Final answer:
The information provided discusses welfare reform and the TANF program rather than the role or requirements for an EFMP coordinator. For correct information about the minimum service years for an EFMP coordinator, military or EFMP-specific regulations should be consulted.
Step-by-step explanation:
The question seems to be conflating two distinct topics: the role of an Exceptional Family Member Program (EFMP) coordinator and the details of welfare reform, particularly the Temporary Assistance for Needy Families (TANF) program established under President Bill Clinton. Regarding the EFMP coordinator, this role pertains to a military support program and has specific service requirements. However, the provided information does not mention the minimum duration for an EFMP coordinator's position. Instead, it references welfare reform policies, including the introduction of time limits on welfare benefits by the Contract with America in 1994, Clinton's adjustments, and states' flexibility in administration.
Hence, to answer the original question about the minimum years an appointed EFMP coordinator must serve to provide continuity, one would need to consult the specific regulations and policies of the military or the governing body of the EFMP. The information given does not contain the necessary details to answer this inquiry accurately.
