Adolescence is divided into 3 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.

If you have any concerns related to your teen's own pattern
of development, check with your health care provider.
