Quizplus · Accepted Answer

The concept referred to in the question is validity, and the specific type of validity that assesses whether the items on a test cover all the knowledge or skills assumed to be part of the construct being measured is content validity. Therefore, choice A - validity; content validity - is the correct answer. Choice B is incorrect because construct validity refers to how well a test measures an abstract construct or concept, not whether it covers all the relevant knowledge or skills. Choice C is incorrect because reliability refers to the consistency of test scores over time or across raters, not whether a test measures what it is intended to measure. Choice D is incorrect because predictive validity refers to the ability of a test score to predict future performance, not whether a test covers all the relevant knowledge or skills.
