Once you know what kind of program you are looking for, it is time to research the various potential universities. Find out which colleges offer courses that match your needs and see if you can find out how these are taught, and by whom. Not all colleges are the same: some schools only offer programs at a Master’s level, while others focus on a select amount of PhD programs. Other, larger schools might have a larger amount of Master’s and PhD programs available. Remember that all American schools are free to use their own admission standards. It is possible that one of the schools you are interested in uses a completely different set of standards than another, similar university.
Make sure you research which universities are highly rated in the fields that you want to study. What kinds of programs do they offer, what are the costs, and do they offer financial support?
