All tools within a selection system should have incremental validity.$$

$$ If the bank includes both the Basic Skills Test and the Employment Inventory in its hiring system, will both tools have incremental validity? Explain your answer and support it with statistical evidence.$$

$$ A job knowledge test would have incremental validity if included as a third tool in the system. Use the internet to research different selection tool developers and identify an example of a job knowledge test that you would recommend to the bank. Identify the tool and the vendor that sells the tool. Describe why you would recommend this particular job knowledge test. In your explanation, justify your recommendation using information from the vendor$$s website about test content and its relevance to hiring for a bank position, cost and administrative ease, and criterion$-$related validity.$$
