Short answer: An AI resume screening score is as good as what it reads, and it reads the candidate's claims. In March 2026 the Dutch data protection authority reported that such scores can depend on a file format or a LinkedIn link. Before you rely on one, test its stability, ask what each input measures and keep a person reviewing every rejection.
This guide is for employers and staffing agencies that use or are buying CV screening software, not for candidates looking for a score checker. If your tool gives each applicant a score, a label or a pass or fail, ask three things: what is it built from, does it hold when nothing relevant changes, and who looks at the people it turns away?
Key takeaways
- The Dutch data protection authority (AP) says an applicant tracking system can reject candidates without anyone looking, and that a matching score can depend on a LinkedIn link or the file format (AP, 2026, p. 38).
- In its own test of an online assessment, the AP found that the employer could not trace how the tool reached a profile score of 53% (pp. 41 to 42).
- A score calculated from a CV still rests on what the candidate wrote. Software can add noise to a claim. It cannot turn a claim into evidence.
- A stability check on one fictitious CV takes about 10 minutes. It is good practice, not a legal requirement.
- Ask the supplier what each input serves, how stable the score is, and who reviews rejections.

What did the Dutch regulator find about AI resume screening?
It found weak transparency, and scores that can depend on irrelevant details.
In March 2026 the Autoriteit Persoonsgegevens (AP), the Dutch data protection authority, released the sixth edition of its Rapportage AI & Algoritmes Nederland, with a cover dated February 2026. Chapter 3, which starts on p. 35, follows recruitment step by step, from the vacancy text to the final choice.
Many applicant tracking systems now offer CV screening that analyses CVs for fit with the vacancy, the AP notes. The employer then sees the algorithm's selection, often with advice on whether to proceed, rather than every applicant. Such a system can reject candidates "without a person having looked" (p. 38, our translation), and the matching score can depend on technical criteria that may be insignificant or arbitrary, such as whether the CV contains a LinkedIn link, or its file format. The AP questions whether an organisation needs to use such a tool without human assessment (p. 38).
The same page describes applicants hiding transparent or white text in their CVs and cover letters, aimed at AI screening tools: a sign, in the AP's reading, that candidates increasingly write for the system rather than from their own experience (p. 38). A CV score can say as much about the document as about the person.
The AP's own test
The AP tested an online assessment for a fictitious sales manager role with three fictitious candidates (box 3.4, p. 42). Each candidate received a five page personal report that did not refer to the vacancy; one showed an above average score on cognitive skills. The employer received a 26 page report on that same candidate with a profile score of 53%, plus a ranking of all candidates. The candidate's above average result did not match the employer's conclusion, and the employer could not trace how the tool reached the profile score or how each part of the test contributed (pp. 41 to 42).
That was an online assessment, not a CV parser, but the problem is the same: a number without its reasoning. The AP's key messages say explainability and transparency in recruitment fall short on many points (p. 3). It says employers should weigh whether a tool is suitable and necessary, as some selection tools have no clear link with the job requirements, and that it will look at both providers and employers in 2026 (p. 44).
What the report does not show. It is a set of observations and one small test, not an enforcement decision, and it does not say how any named tool performs.
Why would a file format or a LinkedIn link change a score?
Because some tools react to how a CV is packaged, not only to what it says.
The research behind the AP's point is an audit by Rhea and colleagues (AP footnote 157 cites their 2022 conference paper; we use the extended journal version, Rhea et al., 2022). It examined two commercial personality prediction tools sold for hiring, using CVs and LinkedIn profiles from 94 graduate students at New York University, tested between November 2020 and September 2021.
- One tool gave some people markedly different personality scores for the same CV as a PDF or as raw text. For two people a trait score roughly doubled with the PDF; for two others it roughly halved (p. 19 of the open access version).
- The other tool was stable between PDF and Word, but its scores shifted substantially when a LinkedIn URL was added to the CV. The two versions were scored about four months apart, so timing may explain part of the change (p. 20).
The study measured personality scores, not CV matching or hiring decisions, for US graduate students rather than frontline applicants. Its value is the method: change something that should not matter and see whether the output moves. Two tools behaved very differently, which is why you test your own.
Two other findings point the same way. In a lab simulation of CV retrieval with text embedding models, across nine occupations and more than 500 CVs, the models significantly favoured white associated names in 85.1% of cases (Wilson and Caliskan, 2024); it tested embedding models in a simulation, not a commercial screening product. And in 2018 Reuters reported that Amazon had dropped an experimental CV rating tool, begun in 2014, which learned from ten years of mostly male applications and marked down CVs that included the word "women's" (Dastin, 2018). That account rested on five unnamed sources.
These studies do not prove that every screening tool fails. They do put the burden of proof on the tool. The researchers who revised the best known estimates of how well hiring methods predict performance wrote in 2023 that they were still waiting for a body of validity evidence to build up on newer predictors, such as gamified assessments and automated scoring of video interviews or essays (Sackett et al., 2023).
Why is a CV score still a claim?
Because the score is calculated from what the candidate wrote.
Radius Hire sorts the evidence behind a hiring decision into five kinds: verified (checked against a document or a third party), demonstrated (a task observed or tested), structured (the same question for every candidate, rated against criteria written in advance), claimed (the candidate's own statement) and not covered. Our Signal Gap article uses the same five levels to audit a whole hiring process; here we apply them to one tool output.
A CV sits at claimed. Parsing it, weighting it and turning it into a number does not move it up a level. The software can add influences the candidate never controlled: the file format, a profile link, patterns learned from past hires. A score moves up only when it rests on something stronger, such as structured answers about the job, a demonstrated task or a fact verified at the source.
This matters most in frontline hiring. When applicants for warehouse, cleaning, security or hospitality roles apply from a phone or through a job board, the format of their CV can depend on the device or the platform rather than on them. The requirements that decide whether someone can do the job, such as a valid certificate, night shifts or a 05:30 start, are often not on the CV at all. That is why we read a CV as a source of questions (We Hate CVs).

How do you test an AI resume screening tool in 10 minutes?
Score one CV in several versions and check whether the result moves.
Good practice, not a legal requirement. Radius Hire recommends this check. No law requires this specific test, and passing it does not show that a tool is fair, valid or lawful.
Before you start
- Use a test vacancy, in a test environment if your supplier offers one, so no real applicant is affected.
- Write one fictitious CV for that vacancy. Do not use a real applicant's CV: it would use their personal data for something they did not apply for.
- For each version, record what the tool gives (score, label or position) and the outcome (passed, held or screened out).
| Step | What you do | What it checks |
|---|---|---|
| 1 | Upload the CV as a PDF and record the result | Your baseline |
| 2 | Upload exactly the same PDF again | The same input should give the same result |
| 3 | Upload the same content as a Word file (.docx) | File format should not matter |
| 4 | Upload it as plain text, if the tool accepts it | File format again |
| 5 | Add one line with a profile link, upload, then remove it | A link adds no evidence about the job |
| 6 | Change one detail with no bearing on the job: a different name of similar length, a two column layout or the order of sections | Irrelevant details should not move the result |
| 7 | Put every result next to the baseline | Whether anything moved, and whether an outcome changed |
At about a minute per upload, the check takes around 10 minutes if your tool allows direct uploads.
Illustrative example: a worksheet for one fictitious CV. The values are invented to show how to record results and do not come from any real tool.
How to read your results
- An outcome changed (version D above): stop relying on automatic rejections. Send every candidate the tool would reject to a person until the supplier has explained and fixed the cause.
- Only the number moved (version E): ask the supplier what variation it treats as normal and where that is documented. The aim is no change between versions of the same CV.
- Nothing moved: good, but this is one CV and one vacancy. Repeat with a second CV, and after any model update or configuration change.
What the check cannot show. Whether the tool treats groups of candidates differently, which needs outcome data and often legal advice (see No Hiring Tool Removes Bias); whether the score predicts job performance; or whether its inputs serve any requirement, which the supplier questions cover.
What should you ask your CV screening software supplier?
Three things: what each input serves, how stable it is, and who reviews rejections.
1. Which written requirement does each input serve? Ask for every input the score uses, such as parsed fields, keywords, profile data or past hiring data, and the vacancy requirement each one relates to. Inputs that serve none, such as file type, layout or a profile link, should not affect the result. Without that list, you cannot explain to a candidate why the tool scored them as it did.
2. What stability testing have you done, and can we see it? Ask which variations were tested (format, layout, links, names, repeated runs), on how many CVs, with what results, and whether anyone independent checked.
3. What happens to a candidate the tool would screen out? Ask whether the tool can reject anyone without a person, and whether you can switch that off. Then set your own rule: a person with the authority and the time to disagree reviews every candidate the tool would screen out. Track the share of suggested rejections a person reviewed, and the share of those reviews that changed the outcome. A review that never changes anything may not be a real review.
For the wider buying decision, How to Choose AI Recruitment Software lists ten questions for any provider, and The Tool Should Never Be the One Saying No explains meaningful review.
What does this mean for staffing agencies and frontline employers?
Volume makes a score tempting, and it makes every error larger.
An agency screening for many clients runs one tool across many vacancies. If a score moves with file format, that error repeats on every role, and it falls hardest on candidates with the least control over how their CV was produced. Three habits help, for agencies and employers alike: write each client's or site's requirements down at intake, so every input can be tied to one; treat a missing answer as a reason for a call, not a rejection; and record, at the time, which requirement a candidate did not meet.
What does the law say about automated rejection?
Two EU laws are relevant, and how they apply depends on the facts.
Under the EU AI Act, AI systems intended to analyse and filter job applications or evaluate candidates are listed as high risk in Annex III (Regulation (EU) 2024/1689). The Act's rules for high risk AI in employment and recruitment apply from 2 December 2027, a date set by the Digital Omnibus on AI (Regulation (EU) 2026/1744), which moved it from 2 August 2026. Separately, the GDPR does not ban automated screening. It gives candidates the right not to be subject to a decision based solely on automated processing that significantly affects them, such as an automatic rejection, unless an exception applies: necessity for a contract, authorisation by law, or explicit consent (GDPR, Article 22). Where an employer relies on the contract or consent exception, candidates must at least be able to get human intervention, give their view and contest the decision; where a law authorises the decision, that law must lay down suitable safeguards. The AP adds that organisations can already be expected to meet requirements on explanation, transparency and meaningful human intervention, because these follow from the GDPR (p. 44). Whether a particular tool or configuration falls within these rules depends on how it is used, so take legal advice. Our guide to the EU AI Act and recruitment covers the dates and duties.

So, can you trust an AI resume screening score?
Trust it as far as you have tested it, and no further.
A score built from a CV is a summary of claims, and some tools add noise from how the CV is packaged. The Dutch regulator has now said so about tools used in the Netherlands. You do not need to abandon screening software to act on that: run the stability check this week, ask your supplier the three questions, and make sure a person reviews everyone the tool would turn away. Then put your effort where evidence comes from: structured questions about the job, demonstrated tasks and checks at the source.
How Radius helps
Radius Hire is the AI hiring platform for frontline roles. Candidates take a short, structured voice interview on their phone, whenever it suits them, and the recruiter sees the evidence behind each requirement.
- Match reads each interview against the requirements you wrote and shows the answer behind each one, with the moment in the interview that answered it.
- For each requirement, Radius shows whether it is backed by a document or a check, rests only on what the candidate said, or is still missing.
- Radius never rejects a candidate on its own. A recruiter reviews the evidence, can overrule anything Radius presents and makes every hiring decision (Trust and compliance).
- Where the employer uses Radius Passport, it checks identity and right to work with a trusted verification partner and records certificates with their expiry dates, so a recruiter can review the evidence before an offer.

FAQ
Do candidates have to be told that AI screens their CV?
Under the GDPR, candidates must be told how their data is processed: who processes it, why, on what legal basis, who receives it, how long it is kept and what their rights are. If solely automated decisions with significant effects are used, they must also get meaningful information about the logic involved and the likely consequences (GDPR, Articles 13 and 14). The AP also says organisations should inform applicants when AI is used in selection (p. 44).
What should we do if our tool fails the stability check?
Stop letting it screen anyone out without a person. Route every candidate it would reject to a recruiter, send your worksheet to the supplier, ask for an explanation and a fix, and run the check again afterwards. Keep a short record of what you found and changed.
How often should we repeat the check?
Whenever the tool or your configuration changes, and on a schedule you set. Triggers include a supplier model update, new vacancy templates, changed requirements or a new source of applicants. In the Rhea study, one tool did not give identical results even when the same CV was run twice in a row (p. 21), so keep the repeat upload in every round.
Can AI resume screening reduce bias?
Not reliably, on the evidence available today. Lab tests of language models used to retrieve CVs found strong preferences linked to names. If you use screening software, measure pass rates at each step of your process and act on what you find.
