One way of classifying training is by the degree of activity expected or required of trainees. On one end, the lecture method and videotapes are generally the least active (or most passive) form of training. Other approaches such as computer-based instruction or videoconferencing are moderately active. At the other extreme, highly experiential methods such as outdoor training, role-playing exercises, games, and simulations demand the greatest amount of activity or action from trainees.

Training approaches can also be grouped into two broad categories: on-the-job methods, which typically occur in the employee’s normal work setting, and classroom methods, which typically take place away from the job. Computer-based training (CBT), for example, can be implemented using a computer at an employee’s desk or work-station, in a company classroom, or even at an employee’s home.
