Tests can be used to facilitate some hiring decisions, but errors will always occur. This is because __________.

A) a standardized sample can never be found
B) norms vary from person to person
C) predictive validity is never 1.00
D) these tests are subjective

Predictive validity, which measures the accuracy of a test in predicting job performance or other relevant outcomes, is never perfect. Even the most successful tests have a certain margin of error, which means that some candidates who perform poorly on the test may still be a good fit for the position, while others who perform well may not be successful on the job. Therefore, hiring decisions based solely on test results may not always be accurate.
