To find universities that don't require the GRE for their Animal Science programs, you should:
1. Check each university's website directly: Go to the website of the Animal Science department (or relevant department like Agriculture, Veterinary Science, etc.) of universities you're interested in. Look for their graduate admissions requirements page. The information on GRE requirements will usually be clearly stated.
2. Contact the program directly: If the website isn't clear, email the graduate program coordinator or admissions committee for the specific Animal Science program. They will have the most up-to-date and accurate information.
3. Use online graduate program search engines: While these may not explicitly filter for "no GRE required," you can use the search filters to narrow down your results by program and then check each program's website individually. Examples include Peterson's, US News & World Report, and individual university graduate program search tools.
Keep in mind that even if a university doesn't require the GRE, a strong academic record, letters of recommendation, and a compelling statement of purpose will still be crucial for admission.
