     Having a part-time job is an important part of growing up for American teenagers. It can teach them

important skills that will be useful for the rest of their lives. And many teenagers find that making their own

money gives them a sense of pride and freedom.

     American teenagers are allowed to do part-time jobs at the age of 14. During the school year, teenagers

may go to work a few times a week after school, and work for longer at weekends.

     In summer, top part-time jobs for teenagers include at camps, swimming pools and amusement parks.

These jobs are great for those who want to be active and have fun while making money.

     Some of the most stressful jobs include teaching, nursing, and police work. These skills help to prepare

teenagers for their later lives. When they grow up, the students with work experience are more likely to

succeed than those without work experience.

     A favorite job for many teenagers is babysitting, and they can start before the age of 14 if their parents

agree. As long as they stay in the house and make sure the kids are okay, babysitters can do their homework,

babysitters have lots of freedom.
