What is the primary characteristic of on-the-job training methods?

The primary characteristic of on-the-job training methods is that they utilize real working conditions and equipment. This type of training allows employees to learn in the actual environment where they will be performing their tasks, which enhances the relevance and application of the skills being taught. By engaging with equipment and processes they will encounter in their daily work, trainees gain practical experience that can help them assimilate new information more effectively and develop their competencies in real time.

In contrast, other options such as being conducted off-site or focusing solely on theoretical knowledge do not align with the fundamental purpose of on-the-job training, which is to integrate learning directly into the work environment. Additionally, limiting on-the-job training to large group sessions would detract from the personalized, hands-on experience that is essential for effective skill development on the job.
