The Grooved Pegboard Test is a manipulative dexterity test consisting of 25 holes with randomly positioned slots. Pegs with a key along one side must be rotated to match the hole before they can be inserted, requiring more complex visual-motor coordination than most pegboard tests.

The Grooved Pegboard is equipped with pegs, and examiner’s manual

This manipulative dexterity test contains twenty-five holes with randomly positioned slots and pegs which have a key along one side. Pegs must be rotated to match the hole before they can be inserted. This procedure measures performance speed in a fine motor task by examining both sides of the body, inferences may be drawn regarding possible lateral brain damage. The test requires more complete visual motor coordination than most of our pegboards and has been used in several neuropsychological test batteries, in student labs, and as a screening technique in industrial environment.
