On-the-job training is a training method in which employees are trained directly on their job. It is a hands-on training method that allows employees to learn how to perform their jobs in a real-world environment and to be guided and evaluated by experienced people.

Example
A company hires a new employee and places them in a training program directly on their job. New employees will be guided and supervised when performing their duties in a real working environment. New employees will be trained on the processes, tools, and skills needed to do their jobs effectively. The training process will be evaluated and adjusted to ensure that the new employee can complete his or her job independently and effectively.
