A characteristic of a good test that guarantees that scoring bias is minimized is objectivity. An objective test is designed to measure specific skills or knowledge without being influenced by the opinions or biases of the test scorer. In practical terms, this means that answers are evaluated based on clear criteria or predetermined answers, allowing for consistent and fair scoring across different test-takers. When objectivity is emphasized, it helps ensure that all participants are assessed based on their actual performance rather than influenced by subjective interpretations of their responses, which can vary from one evaluator to another.

In contrast, while reliability refers to the consistency of test results over time, comprehensive indicates the breadth of content covered, and validity pertains to how well a test measures what it is intended to measure, none of these directly address the issue of scoring bias as effectively as objectivity does. Focused on eliminating personal bias, an objective approach ensures that every student's performance is judged solely on the merit of their responses.
