Apprenticeships are structured training programs that combine on-the-job learning with related classroom instruction. They allow apprentices to earn while they learn, gaining practical skills and theoretical knowledge simultaneously. Key features of apprenticeships include:

1. Paid Employment: Apprentices are employees who receive a progressively increasing salary as they advance through the program.
2. Structured On-the-Job Training: Apprentices learn through hands-on experience under the guidance of experienced mentors.
3. Related Instruction: Apprentices receive classroom or online instruction that complements their on-the-job training.
4. Mentorship: Experienced professionals provide guidance and support throughout the apprenticeship.
5. Industry-Recognized Credentials: Upon completion, apprentices earn a nationally recognized credential certifying their skills.
6. Progressive Wage Increases: As apprentices gain skills and experience, their wages increase accordingly.
7. Defined Duration: Apprenticeships typically last from one to four years, depending on the complexity of the occupation.
