About the programme
Course Overview
Left alone, most managers rate upward: disagreement feels harder to justify than a generous score, and ratings drift until nearly everyone sits in the top two categories. A calibration meeting exists to correct that drift, but only if it is chaired well; run badly, it becomes a negotiation between the most senior manager in the room. This course prepares HR professionals and people leaders to facilitate calibration sessions that stay evidence-based. It covers preparing a rating distribution and supporting evidence before the meeting, recognising recency, halo and leniency bias as they surface in real time, and using structured discussion techniques to move a manager from an impression to a specific, dated example. Participants practise placing employees on a nine-box grid where potential and performance are both discussed, handling a manager who defends an inflated rating on personality grounds, and closing a calibration session with ratings the organisation can defend if challenged. The course also addresses the ongoing debate around forced distribution and when it helps or damages trust in the process.

Decide when forced distribution supports fair calibration and when it distorts genuine performance differences.
Close a calibration meeting with ratings and rationale the organisation can defend if formally challenged.

01Preparing for a Credible Calibration Meeting
2 sessions · 8 points
Session 1Building the Evidence Base Before the Meeting
- Compile each manager's proposed ratings alongside the specific evidence used to justify them.
- Analyse the current rating distribution against prior cycles to identify where inflation is concentrated.
- Brief managers in advance on the evidence standard expected, reducing surprises during the meeting itself.
- Identify employees whose rating has moved sharply from the previous cycle for closer discussion.
Session 2Setting Ground Rules for a Fair Discussion
- Set explicit ground rules for calibration, including how disagreement will be raised and resolved.
- Agree the level of seniority and functional mix needed in the room for a credible calibration session.
- Clarify in advance whether the meeting can change ratings directly or only recommend changes.
- Prepare a neutral facilitator role separate from any manager whose team ratings are being discussed.
02Recognising and Naming Rating Bias in the Room
2 sessions · 8 points
Session 1Spotting Recency, Halo and Leniency Bias
- Identify recency bias when a rating rests heavily on the most recent weeks rather than the full period.
- Recognise halo and horn effects where one strong or weak trait colours the entire rating.
- Spot leniency bias in a manager who rates generously to avoid a difficult conversation with their team.
- Name a suspected bias in neutral language that invites reconsideration rather than defensiveness.
Session 2Moving Managers from Impression to Evidence
- Ask the follow-up questions that convert a vague impression into a specific, dated example of performance.
- Request comparable evidence when a manager rates one team member noticeably higher than similar peers.
- Handle a manager who cannot produce evidence for a proposed rating without publicly embarrassing them.
- Distinguish a genuinely exceptional contribution from a manager's general enthusiasm for a team member.
03Facilitating the Calibration Conversation
2 sessions · 8 points
Session 1Using the Nine-Box Grid and Structured Discussion
- Place employees on a nine-box grid that discusses performance and potential as separate dimensions.
- Facilitate disagreement about grid placement using evidence rather than relative seniority in the room.
- Keep a calibration discussion moving at a pace that covers every case without rushing complex ones.
- Summarise emerging patterns partway through a session so the group can adjust before the end.
Session 2Handling Difficult Calibration Dynamics
- Manage a senior manager who dominates calibration discussion and out-argues weaker voices in the room.
- Respond to a manager who threatens to lose a team member if their rating is not upheld.
- Address a pattern where one manager consistently rates their team higher than every peer manager.
- Keep protected characteristics and personal circumstances out of the rating discussion appropriately.
04Closing Ratings and Improving the Process Over Time
2 sessions · 8 points
Session 1Reaching and Recording Defensible Final Ratings
- Reach a final rating for each contested case with a documented rationale distinct from the original proposal.
- Communicate a calibration-adjusted rating to the line manager before it reaches the employee.
- Prepare managers to explain a calibration-adjusted rating to their employee without blaming the process.
- Record calibration decisions in enough detail to support a later grievance or query.
Session 2Deciding on Forced Distribution and Process Design
- Weigh the benefits and risks of forced distribution against the organisation's culture and trust levels.
- Redesign a rating scale or set of definitions that is contributing to persistent inflation.
- Evaluate whether calibration meetings are changing ratings meaningfully or simply endorsing manager proposals.
- Feed calibration findings into manager training so future ratings need less correction at source.
