A practical clinical reference for pediatric OTs addressing visual motor integration — covering the developmental progression, assessment considerations, sample goals, grading strategies, caregiver coaching, and documentation language.
Understands basic maze logic. Matches simple shapes. Follows wide paths. Copies 2-colour AB patterns. Typically ages 3–4.
Navigates tighter corridors. Follows 8–10 dot sequences. Copies 3-colour ABC patterns. Notices subtle differences. Typically ages 4–5.
Stays within narrow corridors accurately. Copies multi-line designs. Extends patterns. Self-monitors errors. Typically ages 5–6.
Handles complex multi-step designs. Plans before acting. Manages spatial rotation and mirror tasks. Self-corrects independently. Typically ages 6–7+.
| Variable | Grade Down (easier) | Grade Up (harder) |
|---|---|---|
| Maze corridor width | Wide corridors (1 inch+) — lots of room for error | Narrow corridors (¼ inch) — demands high precision |
| Dot-to-dot sequence | 5–6 dots, simple shape — short sequence, easy to track | 15+ dots, complex shape — long sequence, high working memory demand |
| Pattern complexity | AB pattern (2 items) — minimal memory load | ABCDE pattern (5 items) + extension question — maximum load |
| Model distance | Model directly beside the copy space — look and reproduce immediately | Model on a whiteboard across the room — requires visual memory |
| Design complexity | 1–2 line design — single visual element to reproduce | 5+ element multi-component scene — spatial planning required |
| Self-monitoring demand | Therapist checks accuracy after each step | Child checks own work against model independently throughout |
| Time pressure | No time limit — child sets their own pace | Timed task — adds processing speed and efficiency demand |
| Cognitive load | One task at a time — maze OR copying, not both | Combined task — maze then copy the shape from memory |
