What Is Calibration?
Calibration, in an HR context, is the structured process of bringing managers together to review and discuss employee performance ratings across teams, ensuring ratings are applied consistently and fairly rather than reflecting individual managers' differing standards.
Why Calibration Matters
- Without calibration, one manager's 'meets expectations' might equal another manager's 'exceeds expectations,' creating unfair outcomes in ratings, bonuses, and promotions.
- Helps control the overall distribution of ratings across the organization to align with budget for merit increases and bonus pools.
- Surfaces inconsistent or biased rating patterns for coaching and correction before final ratings are communicated to employees.
How a Calibration Session Typically Works
- 1Managers submit initial, draft performance ratings for their direct reports
- 2A calibration meeting is convened, usually with managers from the same function or level, facilitated by HR
- 3Each manager presents and justifies ratings for team members, especially at the highest and lowest ends of the scale
- 4The group discusses and, where needed, adjusts ratings to ensure consistency
- 5Final, calibrated ratings are then communicated to employees
Best Practices for Effective Calibration
- Use specific, evidence-based examples (tying back to BARS or documented achievements) rather than general impressions
- Keep calibration groups small enough for meaningful discussion, typically 6-10 managers
- Train managers on common rating biases (leniency, recency, halo effect) before the session
