Provides information about the Registered Apprenticeship system. Registered Apprenticeship programs are a written plan designed to move an apprentice from a low or no skill entry-level position to full occupational proficiency. A Registered Apprenticeship program is sponsored by an individual business or an employer association and may be partnered with a labor organization through a collective bargaining agreement. Apprentices start working from day one with incremental wage increases as they become more proficient on the job. Apprenticeships range from one to six years, but the majority are four years in length.   Upon finishing the training program, an apprentice earns a "Completion of Registered Apprenticeship" certificate, an industry issued, nationally recognized credential that validates proficiency in an apprenticeable occupation.
