CLASS Users

We want to hear about how you’re using CLASS data to enhance efforts to address childhood obesity and improve school PE and nutrition programs. In particular, we want to hear how researchers are using CLASS to evaluate school health policy’s impact on behavior and health outcomes; how state officials are monitoring their state’s efforts to improve PE and nutrition and compare their progress against that of other states; and how school systems are using the data to examine current trends in PE and nutrition policies and to stay up-to-date on current standards, requirements, and policies in their state.
