Abstract
A method of grading an essay using an automated essay scoring system is provided. The method comprises the steps of deriving a set of predetermined features from the essay, wherein the predetermined feature set comprises one or more features that are independent from the test prompt, scoring the feature set with a scoring equation, wherein a multiple regression analysis with graded essay data produces weights for the scoring equation, generating a raw score for the essay; and processing the raw score for the essay into a score category based on an adaptive cutoff algorithm. Also provided is a method of generating a model in which to grade essays, wherein the data used to generate the model is independent from the test prompt or essay topic.
