Stages of Development Series: Adolescence

Montessori School of Louisville • March 17, 2025

This post is the third installment in our series exploring four stages of human development from a Montessori perspective. The Montessori approach takes a holistic view of growth, recognizing the unique needs of young people at every stage—birth to age six, six to twelve, twelve to eighteen, and eighteen to twenty-four—and adapts learning environments to support natural development at each stage. By understanding these key phases, we can better nurture young individuals as they progress on their journey to maturity.

Adolescence (Age Twelve to Eighteen)


Adolescence is often seen as a turbulent stage in life, sometimes even labeled as dysfunctional or something to endure. However, Dr. Maria Montessori viewed this vital period of human development as a time in our lives that deserves respect and understanding.


In Montessori education, adolescence is honored as a time of transition, a phase of development that, in many ways, mirrors the first six years of life. Just as the early years are marked by rapid transformation and the shaping of the individual, adolescence marks the transformation from childhood into adulthood.


Adolescent Development


The third plane of development, which typically begins at age twelve and continues through the teenage years, is one of significant physical, emotional, and social transformation. This period is characterized by the onset of puberty, hormonal changes, and dramatic physical shifts. 


Adolescents, much like children in the first plane of development, experience rapid change, but this time it is in preparation for adulthood and potential child-rearing. As a result, adolescents require more sleep and are more susceptible to health issues (e.g. acne, depression, and eating disorders).


A key focus during this stage is the conquest of social and economic independence. Humans on the journey to adulthood need to function in social organizations, which requires intellectual and social skills. Adolescents also need to experience how economic interdependency works and they want to learn about different roles in economic systems. To do so, they need the awareness and skills to contribute in meaningful ways. 


Social engagement is how we function as humans. Economic contribution and interdependency is how we meet our needs. Adolescents are no longer passive observers of society; instead, they strive to become active participants and contributors. Like during the first plane, adolescents learn best through hands-on experiences that benefit society, which reinforces their desire to contribute in meaningful ways.


Adolescents as Social Newborns


Dr. Montessori often referred to early adolescence as the "newborn" stage of adulthood, highlighting the vulnerability and transformation that adolescents undergo. This period of rapid physical and emotional development mirrors the developmental intensity of the first years of life. Adolescents are not just growing in terms of physical stature but also in terms of emotional and social maturity.


Much like a newborn, adolescents are learning how to navigate the complexities of the world around them. They are developing a sense of self and finding their place in society. The challenge of the third plane is to help them build this self-confidence and self-worth, while guiding them through the emotional turbulence that often accompanies this stage.


Holistic Development: Physical, Emotional, and Social Growth


Montessori's approach to adolescence is deeply holistic. We emphasize the importance of addressing the adolescent's physical, emotional, and social needs, recognizing that these areas are interconnected and cannot be separated in the developmental process.


Physical Development

Adolescents undergo significant physical changes during this time, including hormonal fluctuations and rapid growth. Brain development continues with an oversupply of gray matter and pruning of neural pathways, which influences behavior and learning capacity.


Key physical needs include:

  • Engaging in physical activity and hands-on work
  • Maintaining a healthy diet
  • Ensuring adequate sleep


Emotional and Psychological Development

Adolescents experience strong emotional swings and are highly self-conscious. They are forming their identities and are very aware of peer perceptions. Balancing these emotions and navigating their evolving sense of self can be challenging.


Emotional needs include:

  • Opportunities to build confidence and independence
  • Safe yet challenging environments
  • Support in self-expression and identity formation


Social Development

Social connections become increasingly important during adolescence. Adolescents seek peer approval and loyalty and often engage in risk-taking behaviors as they establish their place within their social circles. They learn best through collaboration and social interaction.


Social needs include:

  • Opportunities for collaboration with peers
  • Mentorship from adults
  • Meaningful and relevant social engagement


Moral and Intellectual Development


Dr. Montessori emphasized the adolescent’s sensitivity to issues of justice and personal dignity. This stage is a critical time for developing a strong sense of fairness and the desire to contribute meaningfully to society. As they mature, adolescents begin to understand the value of their contributions to the world around them.


Though their intellectual development might seem secondary due to emotional upheavals, it remains essential. As their brains undergo significant rewiring and neural pruning, adolescents still benefit from intellectual opportunities and challenges, as well as strong moral foundations.


The Role of Work and Contribution


Just as it was in earlier planes of development, work remains a vital aspect of adolescence. Adolescents have a strong desire to contribute to society and have their efforts recognized. Through work and activity, adolescents bolster their self-esteem and gain a sense of accomplishment.


The educational model proposed by Dr. Montessori focuses on land-based work and cooperative community living, which provide ways for adolescents to engage in meaningful activities. This model supports adolescents’ physical well-being, fosters social development, and prepares them for economic independence. Through hands-on work, adolescents not only contribute to their immediate communities but also develop a sense of responsibility and understanding of the value of work.


Supporting Adolescents Through Their Development


To meet the developmental needs of adolescents, we need to offer supportive environments. Dr. Montessori envisioned a community where adolescents could live and work together, gaining both physical and emotional nourishment. Providing opportunities for physical activity, collaboration, and self-expression helps adolescents develop into confident, capable adults.


Adolescents need both freedom and guidance. While they push away from adults as they seek independence, they still require boundaries, structure, and mentorship. Adults play a critical role in supporting adolescents as they navigate this transformative stage.


Understanding adolescence through the Montessori lens allows us to appreciate this period as one of profound transformation. By honoring the physical, emotional, social, and moral development of adolescents, we can provide them with the support they need to transition confidently into adulthood. With a holistic approach that integrates meaningful work, opportunities for self-expression, and guidance from adults, adolescents can be empowered to become the capable, interdependent adults society needs.

More Than a Method: Honoring the Legacy of Dr. Maria Montessori
September 1, 2025
August 31 marked the birthday of Dr. Maria Montessori. Thus, we want to take time to honor the roots of this movement, the visionary contributions of Dr. Montessori herself, and our shared responsibility to carry her legacy forward. At the heart of Montessori education is a deep respect for human potential. Unlike traditional models that begin with the adult's idea of what a child should learn, the Montessori approach emerged from deep observation and genuine curiosity. Dr. Montessori did not set out to create a new educational system. Rather, she observed children with scientific curiosity and developed an approach in response to their needs. It’s important to remember that Dr. Montessori was first and foremost a scientist. She was one of the first female physicians in Italy, graduating in 1896 with a specialization in pediatrics and psychiatry. In her medical practice, she encountered children who were often seen as uneducable. However, rather than accept this assumption, Dr. Montessori looked closer. A Discovery That Changed Everything In 1900, Dr. Montessori was appointed director of a university program for children with developmental delays. Observing their sensory-seeking behaviors in bleak institutional settings, she began studying how sensory experiences affect cognitive development. She designed hands-on materials and engaged the children in purposeful activity. The results were stunning: children who had been dismissed by society not only improved, but some went on to pass the same standardized exams given to their peers in traditional schools. Dr. Montessori’s response was not one of self-congratulation. Instead, she challenged the broader education system, asking: If children with significant delays could thrive when given the right environment and tools, why weren’t typically developing children doing better in school? This question launched a lifetime of work dedicated to understanding and supporting the natural development of all children. The Birth of the Montessori Method In 1907, Dr. Montessori opened her first classroom, the Casa dei Bambini, in the working-class neighborhood of San Lorenzo in Rome. Tasked with overseeing daycare for children too young for public school, she began by introducing simple, practical activities, starting with self-care and environmental care. She also provided an array of materials designed to engage children’s hands and minds. The transformation was extraordinary. Children who had previously been described as wild and unruly became calm, focused, and joyful. They took pride in their appearance and their surroundings. They concentrated for long stretches of time, developed social awareness, and, unprompted, began asking to learn how to read and write. Dr. Montessori was fascinated by what she called “spontaneous discipline” and the deep love of work she observed in the children. Through observation and experimentation, she continued to refine the materials, the environment, and the adult's role. Education Rooted in Development What emerged was a revolutionary approach: an educational philosophy based on the science of human development. Rather than seeing the adult as the source of knowledge and the child as an empty vessel, Dr. Montessori recognized that children come into the world with innate potential and a deep drive to learn. Montessori education supports this natural unfolding by honoring what Dr. Montessori called human tendencies, such as exploration, orientation, order, communication, work, and repetition, through carefully prepared environments that meet the specific needs of each developmental stage. The adult's role is not to instruct, but to guide, observe, prepare, and support. This vision of human development extends beyond the individual to a larger understanding of humans as part of a cosmic web of interrelationships. In this interconnected world, every part plays a role in maintaining balance and harmony. Humans have a unique place in this system, and our role requires conscious awareness, humility, and stewardship. In addition to fostering rich academic growth, Montessori education cultivates mature, adaptive, and compassionate individuals who are capable of making meaningful contributions to our interconnected world. The Enduring Impact of Montessori’s Vision Dr. Montessori eventually left her medical practice and professorship to fully devote her life to this work. She lectured around the world, trained teachers, wrote extensively, and advocated for children’s rights. She also always insisted that the focus remain on the children, not on her. Through decades of scientific observation, experimentation, and cross-cultural study, Dr. Montessori discovered that children, when provided with the right conditions at the right time, flourish. Her insights have stood the test of time. Today, there are approximately 15,000 Montessori schools worldwide, with over 3,000 located in the United States alone. For over a century, Montessori education has empowered children to reach their full potential—academically, socially, and emotionally. Yet Montessori is not just about individual success. It’s about building a better society. We know that children are not just preparing for the future. They are the future. By focusing on children’s holistic development, we are supporting a generation of individuals who are more connected to themselves, to one another, and to the planet. Carrying the Legacy Forward Dr. Montessori’s vision asks us to do more than remember her birthday. We need to believe in children, observe them closely, and prepare environments that honor their needs. This also means that we, as adults, approach our role with humility and a sense of curiosity. Our job is to accompany children as they create the future. In this way, Montessori education becomes not just a method, but a movement, one rooted in peace, interdependence, and the full development of the human being. Thank you for being part of this vision. Together, here in Louisville, Kentucky, we are carrying the Montessori legacy forward, not only by what we teach, but by how we believe in the children before us. Come visit to learn more!
