What is a likely consequence of not standardizing testing protocols when applying normative data?

• A. Scores may not reflect the same conditions as the normative data, reducing comparability.
• B. Scores will be more accurate.
• C. Normative data will adjust automatically.
• D. Testing will be faster.

Answer: (B)

Standardization ensures that testing conditions, procedures, and scoring match those used to create the normative data. When those protocols aren’t standardized, the environment and administration may differ from the norms, so a score doesn’t reflect the same conditions. This makes the score less comparable to the norm and weakens the validity of the interpretation. The other ideas don’t hold because accuracy isn’t automatically improved without consistent procedures, normative data don’t adjust on their own to different testing conditions, and testing speed can vary without standardization rather than reliably increasing.
