Apprentices work under the supervision of experienced mechanics and attend trade school classes to learn the theory and principles of mechanical systems. This combination of on-the-job training and classroom instruction provides apprentices with a well-rounded education in mechanical services. Apprenticeship programs are typically sponsored by trade unions or trade associations and are recognized by the government as a valuable form of vocational training. Upon completion of an apprenticeship, individuals are often eligible for certification and can become licensed mechanics. Apprenticeship training in mechanical services is an important aspect of the industry and helps to ensure that skilled professionals are available to meet the needs of the building and infrastructure development sector.
