Apprenticship is a system for training a new generation of
practitioners of a trade or profession with on-the-job
training and often some accompanying study.Apprenticeships can also
enable practitioners to gain a license to practice in a regulated
occupation. Most of their training is done while working for an employer who
helps the apprentices learn their trade or profession, in exchange for their
continued labor for an agreed period after they have achieved measurable
competencies.
