Assessment centre design and delivery

Top candidate selection with an assessment centre

When hiring either in volume, or at pace, assessment centres can be incredibly valuable.

People Business designs and delivers bespoke assessment centres to help organisations make fairer, more informed recruitment decisions. We create realistic assessment exercises around the skills, behaviours and capabilities required for success in the role, combining methods such as interviews, group exercises, role plays, presentations, case studies and psychometric assessment.

From graduate and volume recruitment through to specialist and senior appointments, we can support the complete process, from defining assessment criteria and exercises, to facilitating, evaluating candidates and providing feedback.

We’ve worked with clients to run post-graduate and MBA assessment centres and have a honed approach that has helped them to whittle down large numbers of high-calibre candidates using a series of online and in-person assessments.

Designing an effective assessment centre requires careful planning to ensure it accurately evaluates candidates’ competencies, behaviours and potential. Our assessment centres are structured to incorporate multiple exercises, measuring candidates’ suitability through both directly applicable case studies and gamified scenarios, which assess more than just intellectual horsepower and proficiency in technical acumen.

We know how important it is that the assessment centre should emulate the experience of working with the organisation, and while it’s always our objective to put candidates through their paces it’s also critical that they have a good experience. Individuals perform at their best when they feel at ease so we aim to hit the right balance of comfort and rigour, facilitating the assessment centre in a way that gives applicants a taste of the culture and expectations, often including key business stakeholder in delivering the day.

How we design a successful, innovative assessment centre

While we work with stakeholders to design our assessment centres, we bear in mind the following key points.

  • Define objectives and competencies: The first step is to establish clear objectives for the assessment centre. We help organisations to identify the key competencies and behaviours that define success in the role, such as leadership, problem-solving, teamwork, or decision-making. These competencies should align with business needs and be measurable throughout the process.

  • Choosing the right assessment methods: A variety of assessment exercises should be selected to ensure a well-rounded evaluation. These may include:

    •  Online pre-sifting, including questioning and timed video questioning
    • Interviews (structured or competency-based) to assess experience, motivation, and situational judgment
    • Group exercises to evaluate teamwork, leadership, and interpersonal skills
    • Role-plays to measure problem-solving, communication, and decision-making under pressure
    • Case studies or presentations to test analytical thinking and the ability to synthesise information
    • Psychometric tests (e.g., cognitive ability or personality assessments) to provide additional insight into candidates’ strengths and weaknesses.
  • Structuring the assessment centre: An effective assessment centre should be well-organised, with clearly timed exercises, trained assessors, and standardised evaluation criteria. It is essential to balance individual and group activities to assess different aspects of candidates’ skills. Additionally, assessors should be trained to observe behaviours objectively and use standardised scoring systems to minimise bias.

  • Ensuring fairness and validity: To maintain fairness, assessment centres should use structured frameworks that provide all candidates with equal opportunities to demonstrate their abilities. This includes removing bias, ensuring assessors follow consistent criteria, and making accommodations for candidates with specific needs. The validity of the assessment centre should be tested by comparing outcomes with actual job performance.

  • Providing feedback and evaluation: A well-designed assessment centre does not end with candidate selection; it should also include constructive feedback. Providing participants with detailed feedback on their strengths and areas for development enhances the candidate experience and can support future development, even for those not selected. Organisations can also evaluate the effectiveness of their assessment centre by reviewing success rates, participant feedback, and alignment with business outcomes.

Frequently asked questions

How can People Business support an assessment centre?

People Business works with organisations to design and deliver bespoke assessment centres around the roles they are recruiting for. We can help define competencies, design exercises and case studies, incorporate psychometric or ability assessments, prepare scoring frameworks, support assessors, facilitate the assessment process and provide feedback and evaluation.

What is the difference between an assessment centre and an interview?

An interview primarily relies on candidates describing their experience and how they might respond to situations. An assessment centre allows employers to observe candidates completing practical exercises and responding to realistic situations. Combining different assessment methods can therefore provide a more rounded picture of capability, behaviour and potential.

How can assessment centres reduce bias in recruitment?

Assessment centres can support fairer and more objective recruitment by assessing every candidate against clearly defined criteria and using several sources of evidence. Structured exercises, trained assessors and standardised scoring also help reduce reliance on individual judgement or interview impressions.

What exercises can be included in an assessment centre?

Assessment centre exercises can include competency-based interviews, group exercises, role-plays, presentations, case studies, written exercises, psychometric assessments and cognitive or ability tests. The exercises should be selected according to the requirements of the role rather than using the same format for every recruitment campaign.

When should an organisation use an assessment centre?

Assessment centres are particularly useful when recruiting several candidates, making high-impact appointments or assessing roles where behaviours and interpersonal skills are important. They are commonly used for graduate recruitment, management and leadership recruitment, volume hiring and roles where employers need to distinguish between several strong candidates.

What is an assessment centre in recruitment?

An assessment centre is a structured recruitment method that uses several exercises to evaluate candidates against the skills, behaviours and competencies required for a role. Activities can include interviews, group exercises, role-plays, presentations, case studies, psychometric assessments and ability tests. Using several methods allows employers to gather a broader range of evidence than an interview alone.
