Apprenticeship training 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. It is a work-based learning model, commonly referred to as a "learn and earn" model, where on-the-job training is combined with relevant classroom instruction. Apprenticeships can enable practitioners to gain a license to practice in a regulated occupation. The apprenticeship model of learning is flexible; therefore, all programs are different. The length of an apprenticeship varies depending on the employers needs and the occupation. Apprenticeships can be time-based, competency-based, or a hybrid of time and competency-based. The related instruction piece can take place during work or after work hours and can be provided at a school, at the employer site, or even online. Upon completion of the program, the apprentice receives an industry-recognized credential. Apprenticeships combine paid on-the-job training with classroom instruction to prepare workers for highly-skilled careers. Apprenticeships are one solution to meet employers talent needs, while allowing apprentices to begin a solid career and grow their skills without taking on large amounts of college debt. Apprenticeships are offered through an employer or the program sponsor, and to become an apprentice, one can search for an opportunity using the Apprenticeship Job Finder and apply.
