At Marin Horizon,   I am heard. I am seen. I am respected. I am known. I have a voice.   Here at Marin Horizon School, we balance academic rigor and structure with imaginative, student-driven learning to prepare students to be critical thinkers in a dynamic world. Academic Program We see creativity and academic discipline not as opposites, but as partners in great learning. Here, students are encouraged to think outside the proverbial box while mastering the fundamentals.  Preschool Ages 2-5 Marin Horizon's Toddler and Primary Programs are designed to nurture the cherished stage of early childhood. Learn More   Lower School Grades K-4 The Lower School years are the essential building blocks of a child's education, laying the groundwork for a lifelong love of learning.   Learn More   Middle School Grades 5-8 The Middle School years are a time of exploration and development, both academically, socially, and as a citizen of the world. It’s a time of extraordinary learning and growth.  Learn More   Challenged & Supported We encourage our students to try hard things, to venture outside of their comfort zones, and view setbacks as part of the learning process. Many students often hold back in traditional classrooms, afraid of looking bad or getting a lower grade—but at MHS, trial and error is celebrated. Students are encouraged to take ownership of their learning, driven by curiosity, tenacity, and confidence. EST.  1977 For nearly 50 years, Marin Horizon has cultivated a community of inclusiveness and academic excellence. Learn more about us. OUTDOOR EDUCATION We get outside. A lot. Even our youngest students explore the trails, hills, and creeks of Mill Valley, discovering the treasures of our local ecosystems and learning to appreciate and care for the natural world around them. Getting outside in our natural world gives our students the chance to be real-world problem solvers, to interact with wild spaces, to safely push their limits and support one another, and to learn about environmental stewardship.
