AGGREGATE LEVEL DATA ELEMENT COLLECTION INSTRUCTIONS
For the 2012 National ECEC Collection, an aggregate data collection methodology supports the collection of information on child and teacher data at the service provider level. For this collection, aggregate data can only be presented in terms of episodes of preschool program delivery. An episode is the count of the occurrence for a specific characteristic. For the National ECEC Collection, an episode refers to a preschool program provided to a child. When one child attends two different preschool programs, the child is attending two episodes of preschool.
