The Graduate Management Admission Test is a computer adaptive standardized test in mathematics and the English language for measuring aptitude to succeed academically in graduate business studies. The GMAT is only available as a Computer-Adaptive Test (CAT). The CAT test gets harder or easier in response to your performance. The second and third readers are humans, who evaluate the quality of the examinee’s ideas and his or her ability to organize, develop, and express ideas with relevant support. While mastery of the conventions of written English factor into scoring, minor errors are expected, and evaluators are trained to be sensitive to examinees whose first language is not English.
