Registered apprenticeship program sponsors identify the minimum qualifications to apply for a program. The eligible starting age can be no less than 16 years of age; however, individuals must usually be 18 to be an apprentice in hazardous occupations. Program sponsors also identify additional minimum qualifications to apply, (e.g., education, ability to physically perform the essential functions of the occupation, proof of age.) All applicants are required to meet the minimum qualifications.
