teensParents often blame the ups and downs of raising a teen on one or two things such as changes in hormones or the influence of peer pressure. But there’s more to it than that.

Changes in the Teen Years

The preteen and teen years are filled with many changes. Normal teen development is made up of not only biological and physical changes, but also social, emotional, and intellectual changes. A teen is experiencing many changes in:

Teens’ Developmental Tasks

Teens have many developmental tasks to accomplish as they work to figure out who they are, far more than those of infancy and early childhood. According to The Teen Years Explained: A Guide to Healthy Adolescent Development, one way teens figure out their self-concept and their self-esteem is through these five developmental tasks.

Accomplishment of these developmental tasks happens gradually, sometimes independently and sometimes together with another task, and in no set order.

Each teen matures on his or her own timetable. Teens can be ahead of the typical age in one area of development and at the same time, behind the average age in another area. For example, consider a physically awkward 15-year-old boy who has not gotten used to the extra inches he grew in a few months. This same 15-year-old boy might possess wonderful social skills and make friends easily.

What Parents Can Do

Although it can be helpful for parents to remember back to when they were a teen, that isn’t enough. Parents need some basic knowledge of what to expect as their child grows into adolescence.
