The GMAT
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. Business schools commonly use the test as one of many selection criteria for admission into graduate business administration programs (e.g. MBA, Master of Accountancy, etc.) principally in the United States, but also in other English-speaking countries.
