Why Apprenticeship?

Apprenticeships provide a high-quality, structured pathway into a career, built on clear standards that lay out the requirements of an apprentice’s job. This means that apprentices know what they need to learn, and employers map a pathway to success within their organizations.

State of California 5 Point Action Plan.

Unlike most interns, apprentices are paid employees who earn a paycheck for their work. Apprentices’ wages typically start at about 50 percent to 60 percent of their eventual wages, and their pay goes up as they progress through their programs and master more skills. Moreover, because training is part of the job, apprentices do not have to forgo income from employment in order to pursue education and training. An apprenticeship provides a young worker with an immediate job, steadily rising wages, and a gateway into a successful and sustainable long-term career. This is especially important for young adults, as the unemployment rate for Americans under age 25 is still nearly 15 percent more than double the national rate of unemployment.
