About Us

“We discovered that education … is a natural process which develops spontaneously.”

 Established in 1992, Grace Montessori School is a nonprofit school and childcare center, an American Montessori Society verified school, licensed by the Pennsylvania Department of Human Services, and registered as a private, nonpublic school with the Department of Education of the Commonwealth of Pennsylvania.

We are a richly diverse student body and faculty, totally committed to the philosophy of Dr. Maria Montessori. We strive to educate the whole child — cognitively, spiritually and physically — in classroom environments that are large, inviting, and well-equipped with age-appropriate, developmentally designed materials.

As an Episcopal School we value nurturing the whole child. We seek out and welcome the differences of our families, and weave them into the common life of our students and staff. Our guiding principles are designed to help our students become critical thinkers and respectful citizens capable of building an inclusive society and a better world.

Montessori Philosophy

Montessori is a method of education that is based on self-directed activity, hands-on learning and collaborative play. In Montessori classrooms children make creative choices in their learning, while the environment and the teacher offer age-appropriate activities to guide the process. Children work in groups and individually to discover and explore their surroundings and to develop their maximum potential. Montessori material is designed to teach children independence and give them the freedom to engage in their own development according to their own particular developmental timeline.

Montessori classrooms are beautifully crafted environments designed to meet the needs of the children at different stages. The prepared classroom environment lets the child absorb the world around them through work with a wide variety of Montessori materials displayed on open shelves.
