D

When American students graduate from college, they must find jobs for themselves. But often they get help from their college and university. Every college has a career counseling office. The people who work there help students learn about different kinds of jobs and the chances for employment. Students can discuss their first year of college. Some use the information a counselor gives them when deciding what subjects to study.

For example, a girl student wants to be an engineer, but she does not know what kind. The counselor can tell the girl that, when she graduates in four years, there will be more jobs for structural engineers than for chemical engineers. Therefore, the student may study structural engineering.

The career counseling office also communicates with local and national companies. Company officials often visit the university to talk to students who want to work for them. The career counseling offices arrange these meetings for the company and the students. They also have classes for students. They teach the students how to find a job such as what to say to company officials and how to write letters telling about themselves.

Experts say that American students who are employed when they finish college usually find jobs in their own field of study. Those who must search for months after graduation usually take lower paid jobs, and their jobs are not connected to what they studied in college. The experts foretell that in coming years there will be more jobs for healthy workers, financial experts, teachers and computer scientists.
