Puberty, Teenagers. Adolescence typically describes the years between ages 13 and 19 and can be considered the transitional stage from childhood to adulthood. However, the physical and psychological changes that occur in adolescence can start earlier, during the preteen or tween years (ages 9 through 12).
Normal Development: Late Adolescence (18-20 Years Old) Adolescence is divided into three stages: early (12 to 14 years), middle (15 to 17 years), and late (18 to 20 years). While certain attitudes, behaviors, and physical milestones tend to occur at certain ages, a wide range of growth and behavior for each age is normal.
