Which statement about reliability and validity threats in classroom vs workplace assessments is accurate?

• A. Reliability concerns are irrelevant to workplace assessments
• B. Threats include scoring bias; mitigation includes rubrics, rater training, calibration, and alignment with job tasks
• C. Reliability and validity cannot be improved
• D. Validity is more important than reliability in all contexts

Answer: (B)

The main idea is that threats to reliability and validity in assessments show up when scoring is inconsistent or when what’s being measured doesn’t match what matters for the job. In workplace assessments, scoring bias is a real worry because biased judgments can distort results and undermine both consistency (reliability) and accuracy (validity). The strongest remedy is to use explicit scoring rubrics that spell out the criteria for each performance level, train raters to apply those criteria, and regularly calibrate them so they interpret and apply the rubric in the same way. Pairing this with tasks that truly reflect job duties helps ensure the assessment measures what matters for performance, strengthening validity.

It’s not true that reliability doesn’t matter in workplace settings, or that both reliability and validity can’t be improved. And validity isn’t universally more important than reliability in all contexts; reliability underpins validity—without consistent measurement, a validity claim loses credibility.
