Abstract: A method and system for assessing a student's reading ability is disclosed. An image-capturing device detects, from a worksheet comprising a position-identifying pattern, a first mark in a first region of the worksheet. The first mark is in a first indicator portion of the position-identifying pattern contained within a first indicator region that is associated with a first word. The image-capturing device detects a first note in a note region of the worksheet. Based on whether the first mark, the first note, or both indicates that the first word was read incorrectly or correctly, a processor determines a first reading assessment result for the first word and stores, in a memory, a digital document file comprising the first reading assessment result.

Abstract: An image is received that contains handwritten characters as answers to an inquiry. An automatic character recognition process is performed on the image to generate initially recognized characters from the handwritten characters. The initially recognized characters of an incorrect answer to a question of the inquiry are analyzed to automatically identify alternative recognized characters of the incorrect answer. Then, it can be determined whether one or more of the alternative recognized characters, when substituted in place of the initially recognized characters of the incorrect answer, change the incorrect answer to a correct answer to the question. If the alternative recognized characters substituted in place of the initially recognized characters in the correct answer exceed a minimum character recognition confidence value, the incorrect answer is changed to the correct answer to modify the initially scored answers to modified scored answers, and such are output.
