aHealthMPowers developed the School Setting Physical Activity Survey, which was administered to teachers pre-intervention (August 2013) and post-intervention (May 2014), to quantify school-level physical activity. HealthMPowers is an organization that promotes healthy eating and physical activity in schools using evidence-based guidelines established by the Centers for Disease Control and Prevention.
