I know it is a lot of working applying to graduate school and once you submit everything you probably want to just sit back and await your admission decision. While I can understand this tendency, my highest recommendation is that each applicant dedicate time to researching ways to help pay for school.
I have provided some resources on the blog before and NASPAA also has a financial aid page that you might find beneficial. As I find out about more opportunities I will post them. Last spring I found out about a $22,500 scholarship, I posted it on the blog and an admitted SIPA student applied for and received the award. Stories like that one make me feel warm and fuzzy.
