How ATS resume scores work

The short answer

When a resume checker says your resume scores 72, that number comes from the checker. It is not read out of the employer’s applicant tracking system, and the vendors’ pages read for this guide do not claim it is. Each checker decides what to count and how to weigh it.

This guide sets out what each checker says its score measures, from its own pages. None of the checkers was used to write it, and no resume was scored for it. Where a vendor makes a claim about outcomes, the guide names it as that vendor’s claim.

Three kinds of score

The checkers fall into three groups, and knowing which one you are looking at explains most of the differences between them.

A match against one job description. You paste a posting and the checker compares your resume with it. The score is about fit for that job, and it changes with every posting.

A check of the resume on its own. The checker runs a list of tests on the resume itself: layout, structure, grammar, length, the presence of sections. The score is about the document, whatever job it goes to.

A band instead of a number. The checker tells you coverage is poor, fair or great rather than giving a percentage.

Several checkers combine the first two.

Checker by checker

Jobscan is the clearest example of a match score. Every scan returns a Match Report with a match rate out of 100 for that job and the gaps it found. Given the company name or the job URL, it also identifies the employer’s applicant tracking system and tailors its guidance to that system. Its free plan gives 5 scans a month. Its AI Optimize then suggests skills and alternative bullets for the posting, each one for you to accept or reject.

Resume Worded scores the resume itself. Score My Resume gives a score out of 100 with line-by-line feedback; the first review is free and you can re-upload for free. A separate Targeted Resume check compares the resume with a pasted job description and shows matched and missing keywords.

Resume.io runs 16 checks on a resume and, when you paste a job description, adds a match score for that role. The basic grader is free and asks for an e-mail address. Its page says high scores lead to more interviews and that a score of 90% doubles your chances. It gives no method for either claim.

Enhancv runs 27 checks on content, layout, grammar and keywords, and its ATS check and job match score compare the resume with a job ad and flag missing keywords.

Kickresume runs more than 20 weighted checks of formatting, design, typefaces, structure and content. It is the one checker read here that publishes a line: 75% and up counts as good. Its checker is on the paid plans.

Rezi breaks its Rezi Score down section by section, and pasting a job description shows the keywords the resume is missing.

Huntr combines keyword, qualifications and responsibilities matching against a job and rates coverage as poor, fair or great.

Teal shows the top five keywords of a job description on its free plan. Teal+ shows every keyword and a match score of the resume against the role.

Simplify has a keyword match panel that compares a resume with a job description, beside a broader Resume Score. Its help centre is the only source read here that states the limit outright: neither score predicts an employer’s decision.

What none of them shows

No checker’s page read for this guide explains its weights in full: how much a missing keyword costs against a two-column layout, or why one section matters more than another. And none shows how its score relates to what happens after you apply, whether an employer’s system or a recruiter puts your application near the top.

That gap matters for the question most people are asking, whether an employer’s system ranks resumes and how. The checker pages describe their own scores, not the employer’s software, so they cannot answer it. Treat any page that gives you a single “ATS score” as one vendor’s model of a strong resume.

What a good score means

There is no shared scale. Kickresume calls 75% good on its own checker. Resume.io claims 90% doubles your chances, with no method. Huntr’s “great” is a band, not a number. A 70 on one checker and an 85 on another may describe the same resume.

So use a score in two ways only:

1. Compare a checker with itself. Score, edit, score again with the same tool and the same posting. The change tells you whether the edit moved the resume toward what that checker counts.
2. Read the gaps, not the number. A list of missing keywords or failed checks is more useful than the total. Add a keyword only where it is true of your work; a checker cannot tell whether it is.

A different kind of match

Jobapplier scores jobs rather than checking a resume’s format. Each job in its own listings gets a score from 0 to 100 against your profile, from titles, skills, the years the posting asks for and the work model, with a one-line reason. Your resume gets a match from 0 to 10 against that posting’s skills, read by a model trained on job postings. It runs no layout or grammar checks, its pages do not say it scores a job description you paste in, and like the others it does not claim to know what an employer’s system decides.

Before you pay for a score

Most of these checkers give part of their score free: Jobscan’s 5 scans a month, Resume Worded’s first review, Resume.io’s basic grade, Teal’s top five keywords, Huntr’s basic match scoring. Use those first. If you pay, you are paying for more scans, the full list of gaps or AI rewrites, not for a number an employer will see.
