Diversity and inclusion have moved firmly up the corporate agenda — and for good reason. Organisations with diverse teams make better decisions, are more innovative, and better reflect the customers and communities they serve. Yet progress in many organisations remains slow. One underutilised lever? Assessments.
The problem with traditional selection
Traditional selection processes — relying heavily on CVs, unstructured interviews, and network-based referrals — are riddled with opportunities for bias. We favour candidates who look like us, who went to the same universities, who communicate in the same style. This systematically disadvantages talented people from underrepresented groups.
How assessments reduce bias
Well-designed assessments provide objective, standardised data on candidates' abilities, personality, and potential — independent of their background, appearance, or communication style. When used properly, they can significantly reduce the impact of unconscious bias on hiring decisions.
Specifically, assessments can help by:
- Evaluating candidates on job-relevant competencies rather than proxies like educational pedigree
- Providing consistent, comparable data across all candidates
- Reducing the influence of gut feel and first impressions
- Identifying potential in candidates who might be overlooked by traditional screening methods
Important caveats
It is important to note that not all assessments are equally fair. Some cognitive tests, in particular, can produce differential results across demographic groups — not because of genuine differences in ability, but because of differences in test familiarity, cultural context, or language. This is known as adverse impact.
Responsible use of assessments for diversity means:
- Choosing assessments that have been tested for adverse impact and validated across diverse populations
- Using assessments as one input among many, not as a single deciding factor
- Regularly reviewing assessment data for patterns that might indicate bias
- Being transparent with candidates about how assessments are used
Game-based assessments: a more equitable approach
Game-based assessments have shown particular promise in reducing adverse impact. Because they present novel tasks that are unfamiliar to everyone, they tend to be less susceptible to the kind of prior exposure effects that can disadvantage candidates from less privileged educational backgrounds.
Conclusion
Assessments, used thoughtfully and responsibly, are one of the most powerful tools available for building a fairer, more diverse hiring process. The key is choosing the right assessments, using them in the right way, and continuously monitoring their impact.
