Training programmes for THPs generally require three different categories of trainers:
1. Primary training staff
This group are the primary training staff who are responsible for designing and teaching the major portions of the PHC curriculum for TBAs, herbalists and other types of healers.
2. Members of medical and public health staff
This category are members of the regular medical and public health staff, such as doctors, nurses, and sanitary inspectors who may conduct specific sessions according to his or her specialty area, such as for nutrition, child-birth, water, or sanitation. This category also includes clinical staff who provide specific on-the-job training and often supervision of THPs in the field.
3. Members of the THP trainee group
These can be experienced and capable members of the trainee group who can be enlisted to assist with the training of specific parts of the class or in the field.
