Wrapper Image Quicklinks - Community Panel Image Quicklinks Who We Are Optional Link Our Curriculum Optional Link Admission Process Optional Link Meet Our Community We are a Bay Area independent school community founded on diversity, inclusivity, and lifelong learning. At Mark Day School, each student, faculty and staff member, and parent and guardian is known. There are many ways we celebrate individuality, honor differences, and come together, from twice-weekly all-school assemblies to Kindergarten and 8th grade buddies to parent/guardian gatherings. Learn more about our community from the people who know it best. I am grateful to be part of the Mark Day community because I receive an enormous amount of support and encouragement from colleagues and families to explore new ideas and incorporate them into the English and history curricula. The first people our son wants to share his adventures and accomplishments with are his teachers. He respects and adores them with no bounds. As parents, we feel the exact same way about the Mark Day staff, and the thoughtfulness and diversity of the school's programs and curriculum. Mark Day School provided a supportive, warm community focused on the joy of learning. I value my connections with teachers and peers at Mark Day and attribute much of who I am today to the school! We feel so lucky to have landed at Mark Day School when our children entered their middle school years. The educational experience is so thoughtful and purposeful - the school sets a high academic bar, but equips students with the full agency and constant support to meet it.
