References are usually included in the job interview/application process and should be formatted like your resume. Include your relationship to the reference and their contact information.
Most employers will ask for a list of references as part of the job interview or application. References are important to employers. You can market yourself in whatever way you want, but a recommendation from an outside source is key to showing some of the characteristics and skills that may not be as effectively conveyed on paper.
When creating a references page, use the same heading and format as your resume. Also be sure to include your relationship with the reference.
TEN STEPS FOR GETTING PROFESSIONAL REFERENCES
1 Choose the right professor, employer, or supervisor. Ask yourself: Does this person know my name? Have I done quality work in their course or organization? Does this person respect me?
2 Prepare your email request at least 5-6 weeks before the due date. Don’t wait until the last minute.
3 Address the email properly. You should use their formal title in almost all cases.
4 Use “Reference for [your name]” as the subject line.
5 Start the first paragraph by stating what you want: “I am writing to ask if you would be willing to be a job reference for me.” Do not keep him or her guessing.
6 Outline your relationship with the professor, employer, or supervisor in the following paragraph and point out why you have asked them specifically. Tell a little about yourself and why you are interested in the job, scholarship, or internship for which you need the reference.
7 Give them the details. If they need to provide a letter, where does the letter need to go? When do you need it?
8 Close with information on how you will follow-up.
9 Thank them immediately, whether or not they agree to be a reference.
10 If you are fortunate enough to secure the job, send a handwritten thank-you note.
