Lecturer is the source of the whole training process, and the level of lecturer determines the quality of training. There are basically two sources for training lecturers: one is external employment; The second is the internal lecturer of the enterprise. Limited by space, this paper only briefly introduces the construction of internal lecturer team.

The main tasks of lecturers are to give lectures, compile teaching materials and participate in the setting of training courses. In order to ensure the high quality of the lecturer team, enterprises should formulate a "lecturer qualification certification system", which can be certified from four aspects: professional knowledge, professional experience, achievements and expression ability. The performance of lecturers can be assessed once every six months or once a year, and the survival of the fittest can be eliminated. At the same time, in order to support and encourage lecturers to actively carry out training work, lecturers are given certain time to engage in the development of teaching materials and certain lecture fees and teaching material development fees. Finally, enterprises should help lecturers improve their professional level and organize them to carry out professional training and skills training.
