What does validity mean in the context of assessment?

In the context of assessment, validity refers to the extent to which a test measures what it claims to measure. When an assessment is valid, it means that results accurately reflect the students' understanding or mastery of a specific content area or skill. For instance, if a reading comprehension test is intended to evaluate students' ability to understand a text, a valid test will focus on this skill rather than incorporating unrelated content areas, such as mathematics or general knowledge. This focus ensures that the conclusions drawn from the test scores are meaningful and applicable to the objectives of the instruction.

Other options describe different aspects of assessment but do not pertain to the concept of validity. Some options may address reliability, practicality, or the diversity of assessment methods rather than whether the test accurately measures the intended construct. Recognizing these distinctions is crucial for educators in developing and selecting assessments that best reflect student learning outcomes.
