Calibration

Calibration in evaluations –performance reviews, talent matrices, etc.– helps ensure that the standards used for rating are balanced, creating a common and coherent language to communicate patterns.

Those responsible for the process must provide all evaluators with a framework on how to assess their employees. They will need to choose a scale, explain what each level means and distribute the scores. The calibration process will ensure consistency in employee evaluations.

Beyond defining a common scale, calibration also involves reviewing and comparing evaluations carried out by different managers to ensure that the criteria are applied consistently throughout the organization. In this way, subjectivity is reduced, potential biases are detected and each evaluator is prevented from using different standards when assessing people’s performance or potential.

In many cases, this process is carried out through calibration meetings, where leaders and HR professionals jointly analyze evaluation results, compare similar cases and align criteria before validating the final ratings.

Well-executed calibration not only improves the fairness and credibility of evaluations, but also enables stronger decision-making in areas such as talent management, succession planning, professional development or salary reviews.
