This chartbook draws from data collected in the 2019 NSECE Center-based Provider Survey and 2019 NSECE Workforce Survey. In the NSECE, a center-based provider delivers CCEE services to children age five and under, not yet in kindergarten, at a single location. Center-based providers were identified from a national provider sampling frame built from state or national administrative lists such as state licensing lists, Head Start program records, or lists of public pre-K programs obtained from each state. These providers included regulated, licensed, and other private providers as well. Respondents to these nationally-representative surveys were directors or other instructional leaders of center-based CCEE providers to children age five and under, not yet in kindergarten. This chartbook uses data for approximately 6,900 centers. 2019 NSECE Workforce Survey respondents were sampled from the Center-Based Provider data, in which all staff members in a representative classroom had been enumerated. The representative classroom was selected at random from one of the age groups the center-based program reported serving, with one or two instructional staff members from that classroom sampled for the Workforce Survey. This chartbook focuses on center-based workforce members (teachers, assistants and aides) who were assigned to classrooms that served children age 5 and under, not yet in kindergarten. This chartbook uses data from almost 5,200 workers. (author abstract)
