Think of it as the secret sauce that elevates your resume from “meh” to memorable. In this article, we’ll break down exactly what counts as supplemental information, where to include it, and how to make it work for you. Give your resume that extra edge. Let’s dive in.

How to Format Supplemental Information on Your Resume


Supplemental information can be the unsung hero of your resume. Done right, it enhances your story, highlighting the skills, experiences, or quirks that make you a unique candidate. Let’s break it down step by step so your extra details look intentional, polished, and professional.

1. Decide Where to Place the Supplemental Information

The location of your supplemental details depends on their nature and should be formatted consistently to maintain a professional look. Certifications and technical skills should have their own sections, while hobbies or volunteer work can fit under “Additional Information” or “Interests.” Use clear section headers that match the professional tone of your resume.

  • Certifications: “Certifications & Licenses” or “Professional Development”
  • Skills: “Technical Skills” or “Core Competencies”
  • Hobbies: “Interests”

Make it easy for recruiters to find these extras without feeling like they’re hunting for hidden treasures.

2. Tailor the Information to the Job

Every piece of supplemental information must align with the job you’re applying for. Irrelevant details only dilute your application. If it doesn’t strengthen your case for the role, leave it off.

icon checkExample:
For a data analyst position, include certifications in analytics tools like Tableau or SQL. If you’re in a creative field, focus on showcasing design portfolios or innovative projects rather than unrelated hobbies like cooking.

3. Use a Clean and Simple Format

Presentation matters. Use bullet points for clarity, and avoid lengthy descriptions. Keep the structure consistent with the rest of your resume to ensure it looks polished and cohesive.

icon checkExample:

Certifications & Licenses:

  • Google Analytics Certification, Issued by Google (2023)
  • Advanced Python Programming Certificate, Coursera (2022)

4. Highlight the Most Relevant Details First

Start each section with the strongest, most impactful information. Hiring managers typically skim resumes, so lead with details that immediately catch their eye.

icon checkExample:
In a certifications section, list industry-recognized credentials first, such as AWS Certified Solutions Architect, before adding smaller, less crucial certifications.

5. Incorporate Keywords from the Job Description

Scan the job posting for keywords and mirror them in your supplemental sections. This not only makes your resume more tailored which also proves its chances of passing applicant tracking systems (ATS).

icon checkExample:
If the job listing emphasizes “project management,” include related supplemental details like certifications (PMP) or software proficiencies (Asana, Trello).

6. Include Dates to Show Relevance

Always include dates for certifications, volunteer work, or ongoing projects to provide context and demonstrate that your skills are up-to-date. This can also help show recent growth or ongoing involvement in key areas.

icon checkExample:

Certifications & Training:

  • Certified Scrum Master (CSM), 2023
  • Advanced SQL for Data Analysis, Coursera (2021)

7. Tailor Content to Your Industry

Customize your supplemental information to align with the standards of your industry. Tech professionals should highlight GitHub contributions, while artists should concentrate on portfolios.

icon checkExample for Tech:
“Developed three open-source projects on GitHub, including a Python-based data visualization library with 5K+ downloads.”

icon checkExample for Creatives:
“Showcased branding designs on Behance, earning recognition from two industry blogs.”

8. Limit Supplemental Information to Key Highlights

Avoid overloading your resume with too much detail. Supplemental sections should complement the core content without overwhelming the recruiter. Limit these sections to a few key items that add real value.
If your resume is running over one page because of supplemental info, trim the less impactful details.

9. Proofread Thoroughly for Consistency

Don’t let a typo undermine your efforts. Supplemental information often includes specifics like company names, dates, or technical jargon, which need to be accurate and error-free.

Checklist:

  • Are dates accurate?
  • Are section headers consistent?
  • Have you removed any redundant or irrelevant items?

10. Use Specifics to Add Credibility

Whenever possible, back up your supplemental information with real examples or quantifiable results. Vague statements weaken the impact of your resume.

icon checkExample:

Volunteer Work:

  • Habitat for Humanity, Project Coordinator (2021-Present): Managed volunteer scheduling and fundraising campaigns, raising $20,000 in donations.
  • Local Library, Workshop Facilitator (2020): Organized weekly coding workshops for teens, increasing attendance by 50%.

1. Certifications and Licenses

Certifications and licenses are crucial in fields requiring proof of expertise, like IT, healthcare, or project management. A certification such as “PMP (Project Management Professional)” or “Google Analytics Certified” immediately conveys professional credibility.

List the certification name, issuing organization, and date earned. If possible, include verification details or links. Keep this information in a dedicated section or combine it with professional development to highlight your continuous growth.

2. Technical Skills

Technical skills are vital for roles that require specialized tools or processes. Employers scan for keywords like “Python,” “Tableau,” or “AutoCAD.” Instead of listing generic skills, focus on specifics, such as “Advanced Excel: Pivot Tables and Macros.”

Tailor the list to the job description and consider ranking your expertise level (e.g., Beginner, Advanced). This format gives recruiters a clear understanding of your strengths.

3. Language Proficiency

In a globalized workforce, language skills can set you apart. Clearly define your proficiency as “Fluent,” “Conversational,” or “Basic,” and specify dialects if needed (e.g., Latin American Spanish).

For roles requiring bilingual communication, noting “Fluent in Mandarin, with experience translating technical documents,” adds relevance. Be prepared to demonstrate your skills if asked during an interview.

4. Volunteer Experience

Volunteer work highlights leadership, teamwork, and initiative. Include the organization, your role, and the impact you made. For instance, “Coordinated fundraising for Habitat for Humanity, raising $20,000 for housing projects.”

Volunteering is especially valuable for career changers or recent graduates, helping to fill experience gaps. Aligning your volunteer work with the employer’s values can further enhance your applications interview.

5. Awards and Honors

Awards and honors add credibility and demonstrate excellence, often complementing your professional affiliations to show a well-rounded profile. Academic achievements like “Dean’s List” or professional accolades such as “Employee of the Month” reflect hard work ethic and recognition. Provide the award name, organization, and context.

For example, “Received Best Innovator Award at XYZ Corp for cutting costs by 15% with a new inventory system.” This level of detail gives the achievement weight.

6. Professional Development and Training

Professional development shows your commitment to staying current in your field. Mention courses, workshops, or bootcamps from reputable providers like LinkedIn Learning or HarvardX.

For example, “Completed Data Visualization with Tableau (2023)” or “Attended Leadership Workshop on Managing Remote Teams (2022).” Including recent significant projects your dedication to growing professionally.

7. Personal Projects or Freelance Work

Personal projects and freelance gigs showcase creativity and initiative. For example, “Built a personal finance app with 1,000+ downloads” or “Designed branding for five small businesses, increasing engagement by 20%.”

This type of work is particularly useful if you’re new to a field or building your portfolio. Include links to websites, GitHub profiles, or online portfolios to provide tangible evidence of your skills.

8. Publications or Presentations

Publications and presentations highlight thought leadership and expertise. Include the title, publication or event name, and date.

For instance, “Published ‘The Future of Renewable Energy’ in Energy Journal (2023)” or “Presented at the National Marketing Summit on Digital Branding Strategies (2023).” Academic roles or research-heavy positions especially value this information. Adding links to your work can enhance credibility.

9. Professional Memberships

Active memberships in professional organizations signal engagement and commitment to your industry. Examples include “Member of the American Marketing Association (2020–Present)” or “Active Participant in Women in Tech (WIT).”

Highlight leadership roles like “Chapter President” to further enhance your professional image. Memberships can also reflect strong networking skills, making you a more attractive candidate.

10. Hobbies and Interests

When thoughtfully included, related hobbies can make you relatable while showcasing transferable skills. For example, “Marathon Runner” illustrates discipline and perseverance, while “Photography, with portfolio featured in local galleries,” shows creativity.

Choose hobbies that align with the company culture or soft skills relevant to the role. Avoid generic interests unless tied to accomplishments, like “Reading biographies to inform a blog with 5,000 monthly readers.”
