1. In a computerized test processing workflow system configured for analyzing electronic images of test question responses provided by a test taker, the system comprising a server subsystem having at least one server computer, a client subsystem having a plurality of client computers, and at least one of a plurality of types of optical imaging devices for electronically capturing the test question responses, wherein each type of optical imaging device is electronically identifiable, a method for increasing the volume of test question responses processed by embedding within each electronic image a individual digital identifier, the method comprising: a. receiving audit information, wherein the audit information comprises information pertaining to the optical imaging device, information pertaining to the type of test question response documents and process parameters; b. electronically generating at least one unique batch identifier at the server subsystem, wherein: 1. each unique batch identifier is based on the audit information, and 2. each unique batch identifier corresponds to a particular set of test question responses; c. optically imaging the particular set of test question responses; d. electronically embedding within each electronic image an individual digital identifier, wherein each individual digital identifier is based on: 1. the optical imaging device that was used to generate the electronic image; 2. the unique batch identifier; and 3. the sequence in which the test question responses were optically imaged; or 4. the coordinates of the image; e. selectively moving the electronic images of the particular set of test question responses through the individual workflow steps using the individual digital identifier; f. using the unique batch identifier to track the workflow progress of the particular set of electronic images; whereby, through the assignment of the individual digital identifier, the system distributes and tracks relatively small images grouped selectively by the unique batch identifier to be processed electronically or by appropriate human editors in a manner common for the particular set without the inefficiency of distributing the electronic images individually.
