What input device can be used for marking a multiple choice test?

Answer 1

When a multiple choice test is answered, a pencil mark is drawn in a small area (often looking like this [ A ] before completion) on an answer sheet to indicate the chosen response. The sheets are then fed into a machine which automatically reads the position of these marks, relays this information to a computer which interprets the data, processes it against a programmed data base and produces a response. In a test, the result is displayed as marks or a percentage. The system can also be used to compile reports or supply a fast way of entering numbers for a lottery draw.

The machine that reads the sheets is called an Optical Mark Reader (OMR for short). It works by light reflecting off the paper being picked up by a sensor. Where there are marks, less light is reflected and the relative position of the mark indicates the answer given. The position of the marks is calculated with the help of fixed marks on the paper which indicate the origin point. Some machines are programmed so that it doesn't matter which way round the paper is inserted, it still gives the desired data.

The system does rely on the use of specific forms: blank paper with lots of pencil dots is not an option!

Answer 2

A common input device used for marking a multiple-choice test is an optical mark recognition (OMR) scanner. OMR scanners detect marks made by pencils or pens on specially designed answer sheets. These marks are then converted into digital data for processing and scoring. OMR technology is widely used in educational institutions for efficient and accurate grading of multiple-choice exams.
