SI Instruments - The Purdue Pegboard Test was first developed by Joseph Tiffin, Ph.D., an Industrial Psychologist at Purdue University in 1948.
The 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 complex visual-motor coordination than most pegboard tests.
The pegboards are supplied complete with pins, collars and washers and an examiner’s manual with norms.
