If a state chooses to use federal welfare funds to contract with, or to provide vouchers redeemable by, any nongovernmental social-service provider, then the state must comply with the Charitable Choice requirement not to discriminate against faith-based providers. The provision applies when states enter into purchase-of-service contracts or voucher arrangements with independent-sector organizations under the new Temporary Assistance for Needy Families program (the replacement for AFDC). Charitable Choice ... applies to the Supplementary Security Income (SSI) program. 4
