Welcome to AI Situational Judgement Tests: Comparing the Leading Providers.

Comparing the Leading SJT Providers

Situational Judgement Tests assess how candidates make decisions in context. AI is increasingly used to score responses, generate scenarios, and scale SJTs across large populations.

Because SJTs blend judgement, values, and role context, AI can either enhance realism — or obscure what is actually being measured.

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

Key Psychometric Reality

AI can scale SJT scoring, but it cannot define “good judgement” without clear construct rules.
