Which approach contributes to bias-free assessment?

• A. Use a single, high-stakes test
• B. Rely on subjective impressions
• C. Use clear criteria, multiple measures, and unbiased tasks
• D. Grade only based on attendance

Answer: (C)

Bias-free assessment focuses on fairness by reducing the influence of nonacademic factors and evaluating what students actually know and can do. The best approach combines clear, observable criteria, multiple sources of evidence, and tasks that are designed to be fair and free of bias. Clear criteria let everyone know exactly what success looks like and keep scoring aligned across students. Using multiple measures—like tests, projects, presentations, and portfolios—provides a fuller picture of ability and reduces the impact of any single task that might disadvantage some students. Unbiased tasks avoid language or contexts that could advantage certain groups, and scoring with rubrics or standardized procedures helps keep judgments consistent. Together, these elements strengthen fairness, validity, and reliability in assessment.

Relying on a single high-stakes test can introduce bias due to stress or unfamiliar formats; relying on subjective impressions invites personal biases; grading only by attendance doesn’t measure learning.
