Thank you for your interest in Sussex School!


Since its founding in 1971, Sussex School has been dedicated to providing a progressive learning environment that enables students to become motivated, mindful members of any community. Our flexible learning environment allows students to be engaged, work collaboratively as well as independently, and to find success in, and passion for, school, learning, and our world.


We accept applications on a rolling basis throughout the school year for all grades K-8.

It is important to accept only those children for whom we can make a reasonable prediction of success in our unique, progressive program. Sussex seeks a diverse population and does not discriminate based on race, creed, color, ethnicity, religion, sexual orientation or gender identity.

"As a parent, the most striking thing about Sussex is how much my kids enjoy going to school. This was a foreign concept at prior places. The engaged faculty, creative opportunities, and an emphasis on learning (rather than busy work) make Sussex School a place where my children thrive."

Andy Tegeder, current parent
