: In order to be useful,a test must be reliable. I nother words, it must:
A.) produce the same results from one time to the next
B.) predict other criteria of the trait being measured
C.) measure what it is designed to measure
D.) Compare results against established standards of performance
i think it is D , but unsure...
No.

i am going with A
I agree.
Thanks Ms.Sue
To determine the correct answer, let's break down the options:
A.) Produce the same results from one time to the next: This refers to the test's reliability. A reliable test should consistently produce similar results when administered to the same individual at different times.
B.) Predict other criteria of the trait being measured: This refers to the test's validity. A valid test should accurately measure what it is designed to measure, and it should also be able to predict or correlate with other related criteria that are associated with the trait being measured.
C.) Measure what it is designed to measure: This also refers to the test's validity. A valid test should accurately measure the specific construct or trait it is intended to assess.
D.) Compare results against established standards of performance: This refers to the test's standardization. Standardization involves comparing an individual's results to established norms or criteria in order to interpret their performance objectively.
Now, let's examine the options:
A. Reliability is important for a test to be useful, as consistent results are crucial for accurate assessment. However, it is not the only requirement for a test to be reliable.
B. Although predicting other criteria is desirable for a test to be valid, it is not necessarily a requirement for a test to be reliable.
C. Measuring what the test is designed to measure is certainly important for a test to be valid. However, it is not the only requirement for a test to be reliable.
D. Comparing results against established standards of performance is related to standardization, an essential aspect of ensuring test validity. Standardization allows for meaningful comparison and interpretation of individual test scores.
Based on the provided options and the explanation above, the correct answer is D.) Compare results against established standards of performance.
