To validate your resume for an Applicant Tracking System (ATS), you need to check whether its text can be parsed and matched by the software—not whether it looks pretty. The core validation steps are: use standard section headings, avoid tables/text boxes/graphics, include exact keywords from the job description, and save as a plain .docx file. Below, we break down what ATS validation really means, how to test it, and what to fix.
What ATS Validation Is (and Isn’t)
An ATS is software that companies use to collect, store, and filter job applications. When you submit a resume, the system parses it—extracting your name, contact info, work history, education, and skills into a structured database. Validation means checking that your resume’s content is readable by the parser and that it matches the job’s required skills.
Many people think ATS validation is about “beating the robot” with hidden keywords or white text. That’s false and can get you rejected if the system flags it. In reality, ATS validation is about clarity and relevance: making sure the machine can read your text and that your text clearly shows you meet the job requirements.
How ATS Parsing Works
Most ATS platforms (like Workday, Taleo, Lever, Greenhouse) use a parser that reads your document’s text in a specific order. It looks for recognizable section headers—e.g., “Work Experience,” “Education,” “Skills”—and then extracts the text under each. The parser also scans for contact information, dates, job titles, and skills.
Common parsing failures include:
- Text inside tables, text boxes, headers/footers, or graphics (parsers often miss or scramble it).
- Columns (multi-column layouts confuse the reading order).
- Non-standard section titles like “Career Highlights” instead of “Work Experience.”
- Images with text (e.g., a logo with your name) that aren’t OCR-readable.
- PDFs that are scanned images rather than text-based files.
To validate, you can copy your resume’s text into a plain text editor (like Notepad) and see if it reads in a logical order. If it’s jumbled, the ATS will likely jumble it too.
Step-by-Step: How to Validate Your Resume
Here’s a practical checklist you can run through:
- Use a standard layout: Single column, no tables, no text boxes, no graphics. Use standard section headings: “Summary,” “Work Experience,” “Education,” “Skills.”
- Save as .docx: Most ATS systems parse .docx reliably. If you use PDF, make sure it’s text-based (not a scan) and that the text is selectable.
- Run a text extraction test: Copy the entire content from your resume and paste it into a plain text editor. Check that the order is correct and no content is missing.
- Check for keyword matches: List the hard skills from the job description (e.g., “Python,” “project management,” “SEO”). Count how many appear verbatim in your resume. Aim for 80% or more, but only if you genuinely have those skills.
- Use a free ATS checker tool: Many job boards and resume sites offer free ATS scanners. Upload your resume and see how it scores. These tools aren’t perfect, but they can catch formatting issues.
- Test with a real ATS simulation: Some sites let you see a parsed version of your resume. If you can’t find one, use the text extraction test as a proxy.
Common Problems and How to Fix Them
Here are the most frequent ATS issues and their fixes:
- Problem: Your resume is in a two-column layout with skills on the left. Fix: Convert to a single column, placing skills in a dedicated section.
- Problem: You used a PDF with fancy fonts that don’t embed properly. Fix: Use standard fonts like Arial, Calibri, or Times New Roman, and save as .docx.
- Problem: You abbreviated a skill (e.g., “MS Office” instead of “Microsoft Office”). Fix: Spell out the full name at least once.
- Problem: Your job title is “Manager” but the job posting asks for “Project Manager.” Fix: Include both, if accurate, in your work history.
- Problem: You have a “References available upon request” line that takes up space. Fix: Remove it—it’s not needed and wastes parsing space.
How to Choose an ATS Validation Tool
There are dozens of free and paid ATS checkers online. When choosing one, consider:
- Does it show a parsed text preview? That’s the most useful feature—it shows exactly what the ATS sees.
- Does it compare your resume to a specific job description? Some tools let you paste the job posting and then analyze keyword matches.
- Is it free or does it require a subscription? Many free tools are sufficient for a basic check.
- Does it store your data? Be cautious about uploading sensitive personal info to unknown sites. Read the privacy policy.
Remember, no tool can perfectly replicate every ATS. Use them as a sanity check, not as gospel.
ATS vs. Human Review: Why Both Matter
Even if your resume passes ATS parsing, a human will eventually read it. So validation isn’t just about machine readability—it’s about making your resume clear and compelling for people too. A common misconception is that you should stuff your resume with keywords, but that makes it unreadable. Instead, weave keywords naturally into your work experience bullet points.
For example, if the job requires “data analysis,” don’t just list “Data Analysis” as a skill; write a bullet like “Analyzed sales data to identify trends, increasing quarterly revenue by 12%.” That satisfies both the ATS and the human reader.
Costs and Safety of ATS Validation
Most ATS validation can be done for free. Paid tools often offer more detailed reports, but they aren’t necessary for most job seekers. If you do use a paid tool, make sure it’s reputable and doesn’t require a long-term subscription.
Safety-wise, be careful about uploading your resume to unknown websites. Use well-known platforms or those recommended by your university’s career center. Never include your social security number or other sensitive IDs on your resume, as that’s not needed for ATS validation.
Frequently Asked Questions
Does every company use an ATS?
Not every company, but the majority of mid-to-large companies do. According to industry estimates (though exact numbers vary), over 90% of Fortune 500 companies use an ATS. Small businesses might not, but it’s safer to assume they do.
Should I use a PDF or Word document?
Word (.docx) is the safest choice because it’s universally parseable. Some ATS systems have trouble with PDFs, especially if they contain images or unusual fonts. If you must use PDF, ensure it’s a text-based file and test it with a parser.
Can I use tables to organize my skills?
No, avoid tables. They often cause parsing errors. Use a simple comma-separated list or bullet points instead.
What if I don’t have all the keywords in the job description?
Don’t lie. Only include keywords that accurately reflect your skills. If you lack a required skill, consider whether you should apply at all, or highlight transferable skills that are similar.
Does an ATS reject resumes automatically?
Some ATS systems automatically reject resumes that don’t meet certain criteria (like missing a required degree), but many simply rank resumes for human review. Your goal is to get past the ranking stage and into the interview pile.
