Semester STEM Teacher-Upper

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, non‑sectarian 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.

The Upper School, located in the Bronx, is comprised of approximately 600 students and 80 faculty members.

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.

We are seeking a STEM Teacher for City Semester, our interdisciplinary, experiential semester program for juniors in our Upper Division for the 26/27 School Year. This unique role combines teaching our science course—an Ecology elective that explores natural and urban ecology through a systems lens—with our math course, which integrates precalculus topics and data analysis.

The ideal candidate is confident teaching across STEM disciplines and has demonstrated experience with collaborative/co‑teaching models, as well as a passion for experiential and project-based learning. They employ a range of pedagogical approaches (e.g., direct instruction, cooperative group work, and project-based learning) and are excited to teach students from a wide range of backgrounds in a values‑based community. Qualified candidates also demonstrate a commitment to fostering equity, belonging, and inclusion within and beyond the classroom.

A passion for alternative learning models and a commitment to lifelong learning are essential.
