Q: How many is too many references to send with an application when references are required?
A: If the prospective employer asks for 3 references, anything more than that is too many. If they don’t specify and you have room for 2 or 3 on your resume or in your cover letter, that’s fine. Otherwise, you can make a separate References page, with the same header as on your cover letter and resume, and include up to 5 or 6 varied references (e.g., 2-3 school/work references/1-2 community/volunteer references, and a personal reference). If the application is electronic, submit the number of references requested by the format or add another, if permitted, if it’s a truly great reference or someone with ties to the employer.
Less can be more, more can be too many. As in Goldilocks, just right is best. Use your instincts and this advice to guide you each time you submit your references.
