Final answer:
TANF, which stands for Temporary Assistance for Needy Families, replaced the Aid to Families with Dependent Children (AFDC) program in 1996 as a result of welfare reform.
Step-by-step explanation:
The program that TANF replaced was Aid to Families with Dependent Children (AFDC). The transition occurred when the Personal Responsibility and Work Opportunity Reconciliation Act, notably termed as the "welfare reform act," was signed into law in 1996. This act aimed to overhaul the welfare system by implementing TANF, which provided state-administered grants for welfare programs. The goal of TANF is to support families with children to achieve economic self-sufficiency through assistance that is time-limited, typically with a 5-year maximum duration for assistance.
