The school ethos reflects the original mission of Mount Temple. Based on this heritage of Protestant, Christian traditions, the school ethos statement states:
All of us are different, all of us are equal.
We respect this diversity. We work to create an environment in the school where all members of the school community feel safe and protected, and enjoy learning, teaching, working and extra-curricular activities. We expect tolerance, politeness, courtesy, co-operation and respect for others and their property.
