A weakness of using a performance-simulation test is that it is ____________.

Using a performance-simulation test can indeed present challenges, particularly regarding cost. The correct assertion is that these tests are typically expensive to create and administer. This expense arises due to several factors including the need for highly specialized resources to design realistic simulation scenarios that accurately reflect job tasks. Additionally, creating and maintaining these tests requires continuous updates and validation to ensure they remain relevant and effective, which further drives up costs.

Moreover, the time and effort invested in training assessors and setting up the testing environment contribute to the overall expense. While a well-designed performance-simulation test can offer valuable insights into a candidate's capabilities, the resources required to develop such tests can make them less feasible for some organizations, especially those with limited budgets.
