ABSTRACT:
An automatic grader device is provided including a scanner adapted to receive an answer key sheet and a plurality of student answer sheets and scan the sheets for storing the same electronically. Also included is a printer for printing copies of each of the student answer sheets scanned by the scanner and further printing additional characters thereon. An error detection mechanism serves to compare characters of each of the student answer sheets with those of the answer key sheet, deduct from a total score a worth of each error times a number of errors on each student answer sheet, print an "X" on the copy adjacent each error detected, and print a net score on the copy of the student answer sheet.
