According to the PS guidelines, what does the reverse rule entail?

The reverse rule is an important aspect of test administration that is applied to certain subtests in the WISC-V. It allows examiners to gauge a child's understanding and capability more accurately by backtracking through the test items. According to this rule, the examiner should administer preceding items in reverse order until the child achieves perfect scores on two consecutive items.

This approach is beneficial because it helps determine the highest level of performance for the child without having them miss potentially solvable items simply because they were presented in a more difficult order. By identifying a consistent pattern of correct responses, the examiner gains valuable insights into the child’s cognitive abilities. The other options do not properly encapsulate the rule's purpose or methodology, emphasizing the importance of focused assessment rather than random or non-sequential testing strategies.
