Which training method involves a craftsman training a skilled worker through a combination of formal learning and long-term on-the-job training?

The training method that involves a craftsman training a skilled worker through a combination of formal learning and long-term on-the-job training is apprenticeship. This approach is characterized by a structured program where an apprentice learns the theoretical aspects of a trade or profession while also gaining practical, hands-on experience under the supervision of a skilled mentor or craftsman. This dual focus helps the apprentice to not only understand the principles behind the work but also to develop the necessary skills in a real-world setting, effectively bridging the gap between theory and practice.

In contrast, job rotation typically involves moving employees through various job roles to develop their skills across the organization, but it does not usually involve a mentorship component specific to a craft. Internships offer practical experience but are often short-term placements and may not have a structured learning component like apprenticeships. Collaborative learning involves peers working together to enhance their skills and knowledge, but does not center around the mentor-apprentice relationship that defines an apprenticeship.
