First published in 1980 with help from WHO. Our updated version has been edited to make it shorter and more manageable. It is designed to help teachers running longer courses (around 6 to 12 months).
The book was originally written specifically for Health Care Staff. But if you want to train workers in a different field, read the manual and see if, in your mind, you can replace each health example with another from your own field. The basic principles of training stay the same whenever you train someone to do a job.
