Nothing specifically – we had a paper application (v brief application though – basically you'd check off what you needed the money for: lodging, travel, materials, other) and the finaid office did the rest. School said you needed to have filed for a FAFSA to be eligible for this money.
The subject of the CARES money was brought up by some astute peers at a town hall a few weeks ago. My school said they got between 50-100k from the govt that had to be distributed by the end of May, but due to the unprecedented nature of this situation, did not have a special pathway in place for allocating the money. It's apparently "use it or lose it" money from the govt, so they said to reach out to finaid if we needed anything. The application they drafted was pretty simple, but I had materials on hand to confirm I was paying double rent d/t being unable to leave a quarantine just in case they needed it to verify.
