Our Mission

Our mission describes our school's purpose. Our vision depicts our desired future. The principles needed to achieve our mission and vision are articulated in our values. Finally, the actions we need to demonstrate to make our mission, vision and values a reality are described in our collective commitments.

We have developed these statements in collaboration with our staff, students and families. They are part of our School Success Plan.


At David Leeder Middle School, we will prepare all students to meet the challenges of a changing society by facilitating and fostering their intellectual, physical, emotional and social development in a safe inclusive learning environment.


David Leeder Middle School will be a welcoming site of excellence. Our school will be an integral part of the community where students, parents and teachers develop and meet the diverse strengths and needs of all learners.
