Principal
At International Sharing School, we believe in Learning Through Sharing to build a better future, providing the best educational experience for our students, acknowledging that every child is different and unique.
We have blended an innovative learning space with the highest quality of teaching to provide our students the opportunities to explore and have fun with their learning. They develop the confidence in themselves and are given a wide range of opportunities to develop and enhance their skills and understanding of themselves as learners in a modern world. We are deeply committed to building a community in which our students develop an understanding of their place within an internationally connected world. With over 50 nationalities represented, our students take part in a truly diverse educational environment which allows them to take their place confidently as active participators in a multiculturally diverse world beyond school.
International Sharing School is an IB continuum school in which we embrace our diversity and celebrate our internationalism at every opportunity. Our teachers are internationally diverse in their experience which provides our students with a broad perspective of real-life connections. Learning through sharing is our vision and we embed this into our daily learning across all phases of the school. This guarantees our children experience a connected transition from the time they are welcomed into the community through to the time they graduate.
We have organised the information available for this school into 10 sections and 39 questions. Click or tap on the name of each section to read more.
