Four Planes of Development

 

A unique aspect of a St. Catherine’s education is our deep respect for the natural stages of a child's growth. Dr. Montessori identified a series of distinct six-year stages from birth to 24 years, which she called the four planes of development. By understanding these stages, we can better support each child as they grow from infancy to adulthood.

The first and third planes—Infancy (0-6 years) and Adolescence (12-18 years)—are marked by rapid physical and emotional transformation. These are creative periods of self-construction, when children and adolescents experience profound change. In contrast, the second and fourth planes—Childhood (6-12 years) and Early Adulthood (18-24 years)—are more stable stages, characterized by increased intellectual energy and the consolidation of learning.

The unique characteristics of each plane shape how we prepare both the learning environment and the role of the adult in supporting each child’s needs, while removing obstacles to natural development. In our multi-age classrooms, children build confidence and self-awareness as they learn from older peers and eventually become mentors themselves, fostering a strong sense of belonging.

Montessori reminds us that children are not passive recipients of knowledge—they are active participants in their learning journey, capable of deep thinking and meaningful contributions at every stage of life.

As we explore each plane in more detail over the next few issues of The Globe, we hope to offer insights into the natural rhythm of development. Additionally, we encourage you to register and join us for The Montessori Journey on October 10-11—an opportunity to experience how St. Catherine’s responds to each of these vital stages of development.
