The title of enterprise training is internal trainer, the title of open class is trainer, and the senior title of college teachers is lecturer. The internal training system is not perfect, and many local training institutions have different evaluations and there is no standard line. In addition to the lecturer, other trainers and internal trainers can verify it. To tell the truth, verification is useless, because the state has not given an accurate organization corresponding to trainers. Lecturers belong to the regulatory body of the Education Bureau. Trainers and internal trainers do not need to work in the school, but they need relevant training experience and experience. I hope I can help you.
