Mark Day School is a fully accredited, independent, coeducational school for students in grades Kindergarten through 8th Grade. Throughout the school's history, we have remained focused on providing a challenging program in a nurturing and supportive environment.

Our defining characteristic is a rich and balanced program delivered by an innovative and passionate faculty marked with humor and kindness. Visionary stewardship from our administration and a highly capable and supportive board of trustees have allowed us to engage in thoughtful strategic planning to provide best in 21st-century teaching and learning.
