GMAT Scoring
Total Score
The "Total Score", comprising the quantitative and verbal sections, is exclusive of the analytical writing assessment (AWA), and ranges from 200 to 800. About two-thirds of test takers score between 400 and 600. The score distribution resembles a bell curve with a standard deviation of approximately 100 points, meaning that the test is designed for 68% of examinees to score between 400 and 600, while the median score was originally designed to be near 500. The 2005/2006 mean score was 533.
The quantitative and verbal sections comprise a computer-adaptive test. The first question may be difficult. The next few questions in each section may be around the 500 level. If the examinee answers correctly, the next questions are harder. If the examinee answers incorrectly, the next questions are easier. The questions are pulled from a large pool of questions and delivered depending on the student's running score. These questions are regularly updated to prevent them from being compromised by students recording questions.
The final score is not based solely on the last question the examinee answers (i.e. - the level of difficulty of questions reached through the computer-adaptive presentation of questions). The algorithm used to build a score is more complicated than that. The examinee can make a silly mistake and answer incorrectly and the computer will recognize that item as an anomaly. If the examinee misses the first question his score will not necessarily fall in the bottom half of the range.
Also, questions left blank (that is, those not reached) hurt the examinee more than questions answered incorrectly. This is a major contrast to the SAT, which has a wrong-answer penalty. Each test section also includes several experimental questions, which do not count toward the examinee's score, but are included to judge the appropriateness of the item for future administrations.
Verbal and Quantitative Section scores range from 0 to 60. Analytical Writing Assessment scores range from 0 to 6 and represent the average of the ratings from the two GMAT essays. Because the essays are scored so differently from the verbal and Quantitative sections, essay scores are not included in the total score.
Required Scores
Most schools do not publish a minimum acceptable score or detailed statistics about the scores achieved by applicants. However, schools do generally publish the average and median score of their latest intake, which can be used as a guide.
At nearly all of the top business schools that are commonly listed in popular magazines and ranking services, the scores will average in the upper 600s or low 700s. The Wharton School of the University of Pennsylvania, commonly regarded as one of the top business schools in the U.S., reports an average score of 715; Harvard Business School, another top tier U.S. business school, reports a 2006 average of 707. Northwestern University's Kellogg School of Management reports an average GMAT of 700, with approximately 75 percent of enrolled students scoring between 650 and 740. At the Indian School of Business the class of 2009 reports an average score of 714, a median of 720 and with a staggering 77% of students enrolled scoring 700 and above. INSEAD, one of Europe's leading business schools with a highly multinational student body, reports a 2005 average of 705.
The Triple Nine Society uses the GMAT for one of their admissions test. A score of at least 750 is required to join the Triple Nine Society.
It may be possible to overcome a low test score with impressive real world accomplishments, good undergraduate performance, outstanding references and/or connections, particularly strong application essays, or coming from an underrepresented group.
