Teachers in these institutions also need to receive "teacher class" training or "tutor" training and assessment on the basis of receiving relevant basic training. Take the training of primary emergency personnel of the Red Cross as an example. Trainers of these training courses must hold first aid certificates, and then participate in teacher training and assessment organized by the Red Cross to obtain the qualification certification of Red Cross trainers. Trainers of the American Heart Association are required to attend "mentor" training. Take basic life support as an example. First of all, they must obtain a basic life support certificate before they are eligible to participate in the training of basic life support teachers. Those who have obtained certificates through training can become training lecturers.

Let me tell you the truth. On the one hand, I'm afraid these certificates are not cheap. Besides, I'm afraid it's impossible for you to do this part-time, because you have to belong to an institution with first aid training services. Some of the Red Cross belong to volunteer training teachers, and some are long-term fixed trainers. Many authorized institutions of the American Heart Association are large hospitals, and the training instructors are all doctors in hospitals.
