Asking preceptors to be a reference?

I'm several years out of pharmacy school now but have only held two jobs. I recently interviewed for a new job and they're now asking for references. I would prefer to not ask people at my current job for references for obvious reasons. The new employer specified it is okay to ask professors and teachers if you are a recent graduate. Do you think it would be okay to ask preceptors from several years ago?
