Which statement best differentiates psychometrics from psychology ethics in assessment practice?

• A. Psychometrics concerns measurement properties of tests; ethics concerns professional conduct, decision-making, and client rights.
• B. Psychometrics covers therapy techniques; ethics covers test scoring.
• C. Psychometrics is legal compliance; ethics is statistical validity.
• D. Psychometrics and ethics are the same.

Answer: (A)

Understanding the distinction between the technical quality of tests and the ethical framework guiding their use is what this item targets. Psychometrics is about the measurement properties of tests—the reliability, validity, standardization, norms, and overall quality that determine whether test scores meaningfully reflect what they’re supposed to measure. Ethics in assessment practice governs how professionals conduct assessments, how decisions are made from results, and the rights of clients—such as informed consent, confidentiality, fairness, and culturally appropriate use. So the best statement is that psychometrics concerns measurement properties of tests; ethics concerns professional conduct, decision-making, and client rights. The other options misplace these elements or oversimplify their scope.
