In the mid-1990s, under the law I referred to before, the federal government agreed to pay money toward child welfare in each state that increased their adoptions. Each state had a baseline for the number of adoptions, and when they increased by a certain percentage, the federal government would give them a bonus in their child welfare budget. They had already started increasing, but that made them soar.
The federal government contributes some money towards the monthly subsidy given to kids in foster care. It used to be that they did not contribute to the adoption subsidies that states provided. They realized this was a disincentive for states to get kids adopted, because they were getting money from the federal government if they were in foster care, but once they got adopted, they got nothing.
That changed in the early 1980s. The federal government gave some money for some children, not every kid in care but those who came from poor families. Each state sets the age at which kids age out of foster care. But there has been recognition that at 18 many of these kids are not ready for independence. Most of them still need families. Some states have decided to allow kids who are still in school to remain in care. Some have decided to allow kids who are developmentally delayed to remain in care for another three years.
Many of them weren't getting money from the federal government to help with this cost. In recent years, the federal government has in some circumstances begun to provide some financial assistance to states to keep kids in care that aren't ready for independence at 18.
We're still far from saying that all kids can stay in care. In states that allow some children to remain, they often have to be in college or vocational training to stay in foster care for a few more years.
