1.0 What Is the GMAT ® Exam?
Th e Graduate Management Admission Test ® (GMAT ® ) is a standardized, three‐part test delivered in
English. Th e test was designed to help admissions officers evaluate how suitable individual applicants
are for their graduate business and management programs. It measures basic verbal, mathematical, and
analytical writing skills that a test‐taker has developed over a long period of time through education
Th e GMAT exam does not measure a person’s knowledge of specific fields of study. Graduate business
and management programs enroll people from many diff erent undergraduate and work backgrounds, so
rather than test your mastery of any particular subject area, the GMAT exam will assess your acquired
skills. Your GMAT score will give admissions officers a statistically reliable measure of how well you are
likely to perform academically in the core curriculum of a graduate business program.
Of course, there are many other qualifications that can help people succeed in business school and in
their careers—for instance, job experience, leadership ability, motivation, and interpersonal skills. Th e
GMAT exam does not gauge these qualities. Th at is why your GMAT score is intended to be used as
one standard admissions criterion among other, more subjective, criteria, such as admissions essays and
1.1 Why Take the GMAT ® Exam?
GMAT scores are used by admissions officers in over 6,000 graduate business and management
programs worldwide. Schools that require prospective students to submit GMAT scores in the
application process are generally interested in admitting
the best‐qualified applicants for their programs, which
means that you may find a more beneficial learning
environment at schools that require GMAT scores as part
of your application.
Because the GMAT exam gauges skills that are important
to successful study of business and management at the
graduate level, your scores will give you a good indication
of how prepared you are to succeed academically in a
graduate management program; how well you do on
the test may also help you choose the business schools
to which you apply. Furthermore, the percentile table
you receive with your scores will tell you how your
performance on the test compares to the performance
of other test‐takers, giving you one way to gauge your
competition for admission to business school.
– If I don’t score in the 90th
percentile, I won’t get into any
school I choose.
F – Very few people get very high
Fewer than 50 of the more than 200,000
people taking the GMAT exam each year
get a perfect score of 800. Thus, while you
may be exceptionally capable, the odds
are against your achieving a perfect score.
Also, the GMAT exam is just one piece of
your application packet. Admissions offi cers
use GMAT scores in conjunction with
undergraduate records, application essays,
interviews, letters of recommendation, and
other information when deciding whom to
accept into their programs.
