Answer 1

Answer:

C. C. The scoring is free from personal bias of the examiner.

Understanding Objectivity in Language Testing

• Objectivity in language testing refers to the extent to which the scoring process is free from the personal beliefs, attitudes, or biases of the examiner.
• It ensures that the test results accurately reflect the test-taker's ability, rather than being influenced by the scorer's subjective judgment or pre-conceived notions.
• A truly objective test should yield the same score for a particular performance, regardless of who is doing the scoring. This is often referred to as high inter-rater reliability.

• Methods to Ensure Objectivity:

  • Standardized Scoring Keys: For objective items like multiple-choice questions (MCQs), true/false, or matching, a pre-determined answer key ensures uniform scoring.
  • Detailed Rubrics: For more subjective tasks (e.g., essays, speaking tests), comprehensive and clearly defined scoring rubrics minimize examiner interpretation and bias by outlining specific criteria and score points.
  • Multiple Scorers: Employing more than one examiner to score a test, especially for high-stakes assessments, and then averaging their scores or resolving discrepancies, enhances objectivity.
  • Blind Scoring: Where possible, examiners are unaware of the test-taker's identity, background, or other personal details, which helps prevent unconscious bias.

• Why Objectivity is Crucial:

  • It contributes significantly to the reliability of a test, meaning the test consistently produces the same results under similar conditions.
  • It also supports the validity of a test, ensuring that the test measures what it intends to measure accurately and fairly.
  • Objectivity is paramount in high-stakes examinations (e.g., university entrance exams, certification tests) where fairness and accountability are critical.
• Contrast with Subjectivity: While objective tests aim for numerical, bias-free scoring, subjective tests (like essays or oral interviews) inherently involve more examiner judgment. However, even subjective tests can be made more objective through robust rubrics and training for examiners.
