Final answer:
Abel should consider whether the test actually predicts success on the job and look for a different screening tool if there is no evidence to support the test's validity.
Step-by-step explanation:
As Abel's HR recruiting liaison, my advice to him would be option B. It sounds like a good idea to use a test to evaluate candidates' Excel spreadsheet skills. However, the key question is whether the test actually predicts success on the job. Abel should ensure that the test has been validated and that there is evidence to show that high scores on the test correlate with good performance in using Excel spreadsheets. If there is no such evidence, he should consider using a different screening tool.
