Continuing Professional Development (CPD) is how doctors update their knowledge and skills throughout their working lives. This includes all elements of good medical practice - clinical and non-clinical.

External CPD is the category doctors use to record their maintenance of knowledge and skills and usually consists of educational activities that take place outside their normal working environment. 

Doctors require evidence of participation in this category, so educational event organisers MUST provide them with a confirmation of participation (preferably in electronic format)
