Independent audits of AI hiring tools
Hiring AI deserves a closer look.
Lingana brings psychology and assessment expertise to independent audits of AI-enabled hiring tools. We examine fairness, job relevance, and the evidence behind automated scores and recommendations, helping organizations understand how their tools perform and where action is needed.
“To be equal; to match; to measure against.”

Who we help
Vendors of automated hiring tools
Build evidence behind your product’s fairness, validity, and job relevance.
Employers
Understand how your hiring tools perform in your organization and where improvements are needed.
What we audit
Five areas that support fair, evidence-based decisions and help identify potential legal risks.
Fairness & bias
Differences in scores and selection outcomes across groups, including adverse impact and threshold effects.
Transparency
How outputs are explained, use is disclosed, and decisions are documented and reviewed.
Validity & job relevance
The evidence behind what the tool measures and how it relates to job requirements.
Psychological integrity
Alignment with professional testing standards in design, interpretation, and use.
Privacy & consent
How candidate data is handled, what candidates are told, and how consent is obtained.
Fairness is only part of the question. Bias testing shows whether outcomes differ across groups. Validity asks whether the tool is actually measuring something relevant to the job.

The seal
The Lingana Audited seal
The seal is a public record of an independent audit for a specific version of a hiring tool. It gives clients and stakeholders a clear way to confirm what was audited and when, helping them make decisions with greater confidence.
The hiring tool and the specific version covered by the audit.
The date the independent audit was completed.
A unique ID links the seal to its public verification record.
The seal is valid for 12 months and can be renewed through a new audit.
Why Lingana
Psychologists, not just data scientists.
We view hiring tools as assessments. Our team brings industrial-organizational psychology, research and statistical analysis to each audit. We do not build or sell the tools we audit, so our role is to examine the evidence and report clearly on what it shows and where limitations remain.
Tell us about your hiring tool.
We’ll discuss how it is used, the evidence available, and the scope of an independent audit.

Frequently asked questions
Answers about audit scope, timing, independence, findings, and the Lingana Audited seal.
Don’t see your question?
Ask us directlyWhat kinds of hiring tools do you audit?
We audit AI-enabled tools used to screen, assess, score, rank, match, or recommend candidates. This can include assessments, interview tools, sourcing and matching systems, and other automated hiring technologies. We confirm whether a tool is suitable for audit during scoping.
What does an audit examine?
The scope depends on the tool and how it is used. It may include fairness and adverse impact, validity and job relevance, scoring and thresholds, transparency, documentation, psychological integrity, privacy, and candidate communication.
Do you audit the technology or how it is used?
Both can matter. A tool’s design and supporting evidence are important, but outcomes can also depend on the roles, candidates, thresholds, and decisions involved in its use. We agree on the appropriate scope before the audit begins.
What information will you need from us?
Depending on the scope, we may review product and technical documentation, validation evidence, information about the hiring process, and de-identified data on scores or outcomes. We confirm the exact inputs before work begins and agree confidentiality and data-handling arrangements in advance.
What if the audit identifies a problem?
That is part of the purpose of an independent audit. We explain what the evidence shows, where limitations or risks remain, and what should be addressed. Recommendations may include gathering additional evidence, changing the tool or how it is used, or completing further review. Where a seal is part of the engagement, some findings may need to be addressed before it can be issued.
How long does an audit take?
Most audits take approximately three to four weeks. Timing depends on the size of the project, data readiness, and access to documentation. We confirm the expected timeline during scoping.
How much does an audit cost?
Fees depend on the tool, the number of roles or use cases, the available evidence and data, the jurisdictions involved, and the agreed deliverables. After an initial conversation, we provide a clear scope, fee, and timeline before work begins.
How do you keep your audits independent?
We do not build or sell hiring technology. Our role is to examine the evidence, report what we find, and recommend what should be addressed. Clients remain responsible for implementing changes, and our findings do not depend on future work.
Can one audit address requirements in several jurisdictions?
Often in part. Some analyses, such as comparisons of outcomes across groups, can inform several requirements. Documentation, notices, and publication requirements may differ by jurisdiction, so the engagement sets out which frameworks and deliverables are included.
What if demographic data is unavailable or held by our vendor?
That is common. During scoping, we establish what data exists, what a vendor can provide, and which analyses the available information can support. Where data is limited, the report clearly explains what we could and could not conclude.
We’re based outside the US. Could US requirements still affect us?
They can. Some requirements depend on where candidates are located, where a role is based, or how a tool is used rather than where the organization is headquartered. We work remotely with clients internationally and can help define an audit scope around the relevant markets. Whether a specific law applies is a legal question that should be confirmed with qualified counsel.
Is an audit the same as legal compliance?
No. An audit provides independent findings about the system, evidence, data, and use examined. It can support compliance and risk management, but it is not legal advice or a guarantee of compliance. Employers, agencies, and vendors retain their own legal responsibilities.
What does the Lingana Audited seal mean?
The seal confirms that a specific version of a hiring tool completed an independent Lingana audit. Its public record identifies what was audited and when. It does not mean that the tool is bias-free or guarantee compliance in every context. Each seal carries a unique ID that you can verify here.
