Building Better AI Psychometric Tests (Without Breaking the Science)

Generative AI is already being used to write job descriptions, interview questions, and assessment content. But many HR leaders are asking a more cautious question:

Can AI improve psychometric test development without undermining validity?

A recent research paper that has gained strong engagement on LinkedIn argues that the answer is yes – if AI is used correctly.

How can Rob Williams Assessment help?

AI works best when it is paired with robust psychometrics. That means clear constructs, credible evidence, and defensible decision rules. Rob Williams Assessment supports organisations with:

  • Technical psychometric manual checking or creation: currently working on two of these for clients. We’ve previously created SJT and IRT-based aptitude manuals for the Civil Service, SJT personality and ability tests for the Army, and verbal/numerical reasoning and literacy/numeracy test manuals for IBM Kenexa.
  • Reviewing the potential application of AI within your organisation? A short, evidence-led review can clarify where AI adds insight — and where traditional expert judgement remains essential.
  • Assessment strategy: simulations, SJTs, and psychometric tools that provide stronger evidence than profiles alone
  • Vendor evaluation: independent due diligence on claims, outputs, and fairness
  • Validation and reliability checks, or new research

The Problem with Traditional Test Development

High-quality psychometric development is slow and expensive. Item writing requires:

  • Subject matter experts
  • Multiple review cycles
  • Pilot testing and refinement

This creates pressure to cut corners – particularly in high-volume hiring contexts.

Where AI Actually Adds Value

The research makes a critical distinction between item generation and measurement judgment.

AI excels at:

  • Generating large volumes of draft items
  • Creating parallel item forms
  • Reducing development time and cost

But it should not be responsible for:

  • Construct definition
  • Validity decisions
  • Score interpretation

Want a sanity-check before you buy?


I can review your use case, vendor claims, validation, fairness and other psychometric evidence and give you a clear go / no-go recommendation.

Book a vendor review (or start with a short discovery call).

Rob Williams Assessment Ltd supports organisations with AI vendor selection, and best practice psychometric test design and assessment strategy. If you want a short, practical review of your current approach, build a one-page brief outlining your use case, and we can stress-test it for you.


AI as an Assistant, Not an Assessor

The most important insight for HR leaders is this:

AI should support psychometricians, not replace them.

Used properly, AI increases efficiency while preserving scientific standards. Used poorly, it floods organisations with content that looks sophisticated but measures nothing reliably.

Why This Matters Commercially

Organisations adopting AI-assisted test development reported:

  • Lower development costs
  • Faster iteration cycles
  • Improved content diversity

Crucially, these gains were only realised when AI outputs were embedded within a rigorous psychometric workflow.

The Risk of “AI-Washed” Assessments

The paper warns against what many HR leaders are already seeing: AI-generated assessments with no evidence base.

These tools create:

  • False confidence
  • Legal exposure
  • Poor hiring decisions

What HR Leaders Should Do Next

If your organisation is using – or considering – AI in assessment design, the question is not “Is it innovative?”

The question is:

Is it psychometrically defensible?

AI can transform assessment quality, but only in the hands of organisations that understand measurement.
