Montessori’s Developmental Approach

Our whole curriculum is organized to serve students' developmental needs through carefully devised mixed-age classrooms. Students proceed through a detailed curriculum as a natural, enjoyable experience that satisfies his or her inner drive to learn and grow.

The 4 Planes of Human Development

Dr. Maria Montessori, trained as a physician, used her scientific background to develop an innovative approach to understanding child development. This approach divides the child’s life into four six-year stages which together span birth to age twenty-four. At Mountaintop, we serve children through the first three of these stages. Our faculty members observe each child throughout his or her development in order to understand what support is needed and to ensure appropriate guidance and challenge.
