Employers have realized that life-long learning is important to success. Thus they are sending their employees to courses to learn more. In addition, some adults are going to classes for fun and personal growth. Others are upgrading their skills in order to find jobs or advance in their current jobs. As the number of people moving to the U.S. has increased, so has the need for people to teach English.
Many employers require basic knowledge of English, math, and writing.
Vocational education teachers lead these types of courses. Employment of vocational trainers can be affected by the economy. Most schools receive funding from the government. If the education budget is cut, then vocational trainers may lose their jobs. Many job openings result from people leaving this occupation.
