This study reports on the evaluation of the second North Carolina Healthful Living Institute (HLI), a statewide conference to promote comprehensive school health education. A comparison of year one and year two evaluation results is included. Based on a theoretical framework derived from the theory of diffusion of innovations within organizations, the impact of the HLI was assessed by studying characteristics of school districts sending representatives to the HLI and the composition of teams from each school district, and using pretest and posttest measures of participants' perceptions of the importance of health as a content area and participants' perceptions of the importance of the various components of comprehensive school health. Results indicate the effect of school health promotion conferences is linked to characteristics of school district teams, with the Institute needing to attract more varied teams, and teams from smaller, rural districts.
