A career in this field often starts with an apprenticeship or a technical education program. Many individuals begin as an apprentice, which combines classroom instruction with on-the-job training. After a few years, they can advance to a journey-level worker who can perform most tasks without direct supervision. With more experience, they can move into supervisory roles, such as a Line Foreman or Construction Manager. Engineers typically advance from a Transmission Engineer to a Senior transmission line Engineer or Project Manager.
