Product Details

The Bayley-III Motor Scale offers everything you need to assess motor development in one convenient package.


  • The Fine Motor Subtest assesses fine motor skills associated with prehension, perceptual-motor integration, motor planning, and motor speed. Visual tracking, reaching, object manipulation, and grasping are also measured.
  • The Gross Motor Subtest assesses the movement of the limbs and torso. Items assess static positioning, dynamic movement (including locomotion and coordination), balance, and motor planning.
