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 spectrum of growth and behavior for each age is normal. Consequently, these guidelines are offered as a way of showing a general progression through the developmental stages rather than as fixed requirements. It is perfectly natural for a teen to attain some milestones earlier and other milestones later than the general trend.
