The GRE (Graduate Record Examination) is required for admission to graduate programs in many countries around the world, especially in English-speaking countries where it is commonly used as part of the admissions process for master's and doctoral programs. Some of the main countries where the GRE is commonly required include:

1. United States: Many universities in the United States require GRE scores for admission to graduate programs, particularly for master's and doctoral degrees. This is because the GRE is seen as a standardized measure of a student's readiness for graduate-level academic work and is used by admissions committees to assess applicants' aptitude and potential for success in their chosen fields of study.

2. Canada: Similarly, many universities in Canada require GRE scores for admission to graduate programs, although the extent to which the GRE is required may vary depending on the institution and the specific program. Like in the United States, GRE scores are often used by Canadian universities as part of the admissions process to evaluate applicants' academic abilities and potential for success in graduate studies.

3. United Kingdom: While the GRE is not as commonly required for admission to graduate programs in the United Kingdom as it is in the United States and Canada, some universities may request GRE scores as part of the application process, particularly for certain programs or for international students. The GRE may be used by UK universities to assess the academic abilities of applicants who have completed their undergraduate studies in countries where the education system is different from that of the UK.

4. Australia: Similarly, some universities in Australia may require GRE scores for admission to graduate programs, particularly for international students or for specific programs where the GRE is considered relevant. Australian universities may use GRE scores as one of several factors in evaluating applicants' suitability for graduate studies.

Overall, the GRE is required in these countries as a standardized measure to help universities assess the academic abilities and potential of applicants for graduate programs. It provides admissions committees with a common metric for comparing applicants from diverse academic backgrounds and helps them make informed decisions about which students are best suited for their programs.
