Purpose of the GRE Subject Tests
The GRE Subject Tests are designed to help graduate
school admission committees and fellowship sponsors
assess the qualifications of applicants in specific fields
of study. The tests also provide you with an assessment
of your own qualifications.
Scores on the tests are intended to indicate
knowledge of the subject matter emphasized in
many undergraduate programs as preparation for
graduate study. Because past achievement is usually
a good indicator of future performance, the scores
are helpful in predicting success in graduate study.
Because the tests are standardized, the test scores
permit comparison of students from different
institutions with different undergraduate programs.
For some Subject Tests, subscores are provided in
addition to the total score; these subscores indicate
the strengths and weaknesses of your preparation,
and they may help you plan future studies.
Development of the Subject Tests
Each new edition of a Subject Test is developed by a
committee of examiners composed of professors in the
subject who are on undergraduate and graduate faculties
in different types of institutions and in different
regions of the United States and Canada. In selecting
members for each committee, the GRE Program seeks
the advice of the appropriate professional associations
in the subject.
What Your Scores Mean
Your raw score–that is, the number of questions you
answered correctly minus one-fourth of the number
you answered incorrectly–is converted to the scaled
score that is reported. This conversion ensures that a
scaled score reported for any edition of a Subject Test
is comparable to the same scaled score earned on any
other edition of the same test. Thus, equal scaled
scores on a particular Subject Test indicate essentially
equal levels of performance regardless of the test
edition taken. Test scores should be compared only
with other scores on the same Subject Test.
