The IBM 805 Test Scoring Machine was an educational machine sold by IBM beginning in 1937. [1] The device scored answer sheets marked with special "mark sense" pencils. The machine was developed from a prototype developed by Reynold Johnson, a school teacher who later became an IBM engineer. That machine and its descendants have been in use ...
The IBM 1230 is an offline optical mark reader that can read and score 1,200 test answer sheets per hour. [5] It uses a wire matrix to printer to print the test results on the right margin of the answer sheet as the sheet is being processed. It can optionally send output to an IBM 534 Model 3 Card Punch.
The first mark sense scanner was the IBM 805 Test Scoring Machine; this read marks by sensing the electrical conductivity of graphite pencil lead using pairs of wire brushes that scanned the page. In the 1930s, Richard Warren at IBM experimented with optical mark sense systems for test scoring, as documented in US Patents 2,150,256 (filed in ...
IBM bought Johnson's invention and hired him as an engineer - the machine was sold as the IBM 805 Test Scoring Machine. The first large-scale use of the IBM 805 was by the American Council on Education's Cooperative Test Service in 1936; in 1947, the Cooperative Test Service became part of the Educational Testing Service. Johnson went on to ...
The test scoring machine was sold as the IBM 805 Test Scoring Machine beginning in 1937. One of Reynold's early assignments was to develop technology that allowed cards marked with pencil marks to be converted into punched cards. That allowed punched card data to be recorded by people using only a pencil.

Dr. Michael Somenek, a board-certified facial plastic surgeon at Somenek + Pittman MD (which has locations in Washington D.C. and N.Y.C.) that the upshot of using filler composed mostly of ...
As a result of the fast-growing use of ITBS tests, he developed the first practical optical mark recognition system as a replacement for the electrical mark sense IBM 805 Test Scoring Machine. Although many of his colleagues at the University of Iowa contributed to the invention, Lindquist is generally credited with this development and is the ...
