In which type of training do new employees practice in an environment before working with real customers?

Vestibule training is the correct choice because it involves a structured learning environment where new employees can practice their skills and procedures before they engage with actual customers. This type of training often takes place in a setting that mimics real work conditions closely, allowing trainees to become familiar with the equipment, software, or processes they will use in their jobs.

The key aspect of vestibule training is its focus on creating a safe and controlled space to learn, making it particularly beneficial for roles that require specific technical skills or customer interactions. By training in this simulated yet realistic environment, employees can build their confidence and competencies without the pressure of real-time customer interactions or the risk of disrupting actual operations. This preparatory step is critical for ensuring that they are fully equipped to handle the responsibilities of their position once they enter the live environment.

In contrast, other types of training mentioned have different characteristics. On-the-job training integrates learning directly with real job tasks but does not specifically emphasize a separate training space. Induction training is generally focused on integrating new employees into the organization and conveying company policies and culture rather than providing hands-on practice. Therefore, vestibule training stands out as the approach specifically designed for practice before engaging with customers.
