Explanation: The required qualities of reliability and validity are established for the express purpose of avoiding discrimination against protected classes. Answer choice A is incorrect because it makes no sense to ensure the same results from all tests - the tests would have no value at that point. Answer choice C is incorrect because the testing of candidates for a new position is about assessing the qualifications of the candidates and not quantifying the success rate of the company. Answer choice D is incorrect because it is too vague. Such guidelines would always be intended to create better standards for testing, but this is not specific enough to be a correct answer. And answer choice E is correct in the larger sense but is also not specific enough, since the standards were created for very specific reasons.
