So what counts as an experience?

Any experience that has resulted in you developing or applying one or more of the 9 Employability Skills listed on the Skills and reflections.

You have to explain how participating in that experience allowed you to develop or apply whichever skills you’re referencing. If you can explain how you exercised those skills in that experience when you write your reflections, then you’ll have satisfied the CPD ‘eligibility’ requirement and submitted a valid CPD experience.
