Generally, adolescence begins at age 11–12 years and ends between ages 18 and 21. Most teenagers complete puberty by age 16–18 years; in Western society, however, for educational and cultural reasons, the adolescent period is prolonged to allow for further psychosocial development before the individual assumes adult status. The developmental passage from childhood to adulthood includes the following steps: (1) completing puberty and somatic growth; (2) developing socially, emotionally, and cognitively, and moving from concrete to abstract thinking; (3) establishing an independent identity and separating from the family; and (4) preparing for a career or vocation.
