This brief report updates data published in August 2010 from the most comprehensive, ongoing nationwide analysis of written wellness policies. It includes data from the 2006-07 through the 2010-11 school years, which were the first five years following the required implementation date for wellness policies. The major findings and trends presented identify areas where progress has been made in adopting and strengthening the written policies, as well as opportunities for improvement. New to this report are data relating to the reporting and assessment provisions required by the Healthy, Hunger-Free Kids Act. These data are especially relevant to USDA's (U.S. Department of Agriculture's) proposed rule for competitive foods and beverages, which was released in February 2013, and to the forthcoming proposed rule from USDA related to wellness policies. They also may help inform USDA's efforts to provide technical assistance to school districts regarding their wellness policies, which is required by the Healthy, Hunger-Free Kids Act. In addition, this report helps inform future policies for preventing childhood obesity and will be useful to advocates and state and local officials seeking to create a healthier school environment. This report highlights progress that has been made to implement, strengthen, and/or increase the comprehensiveness of the required wellness policy elements between school years 2006-07 and 2010-11. Consistent with prior reports, the data presented in this paper represent the percentage of students enrolled in public school districts nationwide. (Contains 4 figures and 4 tables.)
