I'm wondering what is common courtesy when listing references on an application. In my case, it would be professors, but do you necessarily have to tell the profs that you are planning on listing them as a reference?
Did you have a good relationship with your preceptor? You could use him/her as a professional reference. Also, I would ask any reference if you may use them, you never know, they may have a reason for not wanting to provide themselves as your reference.
Always check with your references. It doesn't have to be major, but asking is nice: "Is it ok if I list you as a reference?" Once you start to apply to more jobs, you can say "by the way, I just wanted to let you know I applied to X Y and Z jobs and I listed you as a reference."
You never know - my fiance, who is a paramedic, has had ask people ask him for a reference, and he has told them no, honestly, I can't give you a reference. Better to have one person say no than give you a bad one, right?
Most employers require TWO reference checks If one doesn't alert your references that you are applying at XYZ business, they often to not call back HR or myself as hiring manager!!!!
Therefore, you may be skipped over if another applicants information comes back and ok'd to be hired, they will be chosen over YOU.
I've always informed my references, asking first if it's ok to use them, and then later a quick call or email to inform them that someone will be contacting them re: a job. That's standard. It's never a good idea to list a reference without their permission.
