The normal range for Visual-Motor Integration (VMI) standard scores is 90 or above.
VMI tests assess an individual's ability to coordinate visual information with motor movements, a critical skill for tasks like writing, drawing, and many daily activities. Raw scores from VMI assessments are typically converted into standardized scores to allow for easier interpretation and comparison across different individuals and age groups.
Understanding VMI Standard Scores
Standardized VMI scores are designed with a mean (average) of 100 and a standard deviation (SD) of 15. This statistical conversion helps to categorize an individual's performance relative to a normative sample. A score of 100 represents average performance, and scores are then interpreted based on how far they deviate from this mean.
Here’s a breakdown of how VMI standard scores are generally interpreted:
Standard Score Range | Interpretation |
---|---|
90 or above | Normal |
80 to 89 | Below Average |
70 to 79 | Low |
Below 70 | Very Low |
As indicated, a VMI standard score of 90 or higher is considered within the normal range, suggesting proficient visual-motor integration skills. Scores falling below this range may indicate areas where an individual could benefit from further assessment or support to enhance their visual-motor coordination abilities.
