Why Unstructured Interviews and Careful Psychometric Use Matter in Recruitment

Research shows that unstructured, informal interviews can often give a better picture of a candidate than many self-report psychometric tests—except for tests measuring ability. This is important: psychometric tests are useful, but they shouldn’t replace human judgment.

Psychometric Tests Need Expertise

Many psychometric assessments require trained professionals to administer and interpret them correctly. Using these tools without proper knowledge can lead to inaccurate conclusions. For many businesses, this expertise may not be available, making self-administered tests risky.

Legal Considerations: Reasonable Adjustments

A recent UK case highlighted that failing to offer alternative assessments when requested by a candidate can be considered discrimination. To avoid legal problems, always:

• Offer reasonable adjustments where necessary

• Seek advice on alternative ways to assess candidates fairly

Understanding the Limits of Standardised Testing

Psychometric tests often compare candidates against standard benchmarks. But not every candidate fits that benchmark. Neurodivergent candidates, for example, may underperform in some tests despite being highly capable.

It’s important to:

• Interpret test results in context

• Recognize different cognitive styles and approaches

• Make hiring decisions that consider a candidate’s full potential

Striking the Right Balance

Relying too heavily on psychometric or cognitive tests can be risky. To get the best results:

• Use tests as one part of a wider selection process

• Combine them with structured interviews and other assessments

• Allow for reasonable adjustments and alternatives

Recruitment should identify potential and fit, not just test scores. Thoughtful and inclusive use of psychometric assessments helps you hire fairly and reduce legal risk.
