Hi, I hope that a former (and recent) study abroad student who went to the Philippines will answer your question with specifics. In the meantime, here are some resources to help you compile this information yourself...

StudyAbroad.com has a directory of schools and programs in the Philippines: http://www.studyabroad.com/philippines.html
