What is crucial for a worker to be considered Competent?

For a worker to be considered competent, possessing sufficient experience and qualifications is essential. Competence goes beyond merely having theoretical knowledge; it requires the application of skills and expertise that come from practical experience. This means not only understanding the tasks at hand but also having the background and training that enable the worker to execute them effectively and safely.

While completing required safety training is important, it is not sufficient on its own to establish competence. Competence involves a comprehensive understanding and the ability to perform tasks appropriately, which can only be achieved through a combination of relevant experience and formal qualifications. Knowledge of workplace regulations is also beneficial, but knowing the regulations does not guarantee that a worker can apply that knowledge in practical scenarios. Similarly, the ability to supervise others is relevant but does not directly contribute to an individual's own competence in performing their specific job functions.

Thus, the focus on experience and qualifications ensures that a worker has the necessary foundation to fulfill their role effectively, thereby making option B the correct choice.
