Fostering Pride, Belonging & Equality


At the International School of Siena, we pride ourselves on being a warm and inclusive community. We know that learning thrives best when students feel safe and happy at school, and therefore, student well-being is central to our work. Building strong relationships between teachers and students is essential to creating a culture of respect, open-mindedness, and continuous learning.

We are proud of how smart all our students look in their IS Siena uniform. Students in the PYP and MYP should wear the official white school polo shirt or T-shirt with the school logo, dark blue trousers/sweatpants or dark blue calf length shorts/skirts, blue zip jacket with school logo. Other official logoed items are available on the OVS website.

Students in Grades 12 & 13 do not have to wear the official school uniform, but they are expected to come to school in smart casual clothing suitable for a learning environment. T shirts should not have logos which might cause offence.
