Which term describes a test question with a definitive correct answer, not influenced by the scorer's opinion?

The term that accurately describes a test question with a definitive correct answer, independent of the scorer's personal opinion, is "Objective." Objective questions typically require a specific answer that can be verified and does not vary based on individual interpretation. This type of assessment is designed to measure knowledge or skills in a clear-cut way, allowing for uniform grading across different test-takers.

In contrast, subjective questions rely on personal judgment for scoring, which makes them inherently influenced by the biases of the evaluator. Constructive refers to a type of feedback or input rather than a style of questioning, while evaluative suggests an assessment process rather than the nature of the questions themselves. Therefore, "Objective" is the most appropriate term for test questions that have a clear and definitive answer.
