Patent number: 8155578Abstract: Methods and systems for generating and processing an assessment examination answer sheet are disclosed. An answer sheet is formatted by question, column or section using a layout tool and includes calibration marks, and examinee and examination identifiers. The format is stored in a computer-readable form, such as an XML file. A conventional printer prints the answer sheet prior to a test administration. Upon completion, a scanned image of the answer sheet is produced using a conventional scanner. The calibration marks are used to determine relative positions of answer sheet elements and to determine light and dark answer values. The examinee and examination identifiers identify the examinee and the proper stored format. Automatic grading ensues. A graphical user interface (“GUI”) assists grading of the answer sheet. The GUI may use confidence level indicators to denote answer choices or questions for which the grading system cannot precisely determine the intended response.Type: GrantFiled: September 27, 2004Date of Patent: April 10, 2012Assignee: Educational Testing ServiceInventor: Preston Cody

Patent number: 5420407Abstract: To determine a read level threshold for discriminating those response bubbles on a scannable answer sheet intended to be marked from those response bubbles not intended to be marked, an adjustable read level threshold is dynamically determined based on the read levels of a designated pool of response bubbles. In an optical scanner the darkness (read level) of each response mark entered for a particular question is determined to make a profile. From this profile showing the various read levels present for the response marks, the system determines read level "gaps," i.e., read levels in the profile for which there are no marks present, and adjusts the threshold for discriminating intended marks based on the read level(s) comprising the gaps.Type: GrantFiled: September 17, 1993Date of Patent: May 30, 1995Assignee: National Computer Systems, Inc.Inventor: John N.

Patent number: 4259667Abstract: Described is a method for utilizing a unique hand-held probe or the like, in conjunction with a responsive apparatus, as the means to establish cooperative response evaluation between an intelligent being and an evaluatory system. The method involves the emplacement of a translucent document, such as ordinary bond paper, over a field of individual light sources laid out in some predefined pattern which effects correspondence between the sources and indicia which is usually included on the document obverse surface. The copulative probe is positioned, usually by the being's hand, so as to receive some part of the light rays which permeate the paper and to convert the energy into a pattern of electrical signals which tell-tale which particular light element in the field of sources has been selected. The light rays which diffuse through the document also act to provide visible energy which can be perceived by the being to help guide the probe placement for strongest signal response.Type: GrantFiled: May 21, 1979Date of Patent: March 31, 1981Inventor: Harold J.
