Apprentices

Apprenticeship is a system of training a new generation of practitioners of a structured competency based set of skills. Apprenticeships ranged from craft occupations or trades to those seeking a professional license to practice in a regulated profession. Apprentices (or in early modern usage "prentices") or protégés build their careers from apprenticeships. Most of their training is done while working for an employer who helps the apprentices learn their trade or profession, in exchange for their continuing labor for an agreed period after they have achieved measurable competencies. For more advance apprenticeships, theoretical education was also involved, formally via the workplace and also by attending a local technical college vocational schools or university while still being paid by the employer often over a period of 4–6 years
