How to check your resume's ATS score for free (and what the score means)

An ATS score is not a grade that an employer's system gives you. Recruiters' systems mostly store and search resumes. The score you see on a checker is that tool's estimate of two things: whether your file can be read, and how well its words match one job post.

Used that way, it is a quick, useful check. Chasing 100 is a waste of time. Here is how to run one and what to do with the result.

What a checker measures

• Parsing: can the text be pulled out in the right order, with sections and dates recognised.
• Keyword match: how many of the job post's important skills and terms appear on your resume.
• Placement: whether those keywords sit in your experience bullets, or only in a skills list.
• Basics: contact details present, standard section headings, a sensible length.

Different checkers weight these differently, so the same resume can score 62 on one site and 78 on another. Compare scores from the same tool only, before and after your edits.

How to check your score in two minutes

1. Pick one real job post you want to apply for. A score without a job post only measures formatting.
2. Open the free ATS scanner and paste your resume text, or the text copied from your PDF.
3. Paste the full job post, including requirements.
4. Read the missing keywords list before you look at the number.

The Dossier scanner runs in your browser, so your resume is not uploaded or stored. It also treats common variants, such as JS and JavaScript, as the same skill.

Reading the result

Start with any parsing warnings. If the tool reports missing sections, jumbled order or unreadable text, fix those first. A perfect keyword match is worthless if the recruiter's system cannot read the file.

Then go through the missing keywords one at a time. Sort them into three piles:

• True and missing: you have the skill but never wrote it down. Add it to a bullet that shows it in use.
• True but worded differently: you wrote "client meetings" and the post says "stakeholder management". Use the post's phrase.
• Not true: leave it out. Note it, because a gap in a core skill tells you how strong a fit the job is.

Why scores differ between checkers

Each checker decides which words in a job post count as keywords, how much each one is worth, and how much formatting matters. One tool may count "communication" as a keyword and another may ignore it as filler. One may give credit for "JS" when the post says "JavaScript" and another may not. That is why your score can swing by twenty points between sites. Pick one tool, and use its missing-keyword list rather than its number to decide what to change.

A worked example

A marketing coordinator pastes her resume and a post for a Content Marketing Specialist. The first scan flags five missing terms: SEO, content calendar, HubSpot, editorial guidelines and A/B testing.

She has run the team content calendar for a year and wrote the blog style guide, so she adds a bullet: "Ran the content calendar for 3 writers and wrote the editorial guidelines the team still uses." She has written for SEO but never said so, so she adds "SEO" to a bullet about blog traffic. She used Mailchimp, not HubSpot, so she leaves HubSpot out. She has never run an A/B test, so that stays out too.

Her second scan shows two missing terms, both true gaps. She stops editing and applies. In the interview she can talk about every word on the page.

How often to check

Scan once for every job you care about, after you tailor the resume and before you submit. It takes two minutes, and it catches the one keyword you forgot to bring over from your master copy. For a batch of similar jobs, scan against the one with the longest requirements list. If your resume covers that post, it usually covers the shorter ones in the same cluster too.

Scan again whenever you change templates or editors. A new layout can break parsing even when the words are the same, and the copy-and-paste test catches it before a recruiter's system does.

Checking without a job post

Most checkers will score a resume on its own. That tells you whether the file parses and whether the basics are in place. It cannot tell you whether you match a job, since there is nothing to match against. Use a format-only check once when you build a new resume, then always scan against real posts after that.

What score to aim for

There is no pass mark that employers share. Treat the number as a progress bar for one application. If you start low and your edits move it up, you have closed real gaps. Once the missing list holds only skills you do not have, stop. Pushing the score higher from there means stuffing words you cannot back up.

Fixes that raise the score and help with humans

• Move keywords from the skills list into bullets with a result attached.
• Use the job post's exact title in your header if it honestly fits.
• Spell out acronyms once: Search Engine Optimisation (SEO).
• Switch to a one-column layout with standard headings: Experience, Education, Skills.
• Export as a text-based PDF, not a scan or an image.

Fixes to avoid

Pasting the job post in white text, repeating a keyword ten times, or adding a block of skills you lack might lift a checker's number. A recruiter who reads the resume will see through it, and many systems show the plain text, white text included. Each of these trades a small gain in a score for a clear loss in trust.
