General Customer Experience & Contact Center FAQs
What Is Call Calibration in a Contact Center?
Last Updated September 28, 2026
Call calibration is a quality-management process in which multiple evaluators review the same customer interaction, score it using the same quality criteria and discuss differences. The purpose is to create consistent interpretation of the scorecard so agents are evaluated fairly and quality data can be trusted across the contact center.
How a call calibration session works
- Select a representative interaction.
- Have participants score it independently.
- Compare total scores and item-level differences.
- Discuss the evidence behind each rating.
- Clarify ambiguous criteria.
- Agree on the expected interpretation.
- Document scorecard or guidance changes.
Who should participate
- Quality analysts.
- Operations leaders.
- Training representatives.
- Compliance or policy experts where relevant.
What good calibration looks like
How often to calibrate
Calibration frequency depends on program size, scorecard complexity, evaluator turnover and the pace of operational change. New scorecards, policy changes and new evaluators typically require more frequent sessions.
Teams should also recalibrate when evaluator variance rises or agents report inconsistent feedback.
Calibration with AI quality management
AI can evaluate a much larger share of interactions, but automated criteria still need validation against human expectations. Quality teams can compare AI outputs with calibrated human evaluations and investigate categories where disagreement is high.
Important employee decisions should remain explainable and reviewable rather than relying on an opaque score.
Calibration metrics
- Evaluator agreement.
- Variance by scorecard item.
- Number of disputed criteria.
- Time to resolve disagreements.
- Change in scoring consistency after calibration.
- Agent appeals or quality disputes.
