Evaluation Projects

We conduct formative, process, and outcome evaluations for SNAP-Ed across South Carolina. We ask questions to inform program expansion, capacity building, and sustainability, as well as to identify promising practices and learn from challenges encountered. Our methods include both qualitative and quantitative approaches. Much of our evaluation follows or is inspired by the national SNAP-Ed Evaluation Framework. Each year we work with the state’s SNAP-Ed agencies to collect data for priority indicators to show program outcomes state-wide. These include:

  • MT1 – Healthy Eating Behavioral Changes
  • MT2 – Resource Management Behavioral Changes
  • MT3 – Physical Activity and Reduced Sedentary Behavioral Changes
  • ST7 – Organizational Partnerships
  • MT5 – Nutrition Supports 
  • MT6 – Physical Activity and Reduced Sedentary Behavior Supports 
  • ST8 – Multi-Sector Partnerships and Planning

We are also members of the Association of SNAP-Ed Nutrition Education Administrators (ASNNA) and their Evaluation Committee where we learn from and contribute to national SNAP-Ed evaluation projects.
