Local district wellness policies are designed to ensure that schools support student health by providing a healthy nutrition environment and opportunities for physical activity. The Kansas State Department of Education (KSDE) developed a 5-year initiative to strengthen wellness policies across their state by offering regional wellness workshops and providing coaches to work with individual districts. KSDE also developed the Wellness Impact Tool (WIT), a self-report measure districts use to document their practices at each school level related to Nutrition, Nutrition Promotion, Physical Activity, and Integrated School-Based Wellness. Kansas districts ( N = 286) completed the WIT annually over a 5-year period. The current study evaluates the KSDE wellness initiative by examining the changes in WIT scores over time and by school level, and testing whether greater engagement with wellness supports (i.e., workshops attended and coaching sessions received) predicts higher WIT scores. The findings indicate that district WIT scores increased over the 5-year initiative. Overall, high schools scored higher than elementary or middle schools on Nutrition items, and elementary schools scored higher than other school levels in the domains of Nutrition Promotion, Physical Activity, and Integrated School-Based Wellness. The number of wellness supports utilized by districts each year were significant predictors of subsequent WIT scores. The KSDE’s initiative to support Kansas school districts was associated with significant improvements in the quality of wellness practices across the state and provides a model for consideration by other states.
