Thornton campus

Welcome to Thornton Academy

Thornton Academy is an independent, private day and boarding school for students in grades 6 through 12. Thornton is co-educational and non-sectarian.

Since its founding in 1811, Thornton Academy has been a center of inspiration, innovation, and community in Saco, Maine. We prepare students for a changing world through our curriculum, facilities, extra-curricular opportunities, and student support. Students are encouraged to step outside their comfort zones, to try courses that challenge and intrigue them, and to take deep dives into subjects that spark curiosity. Engagement continues after-school, through many clubs, activities, community service, and athletics.

Our Mission

Thornton Academy prepares students for a changing world, challenging all to learn, grow, innovate, and succeed.

What Sets Us Apart

Support During a Crucial Period of Growth and Development

At Thornton Academy, students can express individuality while discovering their future aspirations. Our school community is warm and welcoming. We are a school where students build strong relationships with dedicated teachers and student friendships that last a lifetime. Our faculty and staff recognize that each child has strengths and challenges, and takes into account the well-being of individuals at each stage of social, emotional, and intellectual development.

Diversity That Fosters Compassion and Respect

With students from more than 30 local towns and more than 50 countries worldwide, we value the diversity and multiculturalism of our community. The geographic, cultural, and socioeconomic diversity of our student body creates a unique and dynamic learning environment that fosters a greater appreciation of not only our individual differences but also the values we share. Among those shared values are Thornton Academy’s Core Pillars — Respect, Responsibility, Compassion, and Investment. These values guide our work and reflect how we treat one another within our school community. 

An Individualized Approach to Supporting the Future of Each Student

Bearing in mind today's competitive global economy, our experienced college counselors work with students one-on-one in grades 9-12 to plan college and career trajectories. We encourage real-world experience through internships, job shadows, and part-time work. Our university partnerships offer students the opportunity to test out areas of study even before university enrollment.
