Tenn. Code Ann. § 71-3-702

During fiscal year 1989-1990, the department shall continue to operate Project RAP in Memphis as a model program, as it has since 1986. Beginning July 1, 1990, if and only if funds are specifically allocated in the general appropriations act for the purpose of expanding Project RAP, then the department shall geographically expand Project RAP into additional areas of the state in which there are significant concentrations of first time teen mothers, foster care teens, and other teens at high risk of pregnancy. In implementing such expansion, priority shall be given to establishing Project RAP in each of the state's three (3) grand divisions within those areas in which the project can exercise maximum impact both upon the state's pregnancy rate, among females seventeen (17) years of age and under, and upon taxpayer expenditures for temporary assistance for needy families (TANF), other types of public assistance, and medicaid.
