All About Montessori's 4 Stages Of Growth

Maria Montessori outlined four stages of growth, also called the four planes of development. The four stages begin at birth and extend to adulthood; together they make up a holistic look at the process of development and include social, cognitive, moral, and biological changes.

Each stage lasts for six years, but  Montessori also acknowledged that each stage was not meant to be rigid; these are not necessarily linear stages but more like a tide ebbing and flowing. Each stage brings a new set of needs and behaviours. There also sub-categories in each stage of growth. The Montessori products also reflect each stage.

  • Infancy/Early Childhood (Birth to Age 6)

    In the first substage, the child is an “unconscious creator.” Here, the baby is not conscious of learning, but is creating who he or she will become. Around age 3, the child becomes the “conscious worker,” because the child is now able to interact with the world deliberately.

  • It is during this substage that the child begins to learn self-mastery and self-control.They have a great need to make their own choices at this stage. During this stage, children have an “absorbent mind”; they absorb information like sponges.

  • Childhood (Age 6-12)

    This stage of growth is calm and stable. While intellectual growth takes place during this stage, it is not as intense as during the first stage. There are both physical and physiological changes taking place during the second stage of growth as well.

  • Children move from the “absorbent mind” stage to the “reasoning mind” stage. Children want to learn more about the reasons behind things. In the previous stage they wanted to know the “what,” but now they want to know the “why.” During this stage, children also begin to think about their role in the grander scheme of life, which Montessori called “the cosmic plan.”

  • Adolescence (Age 12-18)

    Physical changes become a lot more intense during this stage. Psychologically, the teenager is unstable; he or she becomes very sensitive to criticism. Children develop “social consciousness” during this stage, where the teenager becomes more concerned about their societal role in life.

  • Interestingly enough, Montessori remarked that teenagers actually regress during this stage and are less likely to do what is expected of them. This phase is also marked by a teen’s desire for independence.

  • Early Adulthood (Age 18-24)

    Physical growth is not yet complete; the same holds true for psychological development. This is the stage of development where the adult begins to think about his or her contribution to humanity.
