I am not a lawyer, but I thought the defence was if you can show that the screening criteria correlated with on the job performance it is OK. No matter what you think of protected groups using a criteria that does not correlate with performance is not very smart anyway.

There may be some certification process you can go through to get a test approved, but mere job applicability isn't enough. For example, this firefighting test was found to violate the 4/5ths rule.

You'd have a hard time convincing me that doing well on it didn't correlate with being a better firefighter.
