What Is an ATS Score? How Resume Scores Work and How to Raise Yours

You pasted your resume and a job post into a checker and got a 58. Is that failing? Will the employer's software throw your application away? And which of the 23 suggestions on the screen actually matter?

An ATS score is an estimate of how closely your resume matches one specific job description and how cleanly software can read it. It is useful as a diagnostic and misleading as a grade. This guide explains what the number measures, how real applicant tracking systems rank candidates, what a good ATS score looks like, and the edits that raise it without turning your resume into a keyword list.

You'll also get a worked example that takes a sample resume from 54 to 81, a diagnostic table for low scores, and a 15-minute routine you can run before every application.

What an ATS score actually measures#

The phrase "ATS score" gets used for three different numbers. Mixing them up causes most of the confusion, so separate them before you edit anything.

The checker score is a simulation#

When you use a free checker, nobody at the employer is involved. The tool parses your file, pulls keywords from the job description you pasted, and estimates how much overlap exists. The number is a proxy for what an employer's system might conclude. It is not a reading from that system.

That matters because the tool can be wrong in both directions. It can flag a "missing" keyword that a real system would match through a synonym. It can also give you credit for a keyword that sits inside a table the employer's parser would scramble.

The employer-side ranking is real, but hidden#

Some applicant tracking systems do rank applicants. Workday's HiredScore assigns letter grades from A to D based on how well a resume matches the qualifications in the job description, according to Workday's grade reference. Greenhouse's Talent Matching sorts candidates into tiers such as Strong, Good, Partial, and Limited match, and its data processing FAQ states that the feature does not automatically advance or reject anyone.

You will never see those grades. You can only influence them by meeting the stated requirements clearly, in words the software and the recruiter both recognize.

Why the distinction matters for your edits#

If you treat the checker score as the employer's verdict, you will over-edit. You'll paste in every phrase the tool lists, including soft skills and filler terms that real ranking systems barely weigh. If you treat it as a diagnostic, you'll use it to find two things: parsing failures and missing must-have qualifications. Those are the issues that cost interviews.

For background on how these systems store and route applications, read what an applicant tracking system is and how it works.

How ATS score checkers calculate your number#

Most checkers follow the same five steps, even if their interfaces look different.

1. Parse your resume into fields: contact details, job titles, employers, dates, education, and skills.
2. Extract keywords from the job post: hard skills, tools, certifications, job titles, degree requirements, and sometimes soft skills.
3. Compare the two lists, using exact matching, stemming (so "analyze" matches "analysis"), and in better tools, synonyms.
4. Weight each match by category and by how prominent the term is in the job post.
5. Add format checks such as file type, section headings, and whether dates were readable.

The weights are where tools differ most. The chart below shows one plausible weighting. It is a model to help you think about priorities, not any vendor's published formula.

Exact match vs. semantic match#

Older keyword tools only credited an exact string. If the post said "project management" and you wrote "managed projects," you got nothing. Newer systems use semantic matching. Greenhouse, for example, says it uses embeddings so that a search for a software developer also returns people whose titles read "software engineer" or "web developer" (Greenhouse).

You can't know which approach a given employer uses. The safe move is to include the exact phrase from the posting at least once for each core skill, then write naturally everywhere else.

Frequency and placement#

Many checkers count how often a term appears in the job post and expect a similar emphasis on your resume. If "SQL" appears five times in the posting, the tool assumes it is central and may want to see it more than once.

Placement matters too. A skill that appears in your most recent role's bullets signals current use. The same skill buried in a 2014 job or only in a skills list reads as weaker evidence to a human, and some tools weight recency as well.

What checkers can't measure#

• Whether your claimed skill is true or backed by a result
• Whether your career story makes sense for the role
• How your resume compares with the other applicants in the pile
• Knockout answers you give in the application form
• Referrals, internal candidates, and recruiter judgment

That last list is why a high score never guarantees an interview, and a modest score doesn't rule one out.

How real applicant tracking systems rank candidates#

Employer-side ranking is common, but it is not universal and it is rarely a pure keyword count. Research by Harvard Business School and Accenture found that most employers using a recruiting management system rely on it to make a first cut or rank applicants, as summarized in HBS Working Knowledge.

The same study found that 88% of employers agreed qualified high-skilled candidates were screened out because they did not match the exact criteria in the job description, and 94% said so for middle-skilled candidates, as HR Dive reported. The lesson for you: exact criteria matter. If a posting asks for a credential or a specific tool, state it plainly.

Required qualifications carry the most weight#

Workday's HiredScore grades show how this works in practice. The grade depends first on basic (required) qualifications, then on preferred ones.

Source: Workday HiredScore candidate grades.

Notice what the table implies. Moving from C to B means covering every required qualification. Adding a fifth soft skill does nothing for that jump. This is why a checker score that rises because you added "team player" and "detail-oriented" is a hollow gain.

Recruiters still search and filter by hand#

Even when no ranking feature is turned on, recruiters search the candidate database by keyword, title, and location. If your resume says "client success lead" and the recruiter searches "account manager," you won't appear. Ranking and search both reward the same thing: the employer's own vocabulary, used accurately.

Some employers must disclose automated scoring#

In a few places, the law now requires transparency. New York City's Local Law 144 bars employers from using an automated employment decision tool unless it has had a bias audit within the past year, requires a summary of the audit to be public, and requires notice to candidates. The city's Department of Consumer and Worker Protection began enforcing it on July 5, 2023.

If you see a notice like that in an application, it tells you a scoring or ranking tool is in play. It doesn't change your strategy, but it confirms that clear, requirement-by-requirement evidence on your resume matters.

Knockout questions are the real auto-reject#

Answer those questions carefully and honestly. If you're unsure whether you qualify, read the requirement closely and contact the recruiter before applying. For a fuller list of what the software does and doesn't do, see our guide to common ATS myths.

What is a good ATS score?#

For most checkers, 75 to 80 out of 100 is a sensible target for a specific job post. The table below shows how to read each band and what to do next.

Why 75 to 80 is the common target#

Above that range, each added point usually comes from repeating terms or adding peripheral keywords. Those edits make the resume harder to read and rarely change how a recruiter or a qualification-based grade sees you. Below that range, you are usually missing something the employer stated as required.

When a lower score is fine#

A score in the high 60s can be perfectly competitive if:

• You meet every listed requirement, and the gap is mostly preferred skills or soft skills.
• The posting is long and lists dozens of tools, so no real candidate would match them all.
• You have a referral, and a person will review your resume regardless of rank.
• The role is niche, so the applicant pool is small and every resume gets read.

When you should aim higher#

Push toward 80 when the posting is for a popular role at a large employer, when you're changing careers and your past titles don't match, or when the job asks for a specific stack of tools. In those cases, a recruiter's keyword search is more likely to decide whether you're seen at all.

Why your ATS score is low: a diagnostic table#

Before you start rewriting, find the actual cause. Most low scores trace back to one of a handful of problems.

If the parsing preview looks broken, start there. Our guide to resume parsing errors walks through each failure and its fix, and the free ATS resume checker shows how your sections and dates come through.

How to improve your ATS score in 10 edits#

Work through these edits in order. The early ones fix problems that make every later edit worthless.

1. Fix parsing problems: single column, standard headings, contact details in the body.
2. Add a headline that uses the exact target job title.
3. Add required hard skills and tools you genuinely have.
4. Put each core keyword inside a bullet that proves it.
5. Spell out acronyms once, with the abbreviation in parentheses.
6. Match the posting's language for degrees, licenses, and certifications.
7. Rewrite your summary for this job, leading with the top two requirements.
8. Reorder your skills section so the posting's priorities come first.
9. Move the most relevant bullets to the top of each role.
10. Save in the requested file format and re-run the check.

Fix parsing before keywords#

If your job titles land in the wrong field, no amount of keyword work will help. Use standard section headings such as "Experience," "Education," and "Skills." Avoid text boxes, headers and footers for essential details, and graphics that hold words. If you are unsure which file type to send, read PDF or Word for your resume and follow the employer's instructions when they give any.

Mirror the target job title#

Title alignment is one of the cheapest gains. If you are a "Customer Success Specialist" applying for "Account Manager" roles, add a headline under your name that names the target role and the overlap. Don't change your actual past titles. Recruiters verify those.

Add missing hard skills you actually have#

Checkers often list skills you have used but never wrote down. Common examples are tools you use daily and stop noticing: Excel features, ticketing systems, CRMs, or regulatory frameworks. Go through the missing list line by line and ask one question: could I talk about this for two minutes in an interview? If yes, add it. If no, leave it out.

To pull a clean, ranked list of requirements from a posting, use the steps in how to find keywords in a job description or the free job description keyword finder.

Put keywords in context, not just in a list#

A skills section helps parsing and search. A bullet that shows the skill producing a result helps both the score and the human reader. Aim to place every must-have keyword in at least one bullet.

The after version adds "Tableau" and "SQL" as keywords, but it also gives a recruiter a reason to believe them. For more ways to attach numbers to your work, see how to quantify achievements on a resume.

Spell out acronyms once#

Write "Search Engine Optimization (SEO)" or "Electronic Health Records (EHR)" the first time. After that, use whichever form the posting uses most. This covers exact-match tools, semantic tools, and recruiters who search either version.

Match credential language#

If the post says "Bachelor's degree in Accounting or related field," write "Bachelor of Science in Accounting" rather than "B.S., Acct." If it asks for "PMP," write "Project Management Professional (PMP)." Required credentials are often the difference between a C and a B grade on qualification-based systems.

Rewrite the summary for this job#

Your summary is prime real estate. Lead with the target title, years of relevant experience, and the two requirements the posting stresses most.

The resume summary examples guide has more patterns by role and career stage.

Reorder your skills section for this posting#

Most people write a skills section once and never touch it again. Reordering it per application takes two minutes. Put the posting's required tools first, then preferred tools, then everything else. Group related items under short labels such as "Analytics," "Systems," or "Certifications" so a recruiter can scan them.

Keep the list honest and tight. Twelve to twenty items is plenty for most roles. Our guide to the skills section on a resume covers grouping and ordering in more depth.

Move the most relevant bullets to the top#

Within each role, recruiters read the first two or three bullets and skim the rest. Some ranking tools also weight earlier text more heavily. So if the posting is about vendor management and your vendor bullet sits fifth under your current job, move it to first.

You don't need to rewrite anything for this edit. You're changing emphasis, not facts, and it often raises both the score and the human read.

ATS score by resume section: where the points come from#

Each section of your resume contributes something different to the score. Knowing which section carries which signal helps you decide where to spend ten minutes of editing.

Headline and summary#

These sections carry title alignment and your top two or three keywords. Because they sit at the top, they also shape the recruiter's first impression in those few seconds of skimming. One precise headline and a three-line summary usually do more for a score than a page of extra bullets.

Skills section#

This is where exact-match tools find most of their hard-skill hits. It also feeds recruiter search filters. Its weakness is that it proves nothing on its own, which is why every critical skill should appear in a bullet too.

Experience bullets#

Bullets carry context and recency. A tool that weights recent roles will credit a keyword in your current job more than the same keyword in a role from eight years ago. Bullets are also the only place a recruiter sees results, so they decide whether a high score turns into a phone screen.

Education and certifications#

These sections answer yes-or-no requirements: a degree, a license, a certification. They're small, but missing them can drop a qualification-based grade by a full letter. Write the full credential name, the issuing body when it's relevant, and the date or expected date.

Career changers and the ATS score#

If you're changing fields, your past titles will rarely match, so title alignment and transferable hard skills carry more of the load. Use the headline to name the target role, lead the summary with the skills that transfer, and add a short projects or training section with relevant work. Expect your first scans to sit in the 50s and 60s, and judge progress by whether each required qualification is now visible rather than by the raw number.

Worked example: raising a sample resume from 54 to 81#

Say you're an operations coordinator with four years at a regional distributor, applying for a supply chain analyst role. The posting asks for SQL, Power BI, demand forecasting, inventory optimization, and a bachelor's degree, with APICS certification preferred. Your first scan returns 54.

Here's how a set of honest edits might move that number. The point values are illustrative, since every tool weights differently.

What the example teaches#

The biggest single jump came from adding real hard skills the candidate had never written down. The second biggest came from the parsing fix, which cost nothing but a template change. None of the gains came from soft skills or repetition.

Notice where the edits stopped. At 81, the remaining "missing" terms were things like "fast-paced," "self-starter," and a forecasting tool the candidate had never used. Adding those would push the number up and make the resume worse.

The bullet rewrite that did the most work#

That single bullet supplies three keywords, two metrics, and a story you can tell in an interview.

What the candidate chose not to add#

The checker still listed several "missing" terms at 81. Each was left out for a reason:

• "Fast-paced environment" and "self-starter": generic phrases that add nothing a bullet doesn't already show.
• A forecasting platform the candidate had never used: adding it would invite an interview question with no good answer.
• "Master's degree preferred": the candidate doesn't have one, and no keyword trick changes that.
• A second mention of "inventory optimization" in an older role: the term already appeared twice where it mattered.

That restraint is the difference between optimizing and gaming. The resume that results is one you can defend line by line in an interview.

When a higher ATS score stops helping#

There is a point where optimizing the score works against you. The resume still has to persuade a person, and recruiters skim fast. A 2018 eye-tracking study by Ladders found recruiters spent about 7.4 seconds on an initial resume screen, as HR Dive reported. The same study found simple layouts with clear headings held attention best.

Signs you've over-optimized#

• The summary reads like the posting's "About you" section with the pronouns changed.
• Your skills section has more than 25 items, half of which you've never used at work.
• The same keyword appears four or more times in one role.
• Bullets start with keywords instead of actions and results.
• You've added soft-skill adjectives that no bullet supports.

The 90-plus trap#

Scores above 90 usually come from mirroring the job description closely. Some tools reward that. People don't. If your score is in the 90s, read your resume aloud. If any sentence sounds like it was written by the employer, rewrite it in your own words with your own numbers.

Automation can miss good candidates#

Software ranking isn't perfect, and employers know it. In a 2022 SHRM survey, 19% of organizations using automation or AI in HR said those tools had accidentally overlooked or excluded qualified applicants or employees (SHRM). That's another reason to pair a solid score with a direct route to a person, such as a referral or a short note to the hiring manager.

Why ATS checkers disagree with each other#

If you run the same resume through three tools, you'll get three numbers. That's normal. The table below shows the most common reasons.

How to use more than one tool#

• Pick a primary tool and use it for every application so your numbers are comparable over time.
• Use a second tool only to confirm parsing, since parsing failures are the costliest problem.
• Ignore suggestions that conflict with the posting's own requirements.
• Track the score you applied with in your job application tracker, alongside response rates.

How often to rescore#

Rescore after every meaningful round of edits, not after every word change. A practical rhythm is three scans per application: one on your master resume to see the starting gap, one after you add skills and align the title, and one final check after proofreading. If the second and third scans differ by only a point or two, you're done.

Over 20 or 30 applications, you'll see whether higher scores lead to more callbacks for your field. That personal data beats any generic threshold. For a deeper look at how close is close enough, see how closely your resume should match the job description.

A 15-minute ATS score routine for every application#

Use this checklist before you hit submit. It assumes you already have a clean master resume.

• Copied the full posting, including requirements and preferred qualifications
• Ran the resume through a resume-to-job match checker and saved the starting score
• Checked the parsing preview for name, titles, employers, and dates
• Highlighted every required qualification and confirmed each appears in plain words
• Added the exact target title to the headline
• Added missing hard skills you can discuss confidently
• Placed each must-have keyword in at least one bullet with a result
• Spelled out key acronyms once
• Rewrote the summary's first sentence for this role
• Re-ran the check and stopped once the score hit the mid-70s or higher
• Read the resume aloud for stuffing or copied phrasing
• Saved with a clear filename, such as FirstName-LastName-Resume.pdf

If you want the tailoring steps in more detail, the guide to tailoring your resume in 30 minutes breaks each one down. The free resume to job description match tool compares your draft with a pasted posting and lists the gaps, which shortens the loop.

Next steps: use the score, then get back to applying#

An ATS score is a flashlight, not a finish line. Use it to catch parsing failures and missing requirements, push toward the mid-to-high 70s with honest edits, and then stop.

Here's what to do this week:

• Run your current resume against one real posting and note which required skills are missing.
• Fix any parsing problem the preview shows, then rescore.
• Build or update a master resume so tailoring takes 15 minutes, not two hours.
• Read up on resume keywords and ATS-friendly formatting to make your base version stronger for every future application.

The software decides whether you get seen. Your bullets decide whether you get called. Spend your time on both, in that order.
