Which of the following are the characteristics of a good test? A. Objectivity…

CONCEPT

A good educational test must yield defensible, useful evidence about learning. Its quality is judged not by one feature alone but by whether it measures the intended outcomes, samples the content adequately, scores consistently and objectively, identifies learning needs, and remains feasible to administer.

APPLICATION

• Objectivity limits scorer influence by using clear administration and scoring rules.

• Validity links the test evidence to the learning outcomes or construct it is intended to measure.

• Comprehensiveness provides adequate coverage of the relevant content and objectives.

• Diagnosticity helps locate strengths, weaknesses, and specific learning needs.

• Practicability keeps the test workable in time, cost, administration, scoring, and interpretation.

CROSS-CHECK / CONTRAST

• A, B, D and E covers scoring independence, construct alignment, diagnostic use, and feasibility, but leaves breadth of content coverage outside the set.

• B and D covers construct alignment and diagnosis, while leaving the scoring, coverage, and administration criteria outside the set.

• C and E covers breadth and feasibility, while leaving the scoring, construct-alignment, and diagnostic criteria outside the set.

Therefore all five statements—A, B, C, D and E—describe characteristics of a good test.
