Sometimes you have a point of view. Then, something will change that point of view.
My point of view was that you only need a current in date First aid at work (FAW) certificate and a teaching qualification to teach FAW or Emergency First Aid At Work (EFAW). People were offering "First Aid Instructors" courses and this appeared to just be another cash cow to me. However, my point of view has had to change. Why? Because of the questions that people who are currently teaching FAW/EFAW ask in FaceBook groups.
