higher School Certificate (HSC) results. However, the real story lies not just in the numbers but in the quiet revolution taking place within these institutions.

Crestwood High, a public non-selective school in Sydney’s north-west, is among those that have seen significant gains. According to the analysis, Crestwood has lifted its average HSC score across subjects to 80 last year, outperforming its previous average over the past three years. The key to this success lies not just in the numerical improvement but in the approach taken by the school.

Principal Tania Wright attributes the school’s success to a combination of factors, including teacher expertise and a focus on sharing knowledge within the school community. Staff present each other with presentations on successful teaching methods, providing an authentic perspective that resonates with students. This emphasis on collaboration and mutual support is not unique to Crestwood; research suggests that top-performing schools often share similar traits.

A closer examination reveals a common thread among these schools: they place a strong emphasis on teacher expertise, data-driven instruction, and a culture of high expectations. Lake Macquarie High, another school featured in the analysis, has seen a 10 percentage point increase in its average score between 2023 and 2025 under the leadership of Principal Brendan Maher. His approach is built around building connections with staff, fostering a culture of professional learning, and encouraging teachers to mark HSC exams.

This initiative not only improves results but also provides invaluable feedback for both teachers and students. The findings have significant implications for education policy. For too long, the focus has been on the band 6 results themselves rather than the underlying factors driving these improvements. By examining the methods used by top-performing schools, policymakers can gain a clearer understanding of what works and how to replicate it across the sector.

Dr Jennifer Buckingham’s comments highlight the importance of a strong learning culture in HSC success. She emphasizes the value of collaboration, explicit teaching, and effective feedback. However, there is also a more nuanced story here – one that speaks to the broader challenges facing Australian education. The emphasis on band 6 results has often created a culture of competition, where schools are pitted against each other in a quest for prestige.

This can lead to an overemphasis on selective students while those who struggle with HSC-level subjects are left behind. However, the real revolution taking place is not just about achieving higher scores; it’s about creating a more inclusive and supportive learning environment that values every student’s potential.

As Maher notes, his school’s focus is on helping students “who don’t think they can get the HSC” – a message that resonates with many schools struggling to reach disadvantaged communities. By examining these approaches and sharing best practices, policymakers can create a more effective support system for teachers, students, and families – one that prioritizes collaboration over competition and equity above all else.

The coming months will be telling as these schools continue to push the boundaries of what is possible in Australian education. As we close this chapter on HSC results, it’s clear that there is much to learn from these schools. But what will be most telling is not the number of band 6s achieved but the depth of commitment shown by educators who are willing to challenge conventional wisdom in pursuit of a more just and equitable education system for all.
