What component of on-the-job training builds confidence and competence gained during and after upgrade training?

The component of on-the-job training that builds confidence and competence gained during and after upgrade training is job experience. This is because job experience refers to the hands-on application of skills and knowledge in a real-world setting. When learners engage in practical tasks as part of their on-the-job training, they have the opportunity to practice what they have learned, allowing them to enhance their skills while also gaining a deeper understanding of their job requirements.

Through job experience, individuals can confront and solve real challenges they encounter in their roles, which fosters a sense of accomplishment and boosts their confidence. This continuous practice helps solidify their competence as they refine their skills and adapt to the ongoing demands of their workplace.

Mentorship, on the other hand, plays an important role in providing guidance and support, but it is primarily about the relationship between the mentor and mentee rather than direct skill application. On-the-job evaluation and skill assessment are useful for measuring and ensuring proficiency, but they do not directly contribute to building hands-on confidence and ability like job experience does.
