Baulkham Hills vs Girraween High School: A Blacktown Guide

Families in Western Sydney shortlisting selective options usually end up with the same two names side by side: Baulkham Hills High School and Girraween High School. Both are fully selective. Both post strong results year after year.

For a family based around Blacktown, the useful question is not which school is better. It is which one fits your child, your commute and your week. Below we compare the two on size, travel, culture and results, using the figures each school published in its own 2024 Annual Report.

Key Takeaways

• Both operate under the NSW selective schools model, so entry comes through the same statewide placement test rather than a local catchment.
• Baulkham Hills is substantially larger, at roughly 1,220 students against Girraween’s 780.
• Girraween sits closer to the Wentworthville and Toongabbie corridor; Baulkham Hills is further north east in the Hills District.
• Both schools report attendance around ten percentage points above the state average.
• Preparation for either starts with the same test, which is where selective preparation and Opportunity Class preparation both begin.

Why These Two Schools Get Compared So Often

Girraween and Baulkham Hills come up together constantly because they draw from overlapping areas, including families around Blacktown, Seven Hills and the wider outer western suburbs.

Both sit inside the NSW Department of Education’s selective system. Entry is decided through one centralised placement test rather than a residential zone, so a family in Blacktown can nominate either regardless of address.

What differs is everything downstream of that test: the trip to school, the size of the year group, the subjects on offer and the daily feel of the campus.

How Far Is Each School From Blacktown?

For families in the Blacktown area, travel is often the single biggest practical factor.

Girraween High School sits closer to the Wentworthville, Toongabbie and Pendle Hill corridor, which for many Blacktown households falls along a more direct route. Baulkham Hills High School is further north east in the Hills District, generally reached via the M2 or arterial roads through Seven Hills and Kellyville. Depending on where in Blacktown you live, that can mean a noticeably longer trip during school-run peak hours.

Test the actual commute yourself on a weekday, by car and by public transport, at the time your child would really be travelling. It tells you far more than a distance calculator.

Bus routes and travel times change with roadworks and timetable revisions, so confirm current options with Transport for NSW before deciding.

How Big Is Each School?

School size shapes daily life more than many families expect before Year 7 starts. A bigger cohort usually means more subject choice and more extracurricular options, alongside a larger campus to navigate and less individual visibility in the early years.

Baulkham Hills recorded a total enrolment of about 1,220 students across Years 7 to 12, making it one of the larger selective schools in the region. Girraween’s 2024 report records 434 boys and 344 girls, roughly 780 in total, which makes Baulkham Hills about half as large again.

That gap is the clearest difference between the two. A larger campus supports a wider spread of elective subjects and co-curricular groups simply because there are more students to fill them. A smaller cohort can mean closer relationships between year groups and staff who know every student by name. Which suits your child depends on how they respond to a bigger environment.

How Do the Academic Results Compare?

Both schools follow the same NESA syllabus documents, so the content taught in Year 12 Chemistry or English Advanced is set centrally rather than by the school. What varies is teaching staff, elective offerings and how each school structures academic support.

Baulkham Hills reported that 47 students, or 23% of its 2024 HSC cohort, achieved an ATAR above 99, with 67% above 95 and 88% above 90. Girraween does not publish an equivalent ATAR breakdown in its 2024 report, though it notes that essentially all of its Year 12 graduates go on to university study.

Both prepare students for the full range of HSC courses, including Extension Mathematics and Extension English. You can read the detail yourself in the Baulkham Hills 2024 Annual Report and the Girraween 2024 Annual Report.

What Is the Culture Like at Each School?

Results tell part of the story. Who makes up the student body, and how included each student feels, matters just as much day to day.

Baulkham Hills reports that 96% of its students come from a language background other than English, and it runs a Support Unit of around 70 students alongside its selective stream. Its 2024 report also notes a $750,000 contribution from the Parents and Citizens association toward a whole-school library refurbishment, and a staffing entitlement of roughly 85 teaching staff.

Girraween is also culturally diverse, with 20% of students recorded from an EAL/D background at the Consolidating level. It describes itself as a fully academically selective, co-educational school, and reported attendance of 94.5% across all years in 2024, slightly ahead of Baulkham Hills and well above the state figure of 83.3%.

How Do Blacktown Families Prepare for Either School?

Whichever school a child eventually attends, the preparation around the test matters more than the name on the gate. Entry to both runs through the same NSW Selective High School Placement Test, taken in Year 6. The test is computer-based and sat at an allocated test centre, commonly a local high school rather than a selective one.

That test rewards reasoning under time pressure rather than content recall, which catches many strong students off guard. We break down the most misunderstood section in our guide to the Thinking Skills paper, and the reading demand behind it in the inferential reading gap.

For primary-aged students working toward the test, our primary school tutoring in Blacktown runs in small groups of one to five students, minutes from Blacktown Station. Fees are published in full on our pricing page, and you can book a free trial before committing to anything.

The Bottom Line

There is no single correct answer between Baulkham Hills and Girraween. The right choice turns on factors specific to your family:

• Travel: test the real commute at school-run times, by car and by public transport.
• Size: consider whether your child thrives with the variety of a larger cohort or prefers a closer-knit environment.
• Subjects: check each school’s published subject list against what your child is drawn to in senior years.
• Culture: visit on an open day where possible and speak with current families.
• Verified data: read each school’s own Annual Report rather than relying on secondhand comparisons.

Both schools are strong. The one that fits your child’s temperament and your family’s week is the one worth nominating.
