“(a) Evaluation of the impacts of TANF.—The Secretary shall conduct research on the effect of State programs funded under this part and any other State program funded with qualified State expenditures (as defined in section 409(a)(7)(B)(i)) on employment, self-sufficiency, child well-being, unmarried births, marriage, poverty, economic mobility, and other factors as determined by the Secretary.

“(b) Evaluation of grants To improve child well-Being by promoting healthy marriage and responsible fatherhood.—The Secretary shall conduct research to determine the effects of the grants made under section 403(a)(2) on child well-being, marriage, family stability, economic mobility, poverty, and other factors as determined by the Secretary.

“(c) Dissemination of information.—The Secretary shall, in consultation with States receiving funds provided under this part, develop methods of disseminating information on any research, evaluation, or study conducted under this section, including facilitating the sharing of information and best practices among States and localities.

“(d) State-Initiated evaluations.—A State shall be eligible to receive funding to evaluate the State program funded under this part or any other State program funded with qualified State expenditures (as defined in section 409(a)(7)(B)(i)) if—

“(1) the State submits to the Secretary a description of the proposed evaluation;

“(2) the Secretary determines that the design and approach of the proposed evaluation is rigorous and is likely to yield information that is credible and will be useful to other States; and

“(3) unless waived by the Secretary, the State contributes to the cost of the evaluation, from non-Federal sources, an amount equal to at least 25 percent of the cost of the proposed evaluation.

“(e) Census Bureau research.—

“(1) The Bureau of the Census shall implement or enhance household surveys of program participation, in consultation with the Secretary and the Bureau of Labor Statistics and make available to interested parties, to allow for the assessment of the outcomes of continued welfare reform on the economic and child well-being of low-income families with children, including those who received assistance or services from a State program funded under this part or any other State program funded with qualified State expenditures (as defined in section 409(a)(7)(B)(i)). The content of the surveys should include such information as may be necessary to examine the issues of unmarried childbearing, marriage, welfare dependency and compliance with work requirements, the beginning and ending of spells of assistance, work, earnings and employment stability, and the well-being of children.

“(2) To carry out the activities specified in paragraph (1), the Bureau of the Census, the Secretary, and the Bureau of Labor Statistics shall consider ways to improve the surveys and data derived from the surveys to—

“(A) address underreporting of the receipt of means-tested benefits and tax benefits for low-income individuals and families;

“(B) increase understanding of poverty spells and long-term poverty, including by facilitating the matching of information to better understand intergenerational poverty;

“(C) generate a better geographical understanding of poverty such as through State-based estimates and measures of neighborhood poverty;

“(D) increase understanding of the effects of means-tested benefits and tax benefits on the earnings of low-income families; and

“(E) improve how poverty and economic well-being are measured, including through the use of consumption measures.

“(f) Research and evaluation conducted under this section.—Research and evaluation conducted under this section designed to determine the effects of a program or policy (other than research conducted under subsection (e)) shall use experimental designs using random assignment or other reliable, evidence-based research methodologies that allow for the strongest possible causal inferences when random assignment is not feasible.

“(g) Development of what works clearinghouse of proven and promising approaches To move welfare recipients into work.—

“(1) IN GENERAL.—The Secretary, in consultation with the Secretary of Labor, shall develop a database (which shall be referred to as the ‘What Works Clearinghouse of Proven and Promising Projects to Move Welfare Recipients into Work’) of the projects that used a proven approach or a promising approach in moving welfare recipients into work, based on independent, rigorous evaluations of the projects. The database shall include a separate listing of projects that used a developmental approach in delivering services and a further separate listing of the projects with no or negative effects. The Secretary shall add to the What Works Clearinghouse of Proven and Promising Projects to Move Welfare Recipients into Work data about the projects that, based on an independent, well-conducted experimental evaluation of a program or project, using random assignment or other research methodologies that allow for the strongest possible causal inferences, have shown they are proven, promising, developmental, or ineffective approaches.

“(2) CRITERIA FOR EVIDENCE OF EFFECTIVENESS OF APPROACH.—The Secretary, in consultation with the Secretary of Labor and organizations with experience in evaluating research on the effectiveness of various approaches in delivering services to move welfare recipients into work, shall—

“(A) establish criteria for evidence of effectiveness; and

“(B) ensure that the process for establishing the criteria—

“(i) is transparent;

“(ii) is consistent across agencies;

“(iii) provides opportunity for public comment; and

“(iv) takes into account efforts of Federal agencies to identify and publicize effective interventions, including efforts at the Department of Health and Human Services, the Department of Education, and the Department of Justice.

“(3) DEFINITIONS.—In this subsection:

“(A) APPROACH.—The term ‘approach’ means a process, product, strategy, or practice that is—

“(i) research-based, based on the results of one or more empirical studies, and linked to program-determined outcomes; and

“(ii) evaluated using rigorous research designs.

“(B) PROVEN APPROACH.—The term ‘proven approach’ means an approach that—

“(i) meets the requirements of a promising approach; and

“(ii) has demonstrated significant positive outcomes at more than 1 site in terms of increasing work and earnings of participants, reducing poverty and dependence, or strengthening families.

“(C) PROMISING APPROACH.—The term ‘promising approach’ means an approach—

“(i) that meets the requirements of subparagraph (D)(i);

“(ii) that has been evaluated using well-designed and rigorous randomized controlled or quasi-experimental research designs;

“(iii) that has demonstrated significant positive outcomes at only 1 site in terms of increasing work and earnings of participants, reducing poverty and dependence, or strengthening families; and

“(iv) under which the benefits of the positive outcomes have exceeded the costs of achieving the outcomes.

“(D) DEVELOPMENTAL APPROACH.—The term ‘developmental approach’ means an approach that—

“(i) is research-based, grounded in relevant empirically based knowledge, and linked to program-determined outcomes;

“(ii) is evaluated using rigorous research designs; and

“(iii) has yet to demonstrate a significant positive outcome in terms of increasing work and earnings of participants in a cost-effective way.”.
