Transformation for every girl: Principal Julie Calder (Selwyn House School)
An early investment in a girl’s education can shape far more than academic outcomes; it can define her confidence, curiosity, and sense of self. Principal Julie Calder of Selwyn House School shares why the primary years are the most powerful window for transformation, and how a specialised, girls-only environment helps students step into leadership and build the foundations for lifelong success.
While common perceptions suggest that the most critical educational investment should be reserved for high school, Selwyn House School principal Julie Calder believes the opposite. It is a conviction backed by global research and proven by the visible transformation she sees in her students daily. As New Zealand’s only all-girls, full primary independent school (Years 1 to 8), Julie explains why these formative years are the absolute key to unlocking a girl’s potential.
Many parents focus on the secondary transition. Why do you advocate for an earlier commitment?
“The transformation we see in our students every day proves that the primary years are the most critical time. The foundations built during these years are the most important for ongoing academic success. At Selwyn House, we specialise in Years 1–8 because these are the years where confidence is built alongside a strong sense of self. We provide a purposeful runway that allows girls to step safely outside their comfort zones and truly grow into their potential before they reach high school. By the time they get to Year 9, the crucial groundwork of building character and resilience is already done.”
How does a girls-only primary environment support the way a student sees herself?
“In our specialised girls-only environment, we normalise every subject and opportunity. Because there are no gender stereotypes in our classrooms or on our fields, every girl feels empowered to reach for her goals without limitations. Whether it’s leading a mechatronics project or taking centre stage in the performing arts, our girls don’t have to compete for space or ‘permission’ to be interested in a subject. We see a distinct increase in creativity and confidence, particularly in fields where girls have traditionally been underrepresented. It is about providing a space where a girl’s voice, passions, and interests all matter equally.”
For a parent unfamiliar with the International Baccalaureate (IB) Primary Years Programme, how would you describe its impact?
“The IB curriculum is a real eye-opener for many, and it is frequently the aspect of our school that parents wish in hindsight they had known more about when first considering their daughter’s education. It is a world-class framework that turns inquiry into a way of life. Rather than just consuming information, our girls learn to ask meaningful questions and solve real-world problems. This approach, combined with our specialist teachers in music, visual and performing arts, science, mechatronics and PE, gives students the tools to navigate a complex world with a grounded sense of self. I always say: ‘Come in and chat to us about how this will be transformational for your daughter.’”
What is the ‘Year 9 Edge’ and the Senior Leadership Academy?
“In larger secondary schools, Year 7 and 8 students are often the ‘juniors’ having to wait their turn for leadership opportunities. At Selwyn House, whether a girl has grown up through the school or joins us for Year 7, they enter our Senior Leadership Academy. This transition is a huge advantage for new students, offering them an immediate platform to find their voice as role models. Our seniors don’t just watch leadership; they practise it daily by running assemblies, instigating local and global initiatives, and mentoring younger students. This creates the ‘Year 9 Edge’ where our graduates enter high school as seasoned, confident leaders whom top secondary schools actively seek.”
You have recently announced the Charlotte Mason Scholarship. Who is this for?
“We are incredibly proud to offer this opportunity grounded in our deepest educational roots. The Charlotte Mason Scholarship is a new, fully-funded scholarship for girls entering Year 7, covering 100% of tuition fees for both Year 7 and Year 8. It is designed to empower students with the skills and optimism to become lifelong learners who enhance the lives of others. It’s a way for us to ensure that more girls in our community can access this exceptional foundation.”
What is the best way for a family to decide if Selwyn House is the right fit?
“There is no substitute for visiting us in person to feel the unique energy of our community. I invite families to join us for a personal tour regardless of their daughter’s year level. The importance of this visit cannot be underestimated; you will be inspired by how friendly and captivating our team and environment are. It is the best way to witness how our tailored, nurturing approach helps every girl thrive.”
