Reporting & Assessment
Across our funding interest areas, we support program evaluations that assess the impact of our individual grants and long-term investments, and capture key insights and lessons learned. We also support the evaluation of national and local systems that relate to our grant programs.
Our evaluations, conducted by independent evaluators, are designed to offer insight into both our successes and failures and help us refine our current funding strategies and identify new opportunities moving forward. In addition to informing our grantmaking, our evaluations also are designed to support broader health policy and practice, by contributing to the evidence base about what works when it comes to improving the nation's health. As they are completed, we share our evaluation findings to foster learning that can help advance positive change nationwide.
Another form of evaluation is retrospective reports, which look back over an entire body of work—for example, two decades tackling tobacco addiction as a public health concern. Looking back helps us find better ways forward.
