Should I List My RN License in the By-Line?

[shunthor]

Hi. I'm an RN and also a certified health coach (CHC). I'll be writing some articles for a health coaching organization. So, my question is, when do you list your RN license in the by-line? Would it be appropriate to list my RN license while I write health coaching articles? I've seen some people always list their RN license in by-lines and some who only do it when writing a research article. How do you know when to list your RN license as a writer and when not to do it?

For example...

By: Name, BSN, RN, CHC     (OR)      By: Name, BSN, CHC

I've attempted to search online but didn't find an answer. Hope you can help me. TIA.

You should list your RN license in anything related to healthcare or when being an RN is relevant. In any situation where I felt it was relevant to list "BSN" I would also list "RN"
