Stages of Development Series: Adolescence

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.

Separation Anxiety: Why It’s Normal and What You Can Do

By Julie Douglas • September 8, 2025

Every fall, the doorways of classrooms become a place of transition. Children are often excited to skip into their school environment, eager to learn and play. Unfortunately, many children experience some level of separation anxiety, particularly when they are very young. The good news? This is totally normal! Read on to learn more about why, and what you can do to help your child feel good about the time you spend apart. What does it look like? Separation anxiety is completely normal. Most young children experience it at some point, and although it can cause stress for both the child and their parents, it’s actually a healthy part of development, especially during the toddler years. Separation anxiety can manifest in many forms. Parents might see their child display some of all of the following behaviors: Crying Physically clinging to parent Loud protesting Persistent worry when separated from parent(s) Separation anxiety typically doesn’t last very long for most children and resolves itself within a few weeks. Once toddlers begin to realize that their parents will actually return, their fears tend to alleviate. Even older children can experience short-lived bouts of separation anxiety. These times are often even harder for parents, but it’s all perfectly normal! Why does it happen? There are a variety of reasons children may experience separation anxiety, but as we mentioned above, it most often occurs during the toddler years. Any time from about 7 months of age through 2-3 years of age, children may go through a phase during which separating from their parents can be quite upsetting. For infants, it’s about differentiating between strangers and people they know. This is obviously an important and healthy part of their development, although it can be heart wrenching when dropping your little one off with care givers in the morning before you head to work. As children get a little older, the reasons shift toward a fear that the parent may leave and not return. After a period of time, the child learns to trust that the separation is temporary, and the anxious behaviors subside. There are plenty of other reasons why a child may experience separation anxiety. If they are tired, not feeling well, or are experiencing stress or a period of transition in their life, they may feel the need to be closely attached to their parent(s). These feelings are typically short-lived and resolve themselves once the child feels some level of reassurance or once the underlying cause is no longer an issue. What can we do? Each child is different, but the following are some strategies that tend to work well for most families: Set aside some extra time in the morning. The simple act of not rushing can create a sense of calm for both you and your child, but it also leaves a few extra minutes for some cuddles. Create a routine. When your child knows what to expect, they will feel more able to trust that everything is okay. This may mean singing a special song in the car on the way to school, walking to the front door together, and making sure to squeeze in one last hug. Find whatever routine works for you and for your child. Be consistent. Once you’ve established a routine, stick to it. This can be a challenge, but it is so important and will do so much to help a child who is feeling anxious. Of course, life has a way of interrupting our plans and routines (especially when you’re trying to get out the door with a young child!) but try to be as consistent as possible. Don’t linger, but don’t sneak away. Staying too long can intensify feelings of anxiety when you do leave, and leaving without your child’s knowledge isn’t the greatest idea, either. They may experience feelings of worry or sadness, but they will also be more likely to trust if they know when a parent is leaving. Ask your child’s teacher or caregiver for advice. Chances are, they have had lots of experience with separation anxiety in children. Teachers are often masters of distraction and redirection, which can help you make a peaceful exit. What if it’s more? Once in a while, separation anxiety is more than a phase. Again, your child’s teacher is a good person to consult if you’re concerned. If your child is well past their toddler years, if their anxiety is affecting them in multiple parts of their lives, or if behaviors are stretching past weeks and into months, it can sometimes help to talk to your child’s pediatrician. Separation anxiety disorder is a more severe and persistent version of what most children experience. The good news is, even children who experience SAD have options to help them overcome their fears and work toward healthy, trusting, and confident periods of separations from their parents.
