Perf Calibration

Performance calibration

Calibration exists because a rating set by a single manager reflects that manager's standards, generosity, and blind spots as much as the employee's work. Putting managers in one room to defend ratings against a shared rubric surfaces the inconsistencies and the biases before anything reaches an employee. Done badly, it just hands the outcome to whoever argues hardest.

Method

1. Bring evidence, not adjectives. Each manager arrives with specific, dated examples tied to the rubric's dimensions: what was delivered, its scope, its impact. "She's a rock star" is not calibratable; "she owned the X launch at senior scope, with result Y" is. Rule out claims no one can check.
2. Anchor every rating to the rubric level. Read the written definition of each rating band and place people against it, not against each other's vibes. When two managers rate similar work differently, resolve it by returning to the anchor, so the standard is the rubric and not the room's mood.
3. Compare like work across managers. Line up people at the same level and ask whether a "meets" from one team would be a "meets" on another. This cross-manager comparison is the whole point: it catches the lenient grader and the harsh one and pulls both toward a common bar.
4. Run bias interrupts explicitly. Name the biases in the moment: recency (weighting the last month over the year), halo and horns (one trait coloring everything), and similar-to-me. Watch the language for patterns, such as warm competence words for one group and "abrasive" for another doing the same thing. Assign someone to call these out.
5. Give the facilitator authority. A neutral facilitator, often HR or a skip-level, keeps one loud manager from setting every rating, holds the group to evidence, and makes sure quiet managers' reports get equal airtime. Without that role, calibration rewards confidence over accuracy.
6. Record the rationale and close the loop. For every rating that moved, write down why, so the decision is auditable and the manager can deliver it with a straight story. Feed systematic gaps, such as a whole team rated low, into the next cycle instead of papering over them.

Signals

• Could you defend any rating in the room with dated evidence a peer manager accepted?
• Did at least one rating change because the group challenged it, or did every pre-meeting number survive untouched?
• Were the bias interrupts actually voiced, or only listed on a slide?

Boundaries

Calibration aligns ratings; it does not set the strategy of the underlying performance system, and it cannot rescue a rubric with no clear level definitions. Forced distributions, rating scales, and cadence are company conventions that shape how the meeting runs, so follow yours. The individual's evidence for advancement belongs to the promo-packet skill, and delivering the rating to the employee is a separate conversation.
