Who we are?

Ethical Culture Fieldston School is a progressive PreK-12 independent school that has been serving students from throughout New York City and the surrounding suburbs since 1878. ECFS offers a rich curriculum in the arts, sciences, and humanities. A co-ed, nonsectarian school, it serves an inclusive community of about 1,700 students on two campuses -- one in the Riverdale section of the Bronx, and the other in Manhattan.

What is essential about working at our school?

The Ethical Culture Fieldston School has a long history of inclusion and belonging deeply rooted in our mission and the educational philosophy of our founder, Felix Adler. We embrace all aspects of an individual, including their ancestry, family, identity, culture, and beliefs. We affirm both our differences and commonalities and strive to balance individuality and community. In keeping with our progressive tradition, we are dedicated to increasing our students’ cultural literacy to help them understand multiple perspectives and see the world beyond the self.

We expect members of our community to engage in open dialogue about living and learning in an inclusive environment inside and outside the classroom. We see this work, with its creative tensions, as a catalyst for individual and collective growth. On a daily basis, we are committed to making this vision of a democratic, pluralistic, and progressive school a reality.
