At Mount Roskill Grammar School, we take pride in behaving in a way that brings credit to our school, our community and ourselves.

These ideals are underpinned, enhanced and enriched by the values of:
- Manaakitanga through uplifting, fostering and nurturing the mana of each person.
- Whanaungatanga through fostering relationships and cherishing diversity, seeking the support of parents, families and whanau and making good connections between people.
- Tūmanakotanga through demonstrating aspiration, and excellence, through a growth mindset, creativity and resilience.
Vision
Our students will be successful, powerful learners who are active and responsible citizens
Mission
In a safe, supportive environment, MRGS will provide learning opportunities for each student to strive for excellence, realise their potential, and develop understanding of social responsibility and respect for individual and cultural differences.
