An article on Inc.com describes 10 tests (including cost from select vendors) that are, in their words, "extensively validated, highly respected."
The list includes several that I would also recommend folks consider, including the Watson-Glaser and Wonderlic for cognitive ability and the NEO, 16PF, HPI, and OPQ for personality. (By the way, if you're going to invent a test, make sure you consider the acronym; in fact you may want to come up with the acronym first)
But, as pointed out on EASI-HR blog you need to think carefully about the situation before running out and buying one. Do you have documentation showing the competency/KSA measured by the test is required for the job? What are you going to do about pass points? These are just some of the questions that need to be addressed.
By no means should that dissuade the use of tests. But like any other high-stakes purchasing decision, conduct a risk assessment and cost/benefit analysis before making the leap. And use resources like Buros test reviews to check out what the experts have to say.
