What Is an ATS Score? (And How to Improve Yours)

Most job seekers apply and hear nothing back. A major reason: their resume never reached a human. An Applicant Tracking System (ATS) scored it too low and filtered it out automatically. Understanding what ATS score means, and what actually moves it, is the single highest-leverage thing you can do to improve your job search results.

What is an ATS score?

An ATS score is a numeric rating (usually 0-100) that an Applicant Tracking System assigns to your resume based on how well it matches the requirements of a job posting. When a company posts a role, the ATS already knows what it's looking for: required skills, years of experience, job titles, certifications, and keywords from the job description.

When you apply, the ATS parses your resume, extracting your text into structured data, and scores it against those criteria. Candidates above the threshold get moved to the recruiter's review queue. Candidates below it are filtered out, often before a single human reads a word.

Major ATS platforms (Greenhouse, Lever, Workday, Taleo, iCIMS, Ashby) all use variations of this scoring. The specific algorithm varies, but the inputs are consistent: keywords, formatting, completeness, and structure.

What factors go into an ATS score?

IceSume's ATS checker evaluates your resume across 22 checkpoints in four categories. These mirror what real ATS systems measure:

1. Content quality (highest weight)

• Does your resume have a professional summary with relevant keywords?
• Do your bullet points start with action verbs?
• Do your bullets include measurable results (numbers, percentages)?
• Are you avoiding personal pronouns (I, me, my)?
• Is there no generic filler like 'seeking a challenging role'?
• Is your resume the right length? (400-800 words for most roles)

2. Structure

• Are section headers standard? (Experience, Education, Skills, not 'My Journey' or 'Expertise')
• Does the resume use a parseable format? (no tables, text boxes, or columns that merge text)
• Is the section order logical? (contact, summary, experience, education, skills)
• Are dates consistently formatted? (Month YYYY throughout)

3. Contact information completeness

• Is your full name present?
• Is a professional email included?
• Is a phone number present?
• Is your LinkedIn URL included?

4. Keyword match (job-specific)

• When you paste a job description, the ATS checker shows which keywords from the JD appear in your resume
• Missing keywords are ranked by importance (must-have vs. nice-to-have)
• The keyword match score improves when you add the missing terms to your skills or summary

What score do you need to pass?

There's no single universal threshold. It varies by company, role, and how many applicants they receive. But as a general benchmark:

• Below 60: very likely filtered out before human review
• 60-74: may pass at lower-competition companies; risky for large employers
• 75-84: competitive, most resumes in this range reach a recruiter
• 85+: strong, above this threshold you're competing on content, not filtering
• Target: aim for 80+ on every application before submitting

The most common reasons ATS scores are low

Wrong keywords

If the job description says "Salesforce CRM" and your resume says "customer database management", you get zero keyword credit. ATS systems match exact strings, not concepts. Copy the exact terms from the job description and use them in your resume.

Keyword matching

Before: Managed customer relationships using our CRM tool and handled data entry for the sales team.

After: Managed customer relationships in Salesforce CRM, maintaining 200+ accounts and logging pipeline data for a 12-person sales team.

Formatting that breaks parsers

Two-column layouts, tables, and text boxes are the most common formatting issue. When an ATS parses a two-column layout incorrectly, your Skills section might end up appended to your last job title, or disappear entirely. Single-column layouts are always safe. Two-column layouts built specifically for ATS (like IceSume's templates) are also safe. The difference is how the HTML is structured under the hood.

Missing professional summary

The summary section is prime keyword real estate. It's where you can naturally include the job title, 3-5 core skills, and your years of experience, all in one readable paragraph that the ATS reads first. Resumes without a summary score 10-15 points lower on average because they miss this keyword-rich section.

No measurable achievements

Numbers in bullet points aren't just for impressing humans. ATS systems trained on millions of resumes recognize that bullets with metrics are more likely to be achievement-oriented. Resumes with zero quantified bullets score lower on content quality metrics in most modern ATS.

How to improve your ATS score in 30 minutes

1. Run your current resume through IceSume's ATS Checker (free, no account needed)
2. Check your score and identify which checkpoints are failing
3. Paste the job description to see your keyword gap, then add the missing terms to your skills or summary
4. Rewrite 2-3 bullets in each role using the APR formula (Action + Problem + Result)
5. Make sure your summary exists and includes the exact job title you're applying for
6. Re-run the checker and verify your score improved above 80
7. Apply with confidence

Does ATS score matter for all companies?

Small companies (under 50 employees) often don't use an ATS at all. A founder or hiring manager reads every application directly. In that case, your ATS score matters less and human readability matters more.

Mid-size and large companies (50+ employees) almost universally use an ATS. So does every staffing agency and recruiter. If you're applying to companies at this scale, assume your resume is being scored before anyone reads it. Optimize accordingly.

The good news: a resume that scores well on ATS also reads well to humans. The same traits (clear structure, strong keywords, measurable achievements, clean formatting) work on both. Optimizing for ATS doesn't mean sacrificing readability.
