Final answer:
A standardized assessment must be administered and scored consistently every time, ensuring reliability and comparability of results. The correct answer is option A. It is also essential for standardized tests to be normed, where they are tested on a representative sample.
Step-by-step explanation:
A standardized assessment is one that must be administered and scored in exactly the same manner every time. This standardization method of testing ensures that administration, scoring, and interpretation of results are consistent across all instances of the test. The purpose is to establish a common ground so that the outcomes are reliable and comparable. Therefore, the correct answer to the question is A.
Moreover, it is essential for a standardized test to be normed, which means it must be tested on a representative sample to collect data for comparing different groups. This process helps in creating norms or reference scores to interpret future test scores effectively. Thus, ensuring that a test is both normed and standardized is crucial for achieving reliable and interpretable results.
