Which of the following statements about performance testing is NOT true?

The statement regarding performance testing that asserts it clearly defines the steps for each task is not accurate. Performance testing typically involves assessing individuals' abilities or competencies in a specific context, which may not always include explicit step-by-step instructions for how tasks should be performed. In many cases, performance testing is designed to evaluate candidates' problem-solving skills, adaptability, and instinctual reactions under pressure, rather than adhering to a rigid set of predefined steps.

The other statements about performance testing are aligned with its purpose. Diminished performance standards can refer to a leniency in evaluation criteria, while ensuring uniform standards for all candidates is vital for maintaining fairness in assessments. The elimination of guesswork for evaluators helps improve the consistency and reliability of evaluations, both of which are critical in successful performance testing environments. Overall, the expectation that performance testing will provide a clear and detailed guide for each task does not reflect its true nature.
