About the programme
Course Overview
An assessment centre is only as good as the exercises behind it and the assessors scoring them; a well-branded day with vague scoring produces decisions no more reliable than a gut-feel interview. This course teaches HR specialists and recruiters to design assessment centres that actually predict job performance. It covers translating a competency framework into in-tray, group and role-play exercises that generate real evidence, building behaviourally anchored scoring guides that different assessors interpret the same way, and training assessors to observe, record and score without letting first impressions or halo effects take over. Participants run a moderation or wash-up meeting the way it should work, reconciling different assessor scores against evidence rather than seniority. The course also covers checking a selection process for adverse impact against protected groups and adjusting exercises accordingly, plus managing candidate experience so a rigorous process does not feel punitive. Practice is built around designing a full exercise set and scoring guide for a real role and piloting it in a mock assessor panel.

Check a selection process for adverse impact against protected groups using appropriate analysis.
Design candidate communications and logistics that maintain a fair and positive assessment centre experience.
Evaluate an assessment centre's predictive value against later on-the-job performance data.

01From Competency Framework to Exercise Design
2 sessions · 8 points
Session 1Choosing Exercises That Generate Real Evidence
- Map each competency in the framework to the exercise type most likely to generate observable evidence.
- Design an in-tray or e-tray exercise that forces prioritisation under realistic time pressure.
- Build a group exercise brief that creates genuine interdependence rather than parallel individual work.
- Write a role-play brief and actor instructions that stay consistent across every candidate run.
Session 2Piloting and Refining Exercise Content
- Pilot a new exercise with internal volunteers to check timing, clarity and difficulty before live use.
- Remove content, references or assumptions from an exercise that could disadvantage a candidate group.
- Set pass marks and exercise weightings that reflect how critical each competency is to the role.
- Version and store exercise materials securely to prevent leakage between selection rounds.
02Building Behaviourally Anchored Scoring Guides
2 sessions · 8 points
Session 1Writing Scoring Guides Assessors Can Apply Consistently
- Write behavioural anchors at each score point that describe observable actions, not personality traits.
- Distinguish a strong, borderline and weak response for each competency with concrete example behaviour.
- Build a shared observation and note-taking template that separates fact from assessor interpretation.
- Test a draft scoring guide against recordings of previous candidates before rolling it out.
Session 2Training and Calibrating Assessors
- Train new assessors to observe and log behaviour throughout an exercise before forming any judgement.
- Run a calibration exercise where assessors score the same recorded candidate and discuss score gaps.
- Identify and correct common assessor errors, including halo effect, recency and similarity bias.
- Brief assessors on giving candidates accurate, professional feedback after the process concludes.
03Running the Assessment Centre and Moderation
2 sessions · 8 points
Session 1Managing the Assessment Centre Day
- Sequence exercises across an assessment centre day to manage candidate and assessor fatigue.
- Brief candidates so instructions are clear without giving an unintended advantage to confident candidates.
- Manage a candidate who under-performs early in the day without assessors carrying that impression forward.
- Handle a scheduling or technical disruption during the day without compromising exercise standardisation.
Session 2Chairing the Moderation and Wash-Up Meeting
- Chair a wash-up meeting that reconciles differing assessor scores against specific recorded evidence.
- Prevent seniority or force of personality from overriding documented evidence in a moderation discussion.
- Reach a final recommendation for each candidate that a rejected applicant's feedback can be traced back to.
- Record moderation decisions in enough detail to defend the process if a candidate raises a complaint.
04Fairness, Adverse Impact and Ongoing Evaluation
2 sessions · 8 points
Session 1Checking the Process for Adverse Impact
- Analyse selection rates by protected characteristic to check for adverse impact across a hiring round.
- Apply a recognised adverse impact test, such as the four-fifths rule, as a screening check rather than proof.
- Investigate which specific exercise or stage is driving an adverse impact finding before changing the whole process.
- Adjust exercise content or format to reduce unnecessary barriers without lowering the standard being assessed.
Session 2Evaluating and Improving the Assessment Centre Over Time
- Track assessment centre scores against later performance or probation outcomes to test predictive validity.
- Gather candidate feedback on process fairness and clarity without compromising exercise security.
- Retire or redesign an exercise that consistently fails to differentiate between candidates.
- Report assessment centre outcomes and fairness metrics to stakeholders in a concise annual review.
