About the E-rater
What the E-rater Grades
E-rater is a distant cousin of the search engine robots that
scan content of web sites to determine how relevant they are
to search terms (such as that used by Alta Vista or the "concept
searching" Excite search engine). The E-rater will read
your essays and look for phrases that indicate competent reasoning.
E-rater uses a stored battery of hundreds graded essays for each
of the 280 essay questions. The E-rater has sample 1, 2, 3, 4,
5, and 6 score essays for each topic. The E-rater will evaluate
your essay in terms of the stored essays in the E-rater's database.
If the essay you wrote resembles the stored "6" essays
in the E-rater's database, you will get that score. If your essay
better resembles the "5's" in the E-rater's memory,
you will get a "5" from the E-rater.
is why it is so important to read the 20
sample essays we have. You will see how well written arguments
are structured and you will learn the proper style necessary
to impress both the E-rater and the human grader.
What the E-rater doesn't grade
E-rater cannot detect certain things, such as humor, spelling
errors or grammar. It analyzes structure through using transitional
phrases, paragraph changes, etc. It evaluates content through
comparing your score to that of other students. If you have a
brilliant argument that uses an unusual argument style, the E-rater
will not detect it.
E-rater does, however, detect spelling and grammar indirectly.
If your transition phrases and logical identifiers (e.g.- "therefore",
"for example") are not properly spelled the E-rater
will not detect them. Since the E-rater uses the presence of
such transitional phrases as an indicator of effective writing,
you are indirectly penalized if they are not spelled correctly.
