The Healthy Communities (formerly known as Steps) program evaluation page offers bestpractices for documenting program implementation, determining progress towards goals, and identifying areas for improvement. These communities address the burden of chronic diseases by implementing activities that help people to be more physically active, eat a healthy diet, stop using tobacco and better manage their diabetes and asthma. At the center of their evaluation strategy are the Core Performance Measures. Over the course of two years, stakeholders identified and agreed upon 18 measures and 44 related indicators; each reflects a critical component of Steps activities. The Core Performance Measures provide information about what and how results are achieved, reflect the best-possible science and practice-wisdom relevant to Steps communities, and take into account the practicalities of data collection at the community level.
