Heres something i found:

Legally Exempt Child Care Providers for children from only 1 or 2 families.
These providers are not required to be registered with the state but may choose to go through a simple authorization process. Going through this process enables the care giver to receive payment from the state child care subsidy program (for a qualifying child in their care). There are no training requirements for these providers

In my state if you are not licensed you can not accept state payments from families.
