For each TWI program (Job Relation, Job Instruction, Job Instruction, Job Methods and Job Safety) there is the possibility to train internal trainers.

These trainers can then learn the method in their own company and apply it in practice. In this way one is able to organize the capacity development internally. The Train-the-trainer training can take place in your own company. If there is a special demand, this training is also organized in an open training (together with trainers from different companies).

Before someone can become a TWI-trainer, this person must first have done the training for users and have gained their own experience with the method.

If sufficient experience with the method has been gained in practice, someone can complete the Train-the-Trainer training. With the help of the standardized training manual a small group (4-6 persons) will practice the training in a 40 hour training week
