Chestnut Hill Academy is a private, secular, coeducational day school recognized for providing an exceptional learning environment that emphasizes high academic standards, a low student-to-teacher ratio, and a strong emphasis on leadership. The school caters for approximately 375 Kindergarten through Fifth Grade students.

Our students typically matriculate to leading private secondary schools including The Bush School, Eastside Preparatory School, Eastside Catholic, Forest Ridge, Lakeside, Overlake, Seattle Academy, and University Preparatory, as well as the local public schools. 

Our progressive academic curriculum provides a wealth of learning opportunities supplemented by experiential field trips, enrichment activities, and service-learning projects to help children reach their full potential. The Academy’s curriculum develops a broad foundation of knowledge and mastery of skills so that children become competent and confident learners as well as productive, responsible, and ethical members of today’s world.

"My children have attended Chestnut Hill Academy since Kindergarten.
You will not find a more inclusive, rigorous, and character building primary education provider in the greater Seattle area.”
