a) The average daily attendance was recorded at each site by research assistants during the week of data collection. The proportion of children who qualify for free or reduced price meals was collected via administrative records. Programs that were non-school based used data from the closest school as a proxy.
b) Child characteristics were reported by parents on consent forms.
