Let's temporarily rule out the possibility of misunderstanding the types of trainers, and answer the relevant questions of corporate trainer training positively:
Enterprise trainers belong to the group of trainers who take enterprises as the research object and background. All knowledge structure and ability requirements are around enterprises, including both the business scope of internal trainers (not to be understood as TTT) and the scope of inter-enterprise training.
There are a certain number of authorized institutions in the municipality directly under the central government for the professional qualification certification training of enterprise trainers, and only authorized institutions in other provinces and cities (excluding promotion institutions that recruit students on their behalf but have no teachers and training qualifications). After the training, Ministry of Human Resources and Social Security will issue the national general vocational qualification grade certificate-enterprise trainer certificate (assistant trainer, trainer, normal university).
Although this kind of training belongs to the standardized training of "industry access", as a national labor department, it still has obvious effectiveness and cognitive advantages in China (so-called national general).
This kind of training materials are: basic knowledge 1 (1-3 universal, left one); Two volumes of professional skills-level 3 (teaching assistants) and level 2 (teachers) are bound volumes (in the middle of the picture below) and level 1 (normal university, right), as shown below:
If you want to apply, it is recommended to call directly or consult the local authorized training institution. General human resource managers, psychological counselors, logistics specialists, marketers and other institutions with professional certification training qualifications will have certification training for corporate trainers. You can find it by searching for keywords on Baidu.
