Why is it important to calibrate evaluation criteria across learners?

• A. To speed up grading by using a single standard.
• B. To ensure fairness, reliability, and consistency in judging performance.
• C. To maximize subjectivity in grading.
• D. To compare learners against a moving target.

Answer: (B)

Calibrating evaluation criteria across learners ensures that everyone is measured against the same criteria and performance descriptors, which makes the assessment fair, reliable, and consistent. When evaluators share a common understanding of what each level of performance looks like and anchor scores to concrete examples, ratings reflect actual demonstrated abilities rather than individual judge biases. This improves consistency across different raters and assessments, and makes grades more defensible and comparable across learners and cohorts. It also helps track true progress over time rather than variations caused by different evaluators. It’s not about speeding up grading or making judgments more subjective; it’s about keeping standards stable and applied uniformly so everyone is judged by the same yardstick.
