NIS is an inclusive learning community that is enriched by the composition of different races, ethnicities, cultures, and beliefs, as well as the fact that our students, parents, faculty, and staff are not only heterosexual, but also lesbian, gay, bisexual, transgender, queer (or questioning), and others (LGBTQ+). We believe that all the diversity individuals and families bring to NIS make our school a vibrant, internationally-minded place to teach and learn.

Respect and appreciation for everyone in our NIS community, in all their variety and complexity, are guiding principles as we teach, communicate, play together, and learn from one another. 

Our school recognizes that sexual orientation, gender expression, and identity are a part of development and distinct in the experience of individuals. In this knowing, we seek to be a safe and welcoming school for transgender, genderqueer, and gender non-conforming students and adults where we honour the diversity of gender expression. Our faculty and staff strive to avoid insensitive gender assumptions, to support everyone in their individual expression of gender and identity,  keep an open mind, empathise, and respect.
