We believe in developing each student to their fullest potential. This involves providing both a rigorous academic program and a science-based foundation for human development. 

Developmental Science is the integration of neuroscience and developmental psychology. It offers us a scientific foundation for healthy individual formation. In contrast to academic testing alone, it provides a more integrated educational framework through which educators can apply a range of immersive curricula and experiences to foster healthy human development as well as advanced academic readiness. 

Being successful means having the Agency to make active choices about one’s life path, possessing the Competencies to adapt to the demands of different contexts, and incorporating different aspects of oneself into an Integrated Identity.
— “Foundations for Young Adult Success” - June 2015

Developmental science points us to three essential elements for a healthy passage through middle school:

line break

1. Space for Self-Exploration


“Who is that in the mirror?!” Not only are their bodies changing daily, an adolescent’s sense of Self is expanding rapidly. Young teens are consumed by a heightened experience of their changing emotions, beliefs and self-awareness. If these capacities are consciously developed, students can build the ‘non-academic’ skills – mindfulness, emotional intelligence, resilience, and others – that research indicates correlate with long-term success more than any other factor.


2. A Safe Social Environment


Middle school is the most socially-influenced time of our lives. Peers become trusted more than parents. A positive, safe, pro-social environment and authentic relationships at school are essential for healthy identity formation.


3. Connection to the Real World.


As students enter adolescence, they crave greater autonomy and independence. They are highly curious about how the world works, and loudly resist what doesn’t feel “Real” to them. Their academic motivation depends on a direct sense of relevance and agency.

An “Action-Research” Learning Organization

We know a lot more about educational science than we have successfully implemented in schools today. Modern research in neuroscience teaches us how our brains learn. Developmental psychology outlines the optimal environment and experiences for healthy identity formation. Experiential, student-centered learning is more effective than traditional instruction. So… how do we integrate this growing body of research into practical school design on an ongoing basis?

Our answer: A Lab School for Developmental Science. 

To be effective, schools themselves must become “Learning Organizations”, constantly applying research, assessing impact, and adapting techniques to optimize student development. Weekly faculty observation, reflection, and professional development is woven into the schedule.

Following three years of research, Millennium School was launched in Fall 2016 as an innovation lab for adolescent developmental science. We actively partner with professors from several leading universities such as Stanford, UC Berkeley, and UCSF among others, to study and implement transformative learning methodologies.

For students, this translates into an engaging educational experience that breaks many molds. Students co-construct their own learning environment, projects, and assessments. They are actively involved in the action research of what works and doesn’t. And nothing drives engagement in middle school like empowering students as architects of their own adventure.



We celebrate diversity as a portal to ourselves and a peaceful global community

I can see myself in all things and all people around me.
— Sanskrit Phrase

Millennium School strives to create a diverse community of students and families. We believe that inside each of us is a unique wisdom that reflects and enhances our collective humanity. 

We seek out diversity of thought, culture, color, sexuality - and all other forms of being - in order to reveal these unique qualities and embrace each other with compassion. We believe that together we are stronger, more creative, and more authentically ourselves.

We practice diversity by inviting people from all walks of life to join us in our intentional community. You will find that the educational curriculum and learning practices reflect our worldview, and we encourage students to step out of their box and explore multiple perspectives daily. 

We value each soul’s gifts, story, and contribution equally.  

Partnership with SMART: Only 9% of low-income students earn a college degree. We are proud to partner with SMART, a San Francisco non-profit organization, and work together with them to close the achievement gap by offering participating students access to an academically rigorous school with scholarships and other forms of support.

Our Founders' Story

After ten years leading a national nonprofit serving middle-school kids, Chris Balme turned his eye toward creating a model for middle school that better prepares students for real-world success. Jeff Snipes spent 16 years running a global leadership development firm working with Fortune 500 companies; after selling the business, he wanted to focus on the pivotal adolescent years as the root of developing authentic future leaders. 

The common thread between the two of them was the belief that school exists not just to prepare kids with knowledge, but also to develop the skills and mindsets that lead to meaningful, happy, and purposeful lives. They both came to see developmental psychology as a scientific foundation for achieving this aim, and they were introduced by leading adolescent psychologist and best-selling author Madeline Levine.


Chris Balme: Co-Founder & Head of School

Chris is an educator and social entrepreneur, passionate about creating organizations that help students reach their full potential. Previously, Chris was Co-Founder and CEO of Spark, a national non-profit he built over 10 years to improve student success in middle and high school. Spark placed students in apprenticeship programs in organizations ranging from Google to city government, and earned widespread recognition for its ability to motivate students to succeed in school and beyond. Chris has received the Ashoka Fellowship, the Draper Richards Fellowship for social entrepreneurship, as well as the Bay Area Jefferson Award for Public Service. Chris earned degrees in Psychology and Business from the University of Pennsylvania and Wharton, and has taught with Breakthrough Collaborative and in the Philadelphia public schools.

A Space to Invent, Design, Create



Our school is based at 245 Valencia Street, in the heart of the vibrant Mission district. Our building includes one wing of main classrooms, a maker space, a full size gymnasium, a large multipurpose room, a commercial kitchen, a courtyard (connecting to the adjacent Greek Cathedral) and an outdoor terrace for eating lunch or meeting outside. We're part of the bustling Valencia Street corridor, with cafes, restaurants, shops, and small businesses all around. 16th Street BART and several MUNI lines are nearby. Directly across the street is the San Francisco Friends School, a fellow progressive school whose team we are lucky to count as close colleagues.  




San Francisco Is Our Classroom



Think big. Millennium students live and learn in the real world. Our classroom extends beyond the walls of the Clubhouse and pours into the surrounding neighborhood community. A short walk away students regularly explore City Hall, the San Francisco Public Library, a large portion of the city's performing arts institutions, several outdoor fields and parks, and a vibrant neighborhood full of cafes and shops. Millennium students venture out into San Francisco one afternoon per week for “Real-World” learning experiences. These range from professional apprenticeships, to developing urban gardens, community service projects, and field trips to universities, labs, businesses and technology centers. 


Learning in Nature



Think bigger. The Bay Area is a national treasure of natural beauty. Adolescents thrive outdoors and feel a sense of inner harmony and social connection when our classes are held in nature. Under the guidance of trained wilderness guides, Millennium students start and end the school year with week-long expeditions into the Northern California wilderness. We integrate hands-on environmental science studies by exploring local beaches, tide pools, estuaries, redwood forests, mountain lakes and state parks throughout the year. Students pack in, study together, connect with nature, and leave with a deeper sense of stillness and comfort with the outdoors.


Daily Schedule


School Hours:
8:30am - 3:30pm
Monday - Friday.

Drop-off window:
8:00 - 8:30am

We offer after-school programming from 3:30 - 6:00pm each regular school day. The program operates for free from 3:30 - 4:30, and for a fee from 4:30 - 6:00pm. Students have access to a Maker Space with arts and tinkering programs, space for quiet study or project work, and numerous clubs, from Model UN to Robotics. 



Annual Calendar

We've created a unique calendar, focused on supporting deeper learning experiences for students. While the start and end dates are similar to many other schools - the 2018-19 school year will start on August 27, 2018 and end on June 7, 2019 - it's how we use that time that's different. 


Terms: Millennium School has five terms each year, each approximately six weeks long. Within each term, students focus on two "Quests" at a time. These Quests are interdisciplinary classes, enabling students to deeply explore problems and projects which link to the real world. See our blog post here on the "Questions" that each Quest explores. Students spend most of each morning in their Quest, able to go deeply into their project topic, while in the afternoon they have a rotation of Math, Foreign Language, Creative Expression & Physical Expression classes.

Intersessions: Before and after each term, we have a one week "intersession." Intersession is an opportunity for even deeper and more focused learning. Students may spend the week apprenticing with a local company; doing an educational trip; designing and completing a challenge project; or participating in a whole-school simulation, for example if Millennium School turned into Ancient Greece for a week. This is not a vacation period; school is still fully in session at the same hours. The first and last intersession of the year are both outdoor expeditions, rich with opportunities for learning about oneself, building resilience, and forming a strong bond with fellow students and faculty.
