A system for evaluating a user-marked document including a user-marked response sheet having a response area and at least one image marker, a means for obtaining a digital image of the user-marked response sheet, a computer having programming to perform steps which include identifying three-dimensional position information of the at least one image marker in an obtained digital image, calculating position information of the response area in an obtained digital image using the three-dimensional position information of the at least one image marker, identifying position information of a user created mark within the response area using the calculated position information of the response area, and evaluating whether the position information of the user created mark corresponds with position information of a first predefined mark or a second predefined mark.
