If you see an NP or a PA, is 'doctor' the correct title to give them? They're not full fledged doctors but what else would you call them?
A masters level NP can go on to get a doctorate in NP. I'd call them "doctor".
Not sure about PA's.
NP's have to go into a specific field, are often well versed in that field. As such, I tend to put them ahead of PA's, but it depends on the individual.
