ABSTRACT:
A test scoring system and method of testing a plurality of individuals utilizes a hand-held answer recording unit for each individual including a user operable input device for receiving and storing user answers. A scoring processor is provided for receiving answer data from each answer recording unit and comparing the answers with an answer key in order to determine conforming answers. A data transfer unit is connected with the scoring processor to receive answer data from the answer recording unit and transfer the answer data transparently to the scoring processor. Each student is provided a hand-held answer recording unit, along with a test, which is typically in written format. The user scrolls through the answer locations in the hand-held answer recording unit and inputs in each location an answer to each question. When the test is completed, the answer recording unit is juxtaposed with the data transfer unit and the data transfer unit produces a single bit discharge signal that is transferred to the answer recording unit across a physically impervious boundary. The answer recording unit responds to the discharge signal by transferring in sequential order all of the answer data across the physically impervious boundary to the data transfer unit. The data transfer unit includes a decoding circuit that responds to only the leading edges of the answer data signal in order to accurately decode the signal and, thus, allow a faster rate of data transfer. The decoded answer data is transferred to the scoring processor.
