I came to ask the same question that tk asked. At the very least, why didn’t they ask study abroad advisors? Study abroad advisors are familiar with who the other big players in the field are.
The reason the list is the way it is is because those are universities that created their own top study abroad programs OR that are recognized for having study abroad as a key part of the curriculum. NYU and Arcadia, for example, are two of the nation’s top offering universities of study abroad programs. Butler, Northeastern, and Pepperdine (which are further down on the list) are also universities that have created a wide range of study abroad programs.
However, those programs are by and large accessible by any college student - you don’t have to go to Butler, NYU, or Arcadia to engage the vast majority of their study abroad programs. My undergraduate college, for example, allowed students to attend any of those universities’ programs and get credit.
What I find more interesting are colleges who have study abroad as a key part of their undergrad experience or do something impressive with it.
For example, Goucher College doen’t actually create or administer most of the programs their students attend. If you look at the list on their website, they are the same study abroad programs everyone else is doing (USAC, SIT, IFE, some universities in the UK and in Japan that set up exchange agreements with tons of U.S. schools). The ones they do create are short courses over break periods that are taught by faculty of the college. BUT Goucher requires a study abroad experience for all of their students, and it’s a key part of their education and experience at the college.
And (not without a small bit of bias), I was hoping my alma mater might be on there and they are, at #32. Spelman’s in a similar boat to Goucher, where most of the programs they have are run and administered by other universities. What I think makes them stand out is that Spelman is also a college that has lots of students from lower-income families - 50% of Spelman students are Pell grant eligible - yet the college is still in the top 30 colleges in sending students to study abroad. One in five Spelman students studies abroad during her time there. But that’s because the college finds scholarships and financial aid to help students study abroad.
Agnes Scott’s place on the list is similar - because it’s such an important part of their curriculum and because so many of their students are low-income yet they still find the right programs and financial aid to encourage their students to go.
