abstract="This report discusses a multisite program evaluation in elementary schools that incorporated playground observations to document student behavior. A number of challenges are discussed, some of which were consistent with observer reactivity effects long documented in the literature, while others we believe were unique to this particular setting and provide a cautionary tale for those collecting school-based observation data.<p />",
