Test Scoring

Another type of special-purpose pencil is used for marking multiple-choice answer sheets and similar purposes.  A scanner detects the mark locations optically.  Nowadays, any number 2 or HB pencil usually suffices, but scanners were less sensitive in the past and special lead formulations were required.  These pencils are referred to by terms such as Test Scoring, Mark Sensing, Electrographic, Machine Scoring, and OMR (Optical Mark Recognition).

Many are black, suggestive of their dark marks:

  2. Friend, I used to love writing and Drawing with the Wallace 400 Machine Scoring Pencils. Do they still make them? If not, what would be the closest substitute?
