This application is on a trust basis and no documents are required.
We trust that if you know that you need a sliding scale spot, that is why you're applying.
A true need of sliding scale is if the full rate of coaching ($120/ 60-minute session with 3-4 sessions per month or E-coaching at $130/month) means you have to give up needs (i.e. food, water, shelter, etc.) versus give up wants (spending on extra clothes, hobbies, Starbucks, etc.)
