What is the reverse rule for SI testing for children aged 8-16?

The correct approach for the reverse rule in Similarities (SI) testing, specifically for children aged 8-16, involves administering items in reverse order until perfect scores are achieved. This technique is beneficial for ensuring that the test captures a child's maximum capabilities, providing a clearer picture of their verbal reasoning skills.

By starting at higher difficulty items and moving backward, the evaluator can identify the point at which a child can articulate similarities effectively. Achieving perfect scores on these reversed items indicates that the child has a solid grasp of the underlying concepts being assessed. This method helps to determine the child's overall performance in a more nuanced manner, especially when evaluating their ability to comprehend and express abstract relationships between concepts.

Other approaches, such as randomizing item order or continuing with higher age group items regardless of performance, do not align with the structured methodology required for accurate assessment in WISC-V testing. Adjusting scoring criteria after each item does not facilitate a consistent evaluation of a child's ability and can lead to invalid results. Thus, administering items in reverse order until perfect scores are obtained is the most effective strategy for accurately assessing the child's verbal reasoning ability.
