We acknowledge and support the role of parents as the primary educators of their children and work in partnership to promote the spiritual, academic, emotional, and social development of each student. We believe all students deserve an inspiring and well-rounded academic program that prompts critical thinking and meets individual learning needs. We honor students' achievements and promote skills to be productive, contributing citizens in a global society. We value the diversity of our community and instill respect for all people and concern for the needs of the world.
