What is an ATS CV checker?
An applicant tracking system (ATS) is the recruitment software that receives your application when you apply through an employer's careers page, a job board or a recruitment agency. It opens your CV, picks out your name, email, mobile number, job titles, dates, skills and qualifications, and saves them as a candidate record that recruiters can search and filter. All of this happens before anyone reads your CV.
An ATS CV checker runs that same reading on your CV before you send it. It shows what the software would capture, what it would miss, and how closely your CV matches the wording of the job advert, so you can fix problems while there's still time. Think of it as a free CV review by machine, focused on one question: will a recruiter be able to find you?
How an applicant tracking system reads your CV
Despite what you may have heard, most ATS software doesn't "bin" CVs on its own. It makes them searchable, and the search is the real filter. A CV that's captured badly leaves a patchy candidate record, and a patchy record doesn't come up when a recruiter searches for "payroll administrator", "Sage" or "CIPD". Your application is there, but nobody finds it, which is one of the most common reasons good candidates never hear back.
- Receiving: your CV arrives through the online form, a job board or an agency.
- Parsing: the software converts the file into data, field by field.
- Searching: recruiters filter the database by job title, keyword, experience, location or screening questions.
- Shortlisting: only the candidates who come up in that search are opened and read.
Recruitment agencies work the same way: your CV goes into their database, and consultants search it each time a client sends a new vacancy. A CV that parses cleanly keeps turning up long after you sent it.
How the Kandiq ATS CV checker works
The ATS CV checker reads your CV as an applicant tracking system would: it extracts the text, rebuilds your sections, dates and skills, then applies 12 ATS checks. You get one ATS score out of 100 that brings together ATS readability, the content of your CV and, when you name a role or paste an advert, how well you match it.
- Automated reading: the text is recovered in the order an ATS would follow. A sidebar that ends up in the middle of your work history is spotted straight away.
- Structure: headings, dates and contact details are looked for where a parser expects them.
- Content: your job title, skills and keywords are compared with the role you're after.
- Score: every point lost is explained, with the fix that wins it back and how many points are left to reach green.
No AI model decides the score. It's calculated by fixed, weighted rules, so the same file always gets the same result. That's what lets you measure the effect of each change and check again as often as you like.
The 12 checks behind your ATS score
| Check | What the ATS checker looks at |
|---|---|
| Contact details can be extracted | Full name, email address and mobile number written out as text, under your name. |
| Job title at the top of the CV | The title of the role you want under your name: it's the first field the ATS indexes. |
| Recognised section headings | "Work Experience", "Education" and "Skills" are recognised; "My Journey" isn't. |
| Single-column reading order | Older parsers read line by line, so a sidebar can get mixed into your main text. |
| Dates in month/year format | A role with no start date is left out of filters such as "3+ years' experience". |
| Skills spelled out | Tools and skills written as words, the way adverts in your field write them, not as bars. |
| Keywords from the target job | How much of the advert's vocabulary your CV contains, once you paste it. |
| No decorative characters | Emoji, arrows and icons come out blank and can cut off the next sentence. |
| Readable font size and margins | Below 9 pt, extraction merges neighbouring lines. |
| No photo | An image in the header confuses some parsers, and a photo isn't usual on a UK CV. |
| One to two pages | Two pages is the UK norm; beyond that, many systems only index the start. |
| Real text PDF | A scanned PDF is just an image: the ATS has nothing to read. |
These checks are part of the AI CV checker, which also reviews the substance of your CV: what the hiring manager reads once the system has found you.
What's a good ATS score for a CV?
A good ATS score is one where you don't lose a single critical check: contact details captured, real text, complete dates. Those are the checks that leave your candidate record empty. Next come the content checks (job title, skills, the advert's vocabulary), which decide whether you appear in recruiters' searches. The report tells you how many points you need to reach green, and which fixes to make first.
- Contact details incomplete: write your full email address and mobile number as text, not as an icon on its own.
- Two columns detected: choose a single-column template, or test another design.
- Dates missing: add the start month and year, and the end date, to every role.
- Few keywords from the advert: use the terms that genuinely describe your experience.
- More than two pages: cut roles older than ten years and bullet points with no result.
Why a CV fails an ATS check
- A two-column template from a design tool: attractive on screen, read in the wrong order.
- Skill bars or star ratings with no words beside them: the software only sees shapes.
- Creative headings ("About Me", "My Story") that the ATS can't file anywhere.
- Text inside an image, often the top of the page with your name and number: the record comes out blank.
- A scanned CV or a photo of a printout: there's no text left to extract.
- Tables used for layout: some cells are read out of order, or dropped.
- Abbreviations on their own ("mgmt", "admin"): recruiters search for the full word.
How to write an ATS-friendly CV
- Choose a simple template: one column, clear headings, a readable font. Graphics add nothing for an ATS. Our CV templates flag the ones that pass every ATS check.
- Put the job title under your name, worded as the adverts word it.
- Open with a short personal statement: three or four lines on who you are and what you're looking for. See our guide to the CV personal statement.
- List your work experience in reverse chronological order, with the month and year for each role.
- Write your skills as words: software, qualifications, languages, licences. Our guide to skills for a CV has lists by sector.
- Export a PDF from your editor, never a scan.
- Run the ATS CV checker, fix what it finds, and check again before you apply.

Keywords: match your CV to the job advert
Recruiters search their ATS using the words from their own advert. Paste the advert you're targeting (its link, or its text if the site needs you to log in): the ATS checker compares your CV term by term and lists what's missing. Only add what's true, because a keyword you can't back up won't survive the interview.
The advert asks for: "stakeholder management", "Excel", "customer service".
On the CV: "Managed stakeholder updates for a £1.2m office move and built the weekly Excel tracker; led a customer service team of 5."
Kandiq can also tailor your CV to an advert with AI: it suggests new wording, and you keep only what's accurate. Tailoring uses 5 AI credits, and a new account starts with 5.
PDF or Word: which does an ATS checker prefer?
Both work, provided the text is real text. A PDF keeps your layout the same on every computer; recruitment agencies sometimes ask for Word so they can reformat your CV before sending it to a client. Send what the advert asks for and, if it doesn't say, a PDF exported from your editor.
| Exported PDF | Word (.docx) | Scanned PDF or image | |
|---|---|---|---|
| Read by an ATS | Yes | Yes | No |
| Keeps your layout | Yes | Not always | Yes, but unreadable |
| Editable by a recruiter | No | Yes | No |
Photo, date of birth and the UK CV
A UK CV doesn't include a photo, a date of birth, nationality or marital status. Age, race, sex, marriage and civil partnership are among the protected characteristics of the Equality Act 2010, and employers would rather not see information they can't base a decision on. A photo in the header also trips up some parsers, so the ATS checker flags it.
Your photo belongs on LinkedIn, which recruiters often open after reading your CV: see our LinkedIn profile picture tool.
When the employer uses an application form
Some employers ask you to complete an online application form instead of, or as well as, uploading a CV, with questions about your experience and supporting statements. The ATS CV checker reads CVs, not those forms. The same rules still help, though: use the words of the advert, give dates, and write out your skills and qualifications in full.
ATS and AI screening: what changes for you
Applicant tracking systems are adding more AI: automatic ranking, profile summaries, chatbot screening. For you, the difference is small. AI screening still needs a CV whose text extracts cleanly and that uses the vocabulary of the role. No AI can find experience that isn't written down.
At the end, a person still decides, after reading your CV and often your LinkedIn profile. Look after both: the ATS counts matches, the hiring manager looks for reasons to invite you in.

He also knows the candidate's side: internships, work-study, student jobs, a permanent contract, starting an agency, then freelancing. He built Kandiq to give candidates what he looked for in an application himself, and what screening software can read. His guides start from the questions candidates ask Google, rely on official public sources (government employment and careers services, employment law) and are updated when the rules change.
