Which statement best describes reliability and validity threats in classroom vs workplace assessments and a mitigation?

• A. Use a single high-stakes test to maximize efficiency.
• B. Develop rubrics and provide rater training to improve scoring consistency and alignment with job tasks.
• C. Rely solely on self-assessments for accuracy.
• D. Assume all assessments are equally valid across contexts.

Answer: (B)

In classroom and workplace assessments, reliability and validity improve when you use clear, observable criteria and train evaluators to apply them consistently. Developing rubrics with detailed performance levels gives everyone the same expectations and reduces subjective judgments, which boosts reliability by ensuring scorers agree. Those same rubrics anchor what counts as good performance to actual job tasks or duties, strengthening validity because the assessment more accurately reflects what the job requires. Rater training calibrates judgments across different contexts, so outcomes mean the same thing whether the setting is a classroom or a workplace. By contrast, relying on a single high-stakes test can create more measurement error and narrow what’s assessed, self-assessments are prone to bias, and assuming validity is identical across contexts ignores how different settings can change what counts as valid evidence.
