How likely is it for an international student to secure graduate funding for a subject like Psychology?
My former UK Psychology department ran a neuroscience program. At the PhD level we had funding from outside grants, school funding, and university funding. Typically only the school and university funding could be used for international students. Technically, this means maybe 1/3 of the available funding could go to international students, but the school funding was almost always ear marked for special cases (i.e., a new faculty member or a supplement for getting a grant, or a reward for doing extra teaching). More typically only about 10% of our funded PhD students were international.
