If you've heard the term "ATS score" but aren't sure exactly what it means or how it's calculated, this guide will clear it up. Understanding your score is the first step to improving it — and improving it is the first step to getting your resume in front of a real human.

What an ATS score actually is

An ATS score is a number — usually expressed as a percentage — that represents how well your resume matches a specific job description. Different ATS platforms calculate it differently, but most consider: keyword match percentage, section completeness, formatting compatibility, and skill alignment. The score determines whether your resume appears in a recruiter's search results and how high up the list it ranks.

What is a good ATS score?

• Below 50%: High likelihood of being filtered out before a human sees it
• 50–70%: Might appear in results but ranked low. Recruiter may not reach it.
• 70–80%: Competitive. Likely to appear in top results for most roles.
• Above 80%: Strong. Consistently in the top tier of candidates.

CV Chackr's scoring uses a similar model. Upload your resume to see where you currently stand and exactly which improvements will move your score up.

What lowers your ATS score

• Missing keywords: The biggest factor. If the job description mentions "SQL" 4 times and your resume doesn't, your match score drops significantly.
• Formatting issues: Tables, text boxes, and multi-column layouts prevent ATS from parsing your content correctly. Even correctly-spelled keywords get missed if they're inside a table.
• Non-standard headings: If ATS can't find your Experience section, it can't score it.
• Missing sections: No summary, no skills section, or no education section all reduce your completeness score.
• File format issues: Image-based PDFs or unusual file types score very low or zero.

The fastest ways to improve your score

In our experience, three changes move the needle most: adding missing keywords from the job description (see our keyword guide), fixing formatting to a clean single-column layout (see our formatting guide), and ensuring all standard sections are present with correct headings. Most resumes gain 15–25 points just from these three fixes.

Score vs human judgment

A high ATS score gets your resume in front of a recruiter. But it doesn't guarantee an interview — that depends on the human read. Once your ATS score is strong (70+), focus on making your bullet points impactful and your summary compelling. Run through the ATS resume checklist for a comprehensive pre-application review.
