I have two college professors that I got on with very well during my college career, and are among some people that I have considered asking to use as references on my resume. For now, I will be applying for jobs as a tutor or peer editor at the university I will be attending this fall, so I figured that they would be somewhat relevant sources.

Is it a good idea to contact them and ask to use them as sources? Or should I stick to former managers and family friends?
