The Graduate Record Examinations or GRE in short is a standardized test and is an admission requirement for many graduate schools in the United States for other English-speaking countries and English-taught graduates and business programs worldwide. Developed and administered by Educational Testing Service (ETS) in 1949 the exam aims to measure verbal reasoning, quantitative reasoning, analytical writing and critical thinking skills that have been acquired over a long period of time and that are not related to any specific field of study. The GRE General Test is offered as a computer-based exam administered at prometric centers. In the graduate school admissions process, the level of emphasis that is placed upon GRE scores varies widely between schools and between departments within schools. The importance of a GRE score can range from being a mere admission formality to an important selection factor.
