Adolescence is a time of rapid growth and change physically, cognitively, and emotionally. While each young person is unique and develops on an individual trajectory, there are some universal developmental tasks. Our series, Understanding Adolescence: Using a Developmental Lens, explores these key developmental tasks across the three primary stages of adolescence: early, middle, and late.
This section focuses on Early Adolescence, roughly defined as ages 10-14, and outlines the major changes common to this stage.
Developmental Tasks
Adjust to new physical sense of self
Young adolescents experience rapid and profound physical changes triggered by hormones acting on different parts of their bodies.
In early adolescence these include:
- Rapid physical growth and body changes.
- Uneven growth of bones, muscles, and organs, sometimes resulting in awkward appearance.
- Frequent feelings of fatigue.
- Intense concerns with body image; may be self-conscious about growth.
- Worries about being normal, with peers often preceived as the standard.
Adjust to a sexually maturing body and feelings
With the significant changes they experience in adolescence, youth must adapt sexually and establish a sense of sexual identity. This includes incorporating a sense of gender identity; establishing values about sexual behavior; and developing skills for romantic relationships.
In early adolescence:
- Individuals assigned female at birth (AFAB) generally develop earlier than those assigned male at birth (AMAB).
- Young people of all genders experience shyness, blushing, a sense of modesty, and greater interest in privacy.
- Individuals experience emerging sexual feelings and exploration.
- Normal behavior includes experimentation with their own body (masturbation).
- Worries about being normal are normal.
- Contact with potential romantic partners happens in friend groups.
| Physical growth & puberty | Assigned male at birth (AMAB) | Assigned female at birth (AFAB) |
|---|---|---|
| Growth starts (average) | Age 14 (range 12-16) | Age 12 (range 10-14) |
| 1-year average height increase during growth spurts | 4.1" | 3.5" |
| Starting age of puberty (average) | Age 11-12 (range 9-14), individuals continue to grow for about 6 years after the first visible signs of puberty. | Age 10-11 (range 8-13), individuals continue to grow for about 4 years after the first visible signs of puberty. |
| Length of puberty | 3-4 years | 4-5 years |
| Progression of changes |

Define a personal sense of identity
Adolescents move from identifying themselves as an extension of their parents (childhood) to recognizing their uniqueness and separateness from parents. They develop a sense of self as an individual and as a person connected to valuable people and groups. They refine their sense of identity, exploring issues such as: "Who am I? How do I fit in? Am I lovable and loving? How am I competent?" This process often manifests as exploration of alternative styles of dress, jewelry, music, hair, and mannerisms. Teens may struggle to identify a true self amid seeming contradictions in the way they feel and behave in different situations, and with fluctuating levels of thought and understanding.
In early adolescence:
- Identity is influenced by relationships with family members, teachers, and, increasingly, by peers.
- Worries about being normal are normal, with peers being viewed as the standard.
- Often magnify their own problems and feel misunderstood.
- Feel observed by an imaginary audience.
Adopt a personal values system
Adolescents develop a more complex understanding of moral behavior and underlying principles of justice. They question and assess beliefs from childhood and restructure these beliefs into a personal ideology (e.g., more personally meaningful values, religious views, and belief systems to guide decisions and behavior).
Early adolescents:
- Begin to question and try out value systems.
- Move from thinking in terms of "What's in it for me?" fairness (e.g., if you did this for me, I would do that for you), to wanting to gain social approval and live up to the expectations of people close to them - "golden rule" morality. As they become able to see the perspectives of others, they may place the needs of others over their own self-interest.
Renegotiate relationship with parents/caregivers
Adolescents negotiate a change in relationship with parents that begins to balance autonomy (independence) with connection. Overall, the adolescent’s task is one of separating in some ways, while maintaining and redefining connections in others. Through this process, they make room for a more adult relationship that both meets cultural expectations and provides necessary support.
In early adolescence:
- Differentiation presents as being argumentative with their adults.
- Individuals tend to be closely attached to parental figures.
- Their parents are still making most of their decisions for them.
- Their parents’ listening skills can support their development.
Develop stable and productive peer relationships
Peer relationships change during adolescence, giving youth more support and connections as they spend less time with adults and in supervised activities. These peer relationships often compete with parents and schools in terms of their influence on teen’s attitudes and behaviors. As networks with peers broaden, peer relationships become deeper and play an increasing role in shaping an individual's self-concept and interaction.
Throughout adolescence, teens experience three changes in their peer relationships:
- Reorientation of friendships from activity-based relationships of childhood to more stable, affectively oriented friendships based on idea and value sharing.
- Growth of romantic and sexually oriented relationships.
- Emergence of peer “crowds.” Throughout adolescence, friendships become more stable, intimate and supportive, providing a cornerstone for learning about adult relationships.
Early adolescents:
- Experience increasing influence of and connection to peers.
- Start choosing friendships based on affective characteristics (loyalty, trust, and willingness to confide) rather than shared interests and activities.
- Gravitate toward same-gender friends and group activities.
- Begin to label or group their peers (e.g., cliques).
- Experience fear of peer rejection.
Meet demands of increasingly mature roles and responsibilities
Adolescents gradually take on the roles expected of them in adulthood. They learn the skills necessary for these roles and manage the demands of the labor market as well as meet family, community, and citizenship commitments.
Early adolescents are:
- Mostly interested in the present and near future.
- Likely to change vocational goals often.
