ATS systems are built around the assumption that resumes follow conventional structure. They expect to find standard section headers in predictable places, and they're programmed to extract and categorize the content that follows.
When you use non-standard headers, the system often can't find the content you intended it to read, or it miscategorizes it entirely. The result is that entire sections of your resume become invisible or are evaluated in the wrong context.
This is one of the most common and easily fixable ATS parsing problems. Here's exactly what headers work, what headers break things, and how to audit your own resume for header problems.
How ATS Systems Use Headers to Parse Your Resume
To understand the problem, you need to understand how ATS parsing works at the header level.
When an ATS processes your resume, it looks for specific, conventional section labels to know where different types of information are located. It searches for "Work Experience" or "Professional Experience" to know where to look for employment history. It searches for "Education" to find degree and certification information. It searches for "Skills" to identify relevant competencies.
The parser is essentially pattern-matching against known header formats. When it finds a recognized header, it knows what type of content to expect next and how to categorize and score that content appropriately.
When you use a non-standard header, the system either fails to recognize it as a section header at all, or it miscategorizes the content that follows. A section labeled "Where I've Worked" instead of "Work Experience" might be read as general text rather than employment history, causing your job titles, companies, and dates to be scored differently than intended.
Headers ATS Systems Reliably Recognize
These are the standard section headers that every major ATS platform is programmed to recognize and parse correctly:
Work Experience
This is the most standard header for your employment history. ATS systems immediately recognize it and know to extract job titles, companies, employment dates, and achievement descriptions from the content that follows.
Professional Experience
An equally recognized alternative to "Work Experience" that serves the same function and is parsed identically by ATS systems.
Experience
A shorter alternative that still signals employment history clearly to the parser.
Education
The standard header for degree, certification, and educational achievement information. ATS systems look for this header to identify your academic credentials, graduation dates, and institutions.
Skills
The most critical header for ATS keyword matching. ATS systems weight content under a Skills header heavily for keyword alignment, since skills are core to job matching. Always use a clear Skills header rather than hiding skills within your experience bullets alone.
Certifications
A recognized header for professional certifications, licenses, and credentials. This is particularly important in fields where specific certifications are required or heavily weighted.
Core Competencies
An alternative to "Skills" that some ATS systems recognize, though "Skills" remains more standard.
Technical Skills
A recognized sub-header if you want to separate technical competencies from soft skills, though a single unified Skills section remains the most standard approach.
Summary
Recognized by most systems as an introduction section that appears at the top of your resume before employment history.
Professional Summary
An alternative that serves the same function as Summary.
Volunteer Experience
A recognized header for volunteer work that the ATS treats similarly to paid employment, extracting positions, organizations, dates, and accomplishments.
Languages
A recognized header for language proficiency, particularly important for roles requiring multilingual ability.
Awards and Recognition
Recognized for highlighting awards, honors, or noteworthy recognition received.
Headers That Cause ATS Parsing Problems
These are creative, personalized section headers that sound good to human readers but confuse ATS systems and often make your content invisible or miscategorized:
"My Journey" instead of Work Experience
The parser doesn't recognize this as an employment history section, so it may not correctly extract job titles, companies, or dates. Your experience becomes harder for the system to properly categorize.
"Where I've Been" instead of Work Experience
Same problem. The parser doesn't know this is employment history and treats it as general narrative text.
"Core Competencies" without a clearer Skills header
While some systems recognize this, "Skills" is more universally understood. If you use only "Core Competencies" and no dedicated Skills section, some ATS systems may miss your skills entirely.
"Areas of Expertise" instead of Skills
This creative alternative isn't as reliably recognized as "Skills," and some parsers may miss or misweight the content under this header.
"What I Know" or similar creative skill section headers
Non-standard headers confuse the parser about what content should be treated as skills for keyword matching purposes.
"Education and Training" instead of "Education"
Combining these into one header is fine, but burying education under a creative header alongside training can cause the parser to miss formal degree information.
"Accomplishments" without a clear Work Experience section
If all your achievement content is under an "Accomplishments" header without corresponding job titles and employment dates in an Employment History section, the parser can't properly connect achievements to specific roles and time periods.
"Technical Background" instead of Skills
The parser may not recognize this as a skills section, potentially missing technical keywords that are critical for job matching.
How to Audit Your Resume Headers
Take five minutes right now to check whether your resume headers are ATS-friendly.
Go through your resume and list each section header exactly as written. Compare each header against the "Recognized" list above. Any header that doesn't closely match a standard format needs to be changed.
For example:
-
- "My Work History" should become "Work Experience"
- "Technical Expertise" should become "Skills" or "Technical Skills"
- "Where I've Worked" should become "Professional Experience"
- "Training and Credentials" should become "Certifications"
The changes are simple but can meaningfully improve how an ATS parses and scores your resume.
The Plain Text Test for Headers
The most reliable way to confirm your headers are working correctly is the plain text export test. Select all content in your resume, copy it, and paste it into a plain text editor like Notepad or TextEdit set to plain text mode. Read through the resulting text.
Your headers should appear clearly, followed by the relevant content. If your headers are there and the content that follows them makes sense in plain text, your ATS parsing is likely fine. If headers are missing, garbled, or the content beneath them appears scrambled or out of order, you have header or formatting problems to fix.
The Relationship Between Headers and Keyword Scoring
Headers don't directly contribute to keyword matching scores in most ATS systems. The keyword scoring happens based on the actual content beneath the headers, not the header labels themselves.
However, headers indirectly affect scoring by helping the parser understand what type of content to expect. When the parser correctly identifies content under a "Skills" header as skills, it applies appropriate keyword weighting to those terms. When it misidentifies content under a creative header, it may underweight those same keywords or miss them entirely.
The header itself doesn't score points, but using the right header ensures the content beneath it is evaluated appropriately.

Frequently Asked Questions
Can I use custom headers if I also include standard headers?
Using both custom and standard headers creates confusion for the parser and looks unprofessional. Stick to a consistent, standard set of headers throughout your resume.
What if my industry uses non-standard section names?
Industry-specific terminology should go in the content beneath standard headers, not as the header name itself. For example, use "Experience" or "Professional Experience" as the header, then include industry-specific role titles and context in the bullet points beneath it.
Do I need to use all these standard headers?
No. Use only the headers that apply to your situation. A recent graduate might use Work Experience, Education, and Skills. An executive might add Certifications and Awards. An international candidate might add Languages. Only include headers for sections you actually have content for.
Can I have multiple sub-headers under one main header?
You can, but it should be used sparingly. For example, under Skills you might have "Technical Skills" and "Leadership Skills" as sub-headers. However, avoid creating a confusing hierarchy. Most resumes work fine with a simple, flat header structure.
Will fixing my headers alone improve my ATS score?
Headers are one component of ATS compatibility. Fixing problematic headers helps ensure your content is properly parsed and weighted, but your overall score also depends on keyword alignment, formatting, and content quality. Fix headers first, then check your complete score against job descriptions.
The Bottom Line
Headers are a foundational element of ATS compatibility that many job seekers overlook. Fixing non-standard headers to use recognized, conventional alternatives costs almost nothing in terms of effort but can meaningfully improve how an ATS parses and evaluates your resume.
Go through your resume right now and audit your headers. Replace any creative alternatives with standard formats. Then test your updated resume to confirm the changes have improved your ATS compatibility.
