Which one of the following is not a characteristic of a criterion test?

A criterion test is designed to judge a test-taker's performance against a fixed, predetermined standard or criterion, rather than by comparing test-takers against one another (as a norm-referenced test does). To serve this purpose well, educational-measurement theory holds that such a test must itself possess certain design qualities — appropriateness (fit between the test and the objective/criterion it targets), effectiveness (the test genuinely, validly, and reliably measures what it claims to, through appropriately discriminating items), and practicability (feasibility of constructing, administering, scoring, and interpreting it within available time and resources).

Among the given options, Appropriateness, Effectiveness, and Practicability are all established defining qualities of a criterion test. Brevity — simply being short — is not one of the recognised defining qualities: how long a criterion test needs to be is decided by how adequately it samples the criterion behaviour, not by minimising its length. So the option that is NOT a characteristic of a criterion test is Brevity.

• Appropriateness — a recognised characteristic; the test's content, format, and difficulty must fit the specific objective/criterion being measured.

• Brevity — not a recognised characteristic; test length is governed by adequate coverage of the criterion behaviour, not by shortness.

• Effectiveness — a recognised characteristic; the test must validly and reliably measure the intended criterion through well-constructed, appropriately discriminating items.

• Practicability — a recognised characteristic; the test must be feasible to construct, administer, score, and interpret within available time, cost, and resources.
