Grooved Pegboard 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. This test requires more fine motor precision and complex visual-motor coordination than most pegboard tests. Some common uses are student labs, screening procedures in industry and evaluating lateralized brain damage. The pegs are conveniently stored under the nameplate.
