Finger Dexterity -- Examples of Average Dexterity -- How to Develop the Evidence

Earlier this week we looked at the descriptions of finger and manual dexterity as rated vocationally relevant factors described in the Revised Handbook for Analyzing Jobs.  Average, even with the definition of statement of 34th to 67th percentile, lacks clarity.  No matter, the RHAJ gives examples of average finger dexterity, Level 3.  Three of the eight examples have correlation to everyday activities.  

F-3:1 Feeds tungsten filament wire coils into machine that mounts them to sterns in electric light bulb:

Finger dexterity is required to grasp coils with tweezers and insert them into slotted plate of mounting machine; and to pick up and examine finished mounts as they emerge from machine.

Ask the claimant about the ability to use tweezers.  

 F-3:2 Takes dictation in shorthand and transcribes dictated materials, using typewriter:

Finger dexterity is required in forming shorthand symbols with pencil or pen and in depressing keys of typewriter.

Ask the claimant about the ability to write quickly with a pen or pencil on a pad of paper.  

 F-3:4 Cuts and styles hair, using clippers, comb, and scissors, and performs other personal services for patrons of barber shop:

Controlled movement of fingers is required to use clippers, scissors, and other barber tools when cutting and shaping hair.

Ask the claimant about the ability to use scissors.  

If the claimant cannot use tweezers, write a note quickly, or use a pair of scissors to cut on a line, then the person cannot perform activities that require average finger dexterity.  The evidence fits well within the defined vocational criteria and permits the examination of vocational expert that assumes below average dexterity.
