What is the maximum BD rotational error raw score?

The maximum BD (Block Design) rotational error raw score is 13 points. This score is determined based on the scoring guidelines outlined in the WISC-V manual, which assesses how well a child can manipulate blocks to recreate a specific pattern.

In the context of Block Design, a rotational error occurs when the child correctly positions the blocks in overall orientation but makes mistakes in their arrangement relative to rotation. Each correctly placed block contributes to the overall score, while errors have specific penalties attached. The standardization provided in the WISC-V ensures that any score derived aligns with established norms for cognitive assessment.

Understanding the significance of a rotational error score is vital for interpreting performance. A maximum score indicates the highest level of error attributable to this specific task, allowing for a better assessment of spatial visualization skills and problem-solving abilities in children.
