Head Start employment verification when self-employed

My ffs was at head start when we first got him. He was in the all day program. To keep him in the all day program, I had to qualify (based on me working and our income). Since I work very part time, we chose to move him to a regular half day program. The half day program did not require any for my information to qualify. They moved him as soon as they had an opening and I did not have to pay for the all day program.
