The items to be considered when determining the need for simulation or some other method
of accomplishment in performance testing are summarized below.
Effect of task performance on the equipment readiness and
Potential damage to plant equipment and personnel.
Cost of using plant personnel, equipment, and materials.
If any limitations result in a change of content in an established test, management,
administrative, and instructional approval should be required for the change.
Determine Elements to be Tested
The elements of the task represent an important design consideration. The developer should
determine which elements can be tested realistically and should focus on elements that have
the greatest number of skill and knowledge statements. When limitations make performing
the task during the performance test unrealistic, task elements should be examined.
Elements that include important decision points are predictors of successful performance of
the task. If they can be tested realistically, they should be included in the performance test.
A critical task element (C) is defined as any element of the task that is deemed crucial to the
satisfactory performance of the task. Task elements such as removing interference,
obtaining the procedure, and cleaning the job site are typically non-critical task elements
(NC). Non-critical elements are generally administrative controls and tend to be generic to
other tasks. The critical/non-critical designation becomes important in the scoring and
evaluation criteria. To determine if an element of a task is critical, consider the following
guidelines. An element may be critical if its omission or improper execution:
Causes or could cause damage to any system or component to the extent that it
prevents the system or component from being immediately available for its
