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.
