Look at your own direction If you are a training specialist, you will develop in the direction of internal training, such as training supervisors and managers. If you are an assistant trainer, you will develop in the direction of foreign training, such as a professional trainer. As an assistant trainer, you can contact the trainer directly and learn various training skills better, but you may not be familiar with the business of the enterprise. If you are a training specialist, your training skills will not improve so quickly. You need to know the company's business and so on. See which direction you want to go.
