Which of the following is a COMPS subtest?

• A. Slow Movements
• B. Sustained Grip Strength
• C. Tandem Walking
• D. Visual Acuity

Answer: (A)

COMPS subtests isolate specific aspects of motor performance, and the one that examines how slowly and smoothly a child can execute deliberate, controlled movements is the appropriate item. This slow-movement assessment taps neuromotor control and motor planning, which are core for this battery. The other options measure different domains—grip strength looks at force production, tandem walking assesses balance and gait but not a distinct COMPS subtest, and visual acuity examines vision rather than motor execution. Therefore, the slow movements item best fits the COMPS subtest design.
