I don't know how to find evidence for some of the competences as I don't supervise anyone.  I read recently that I can use examples from outside of work but - while I do participate in activities outside of work - I'm not a "leader".  

Yes, I agree.

Also, I've been a contractor for the last few years, so have done lots of short-term things for organisations who don't want to deal me with ever again.

Furthermore, I'm very modest, and not positive about my skills, even though I'm experienced enough.

I would like to go through the process, but I think someone would have to hold my hand every step of the way.  It's rather daunting.

You do not have to supervise people. You can technically lead people as an alternative. In this way you are responsible for delivery etc but not responsible for day to day HR issues etc. 

I know what you mean.  I am much more of a collaborator and don't like to take the credit for anything - even if it was my idea initially.  It feels like bragging and I'm not comfortable with that.  

Thanks Gerard - that's quite helpful actually.
