The school district of wattville, delaware, is considering using the colorado achievement test (cat) this year. this test must be administered by a school psychologist to each student individually, with each student's testing time being about two hours. without knowing anything else about the cat, the wattville school district should probably question the test's:
a) practicality.
b) content validity.
c) standardization.
d) reliability.

The correct answer is a) Practicality.    

Explanation:

Practicality refers to the ease in which a psychological evaluation is administered.

When a large group of people is performing a psychometric test, it is essential to consider the practicality with which the test will be applied to optimize the time during and after the application.  

It is considered that the test has the appropriate practicality if it has accessibility at the time of the application and ease in the analysis and interpretation of the results to obtain the conclusions.  

For example, the Wattville, Delaware school district should consider whether it is practical to select a test that is individually applicable and will take a long time to apply to each student. Perhaps they should consider using a test that presents more practicality in its administration and analysis, as a test that is applied collectively.                

I hope this information can help you.
