Students need to attend lectures to acquire official certification. In the past, however, we sometimes couldn't hold certain lectures because there weren't enough students attending. On the other hand, DVD and Internet training sessions tend to be one-sided, and instructors couldn't conduct their lessons while making sure that all of the students understood the content. Countermeasures were also needed to offer a uniform level of lectures to each class in order to maintain a high passing rate. As a result, we began to consider introducing a system where we could deliver lectures to various schools in real-time while communicating with the students by providing live question-and-answer sessions.
