The extent which something is true.

The extent which something is true.

• A. Validity
• B. Reliability
• C. Organizational culture
• D. Plan of Correction

Answer: (A)

Validity is about how true a measurement is—that is, whether the instrument actually measures what it’s intended to measure. When a tool is valid, the evidence supports interpreting the scores as reflecting the real attribute or construct for the intended purpose. For example, a competency assessment meant to gauge clinical decision-making should require decisions in real patient situations; if it mainly tests memorization or unrelated skills, its validity is compromised because it isn’t truly measuring decision-making. Reliability concerns whether results are consistent across time or scorers, but a tool can be reliable without being valid if it keeps giving the same wrong result. The other options don’t fit because organizational culture relates to shared values within an organization, and a Plan of Correction is a remediation document, not a measure of truth.
