To work as a manufacturing, transportation, and construction worker supervisor, you typically need to:

• have at least a high school diploma or equivalent; and
• have work experience in the career being supervised.

Education after high school

For most types of supervisors, formal training is not required. However, in some industries you must have some formal training. For example, supervisors in aerospace and electronics usually need a bachelor's degree in a related field. Construction supervisors may get a degree in engineering or construction management.

Work experience

This is not an entry-level position. You need several years of experience as a worker in the field you want to supervise. From that experience you learn the work processes, methods, and cycles. However, you can enter some jobs with a bachelor's degree and very little experience.

On-the-job training

Many employers train new supervisors in management theory and human resources. Supervisors may also learn new computer software. This type of training may take anywhere from a single day up to three months.

Military training

The military trains people to become mechanics and repairers. Training varies by specialty. The experience you gain working for the military may qualify you to become a supervisor.
