Avoid one of the most common resume mistakes and don't put references in your resume unless requested by the job announcement or employer.
References are a vital part of the hiring process and employers request them for a variety of reasons.
Most of the time they are used to validate information found on your resume.
Employers generally want at least three references, but it's a good idea to have a list of 5 to 7 available.
A list of references should be compiled before sending out your resume.
Take some time to brainstorm and on a blank piece of paper write down the names of family members, friends, co-workers, teachers, supervisors, managers, and former employers.
Contact the people on your list and ask them if they would be willing to be a reference.
Once your list of references is compiled take some time to prepare them for the potential employer contact.

• Let them know what kind of work you're looking for.
  
• Provide them with a copy of your resume (take time to talk it over).
  
• Verify their contact information: name, address, phone, position/title, email, etc.
  
• Verify how they would prefer to be contacted: phone, email, or mail.
  

The types of questions asked usually depend on the relationship you have with your reference.
Are they personal or professional? A professional reference like a supervisor or formal employer may be asked more technical questions related to the job announcement and employment history.
General questions asked of a reference are:

• How do you know or what is your relationship to the applicant? How long?
• How do they get along with other people?
• How is their job performance? Are they on time?
• What else should I know about this person prior to hiring him or her?
• Do you recommend anyone else I should speak to about the client?

Remember! The person you list as a reference should be someone who can attest to your abilities and/or confirm your qualifications when contacted by the potential employer.
Again, do not put references in a resume! When requested by the employer or job announcement put your references on a separate page included with your resume.
