Learning for Life

Montessori education nurtures the whole child, fosters independence, develops self-esteem, and produces a love of learning that lasts a lifetime.


Our School

Castlecrag Montessori School is a parent-run, non-denominational co-educational preschool and kindergarten that offers Montessori classes for children aged 3–6 years.



The Montessori classroom is a supportive and nurturing environment carefully prepared with self correcting materials to facilitate independent learning and exploration.



The first step to enrolling your child is to make an appointment for a classroom observation. This is the best way to appreciate the uniqueness of a Montessori Education.

Castlecrag Montessori school is located on Sydney’s Lower North Shore and has students from Castlecrag, Northbridge, Willoughby, Roseville, Chatswood, Crows Nest, Greenwich and Artarmon.
