Abstract: The systems and methods described herein provide techniques for grading a submission responsive to a learning prompt, such as that by an automated online braille grading system. The submission is parsed into strings. It is determined that a string does not match an answer string of answer data associated with the learning prompt. One or more errors are identified in the string by performing a character-by-character analysis of the first string. A report indicative of the identified errors in the string and a grading score is generated.
