Use the O’Connor Tweezer Dexterity Test to measure manual dexterity speed for small hand tools, such as the forceps in the hands of the anatomist, or surgeon, or biological laboratory worker.   Before you invest the time and money to train a new employee, test your applicants for skills like:

• assembling of armatures
• miniature parts
• repair of clocks and watches
• rapid hand work in the filling of vials

This test provides the answers you need to make informed decisions.

This test measures the speed with which an employee using tweezers or some similar instrument is able to pick up pins or similar small items one at a time and place them in small holes on a board or other metal plate. It very much resembles the Finger Dexterity Test but since a finger eye-hand coordination is required in the Tweezer Dexterity Test, some employees can make good scores in the Finger Dexterity Test, but not in this test. A high score indicates manual aptitude for work involving precision and steadiness in the use of small hand tools, such as the forceps in the hands of the anatomist, or surgeon, or biological laboratory worker, or the tweezers in the hands of a watch repairer or stamp collector

The O’Connor Tweezer Dexterity Test consists of 5 7/8” W x 11 5/8” L board. Located in the upper half of the board is a pin well measuring 4 ¾” in diameter arranged in 10 rows of 10 holes each spaced ½” apart. Into these holes, the subject can insert one pin 1” long and 1/16” in diameter.  The test requires the use of tweezers in placing a single pin in each 1/16 inch diameter hole. A high score indicates manual aptitude for work involving the use of precision small tools. Includes 1 tweezer, 100 pins, and detailed examiner’s manual.
