11. The method of claim 7 , wherein determining the third probability comprises determining historical assessment data associated with the student who completed the assessment; and determining the third probability based on at least a portion of the historical assessment data.
7. A method of determining one or more input characters based upon character recognition output of an education assessment system, the method comprising: receiving, by a processing device, a proposed character string generated using character recognition, wherein the proposed character string is associated with a plurality of handwritten characters of an assessment of a student, wherein the proposed character string comprises a first proposed character and a second proposed character; identifying one or more possible characters; determining, by the processing device, whether the first proposed character is correct, by, for one or more of the possible characters, determining an ultimate probability that the first proposed character is the possible character given the character string by: determining a first probability equal to a probability that if a true value of the first proposed character is the possible character that the first proposed character was identified, determining a second probability equal to a probability that if the true value of the first proposed character is the possible character that a following character is the second proposed character, determining a third probability equal to a probability that the student wrote the possible character, and determining a product of the first probability, the second probability and the third probability; and selecting the ultimate probability having the highest value.
