Since taking office, the President has emphasized the need to use evidence and rigorous evaluation in budget, management, and policy decisions to make government work effectively. This need has only grown in the current fiscal environment. Agencies should demonstrate the use of evidence throughout their Fiscal Year (FY) 2014 budget submissions. Budget submissions also should include a separate section on agencies' most innovative uses of evidence and evaluation, addressing some or all of the issues below. Many potential strategies have little immediate cost, and the Budget is more likely to fund requests that demonstrate a commitment to developing and using evidence. The Budget also will allocate limited resources for initiatives to expand the use of evidence, including but not limited to approaches outlined below. Agencies may include these initiatives in their submission at the guidance level or with proposed addbacks. In this memorandum, the following topics are presented: (1) Proposing new evaluations; (2) Using comparative cost-effectiveness data to allocate resources; (3) Infusing evidence into grant-making; (4) Using evidence to inform enforcement; and (5) Strengthening agency evaluation capacity. Support for Evidence-Based Initiatives is also presented.
