What do we mean by supplemental information on your resume?"?

Supplemental information is any additional materials, documents, or deliverables that provide extra facts to the resume. If a candidate’s situation is unique, supplemental information can help paint a better picture. It can also provide a comprehensive snapshot of your education, background, and credentials.

Why you'd want to include supplemental information with your resume

If a recruiter or hiring manager asks for information not included in the resume, you’ll need to provide supplemental information. The extra facts provide more context to your resume and elevate your brand and image.

Supplemental information for a resume is also useful for the following situations:

  • Your resume shows unemployment gaps or irregular work periods
  • You apply for a position within an undergraduate or graduate program, which requires supplemental information
  • You have licenses, certifications, or qualifications not listed in the resume
  • You have extra work experience not listed in your resume, such as an internship
  • You are a contractor or business owner with several client testimonials

What else do people consider supplemental information? Below are some common examples of supplemental information.

Letters of recommendation
