After more than a century as one of Sydney’s most prestigious boys-only schools, Cranbrook School has made history. In January 2026, Cranbrook opened its gates to female students for the first time, welcoming its inaugural cohort of girls into Years 7 and 11. The decision marks one of the most significant shifts in Sydney’s private school landscape in a generation — and it has parents across the eastern suburbs asking the same question: what does this mean for my child?
What Is Cranbrook School?
Cranbrook School is an independent Anglican school located in Bellevue Hill in Sydney’s eastern suburbs. Founded in 1918, it has long been regarded as one of Australia’s leading boys’ schools, known for its strong academic results, extensive co-curricular programme, and prominent alumni. The school caters to students from Kindergarten through to Year 12 and has a strong boarding community.
For more than a century, Cranbrook was a single-sex institution. That changed in 2026.
Why Did Cranbrook Go Co-Ed?
The move to co-education was the result of a multi-year strategic review by the school’s Board of Governors. The board concluded that a co-educational environment better reflects the world students will enter after school, and that the school’s resources, facilities, and teaching expertise were well-suited to serve students of all genders.
Cranbrook is not alone in making this transition. Newington College — another of Sydney’s historic boys’ schools — announced its own move to co-education, with girls joining the school from 2026 as well. The trend reflects a broader national shift, with several long-standing single-sex schools reconsidering their model in response to changing community expectations and enrolment pressures.
What Does Cranbrook Offer Girls?
Cranbrook’s co-educational programme is not simply an add-on to an existing boys’ school. The school has invested significantly in preparing for the transition, including staff training, curriculum review, and the development of facilities and pastoral care structures appropriate for a mixed cohort.
Female students at Cranbrook have access to the full range of the school’s academic and co-curricular offerings, including:
- A rigorous HSC programme across a wide range of subjects
- Extensive sport, including rowing, swimming, tennis, and team sports
- Strong performing arts, music, and visual arts programmes
- Boarding facilities for students from regional and rural areas
- Leadership development and community service programmes
The school’s academic track record is strong. Cranbrook consistently appears in the top tier of NSW HSC results, with high proportions of Band 6 results and Distinguished Achievers each year.
Cranbrook School for Girls: What Parents Are Asking
Since the announcement, Cranbrook has received significant interest from families of girls across Sydney and beyond. Here are the most common questions parents are asking.
Is Cranbrook now fully co-educational at all year levels?
No — not immediately. The 2026 intake welcomed girls into Years 7 and 11 only. The school is phasing in co-education progressively, so the full school will be co-educational once those cohorts move through all year levels. Families considering Cranbrook for a daughter currently in primary school should check the school’s current intake years directly.
How do I apply for my daughter to attend Cranbrook?
Applications for Cranbrook are made through the school’s enrolment office. Given the significant interest in the new co-educational programme, early registration is strongly advised. The school’s website at cranbrook.nsw.edu.au has full enrolment information.
How does Cranbrook compare to other co-educational schools in the eastern suburbs?
Sydney’s eastern suburbs have a number of well-regarded co-educational independent schools, including Scots College (which remains boys-only), SCEGGS Darlinghurst (girls-only), Ascham (girls-only), and Kincoppal-Rose Bay (girls-only). For families seeking a co-educational environment with Cranbrook’s academic pedigree and resources, the options were previously limited. Cranbrook’s transition significantly expands the choice available to families in the area.
Will the school’s culture change?
This is the question Cranbrook’s leadership has been most careful to address. The school has been clear that its core values — academic excellence, character development, service, and community — remain unchanged. What changes is who those values are extended to.
What the Research Says About Co-Education
The debate between single-sex and co-educational schooling has been ongoing for decades, and the research does not deliver a simple verdict. Studies suggest that the benefits of either model depend heavily on the quality of teaching, the school’s culture, and the individual student.
What is clear is that both models can produce outstanding academic outcomes. NSW HSC data consistently shows high-performing students at both single-sex and co-educational schools. The decision for families ultimately comes down to which environment best suits their child’s personality, learning style, and social needs.
HSC Results and Academic Excellence: What the Data Shows
For parents making school choices with an eye on university outcomes, HSC performance is a key consideration. In 2024, across all NSW schools, only 12–13% of all HSC results reached Band 6 — the top achievement band. The proportion of students achieving All-round Excellence (Band 6 in 10 or more units) was fewer than 2.1% of the entire cohort.
Schools like Cranbrook, with strong academic cultures and well-resourced teaching programmes, consistently produce results well above these state averages. But the data also shows that the school environment is only one factor. Individual preparation, consistent study habits, and targeted support — including tutoring — play a significant role in determining outcomes.
