To address this, clinicians utilize specific scoring procedures, such as those outlined in the WAIS-IV or WISC-V, which allow for "process scores." In some clinical contexts, a score may be calculated that disregards time bonuses, focusing purely on whether the participant could eventually construct the design correctly. This disentanglement of motor speed from perceptual reasoning is essential for a fair assessment, ensuring that a physical limitation is not misdiagnosed as an intellectual one.
Moderately reliable but with notable practical flaws block design test scoring

The transition from a physical performance to a final intelligence metric follows a structured path: not just trial-and-error.
Scored not just on correctness but on time bonuses (e.g., perfect score within a time limit) and process (e.g., self-correction). This rewards rapid visuospatial reasoning, not just trial-and-error.
