The study’s first restricted-use and public-use data file releases are anticipated in 2024. The first files will contain data from the preschool and kindergarten rounds.
National study data collections will be informed by a series of field tests.
In 2020, the ECLS-K:2023 will test the operational procedures of the planned national spring 2022 preschool round in the preschool field test. A sample of schools educating students of kindergarten age will be selected. Within sampled school catchment areas, address-based sampling (ABS) will be used to select a sample of residential addresses to screen for the presence of young children in the household. Approximately 28,000 households will be screened to identify children who plan to attend kindergarten (or a kindergarten equivalent) the following fall. Multimode methods will be used for data collection, specifically mailings that will direct respondents to web screeners and, for those households with children of preschool age, parent surveys. Screeners and parent surveys will be available in paper format for households that do not complete them online. Both the online and paper instruments will be available in English and Spanish. It is expected that approximately 300 parents will complete the full parent survey.
In fall of 2021, the kindergarten and first-grade instruments will be tested in the K-1 FT. Fifty schools will be sampled from five geographic sites. Within each geographic area, the FT samples will represent different urbanicity levels and will include public and private schools. In each of the 50 sampled FT schools, 24 students will be selected from kindergarten classrooms and 24 students will be selected from first-grade classrooms. In addition, 12 second-grade students may be sampled from each school if the school offers that grade level. This sample of 1,200 kindergartners, 1,200 first-grade students, and 600 second-grade students will be used to develop assessments for the kindergarten and first-grade data collections. In addition, in each FT school, two kindergarten and two first-grade teachers will be recruited, yielding a sample of 200 teachers in 50 schools that will be used to examine the teacher questionnaire items. School administrators (one per school, for 50 school administrators) and special education teachers (estimated to be more than one per school, for about 60 teachers) will also be included in the field test. In addition, parents of the sampled children will be asked to complete the web survey to examine the parent items for the kindergarten and first-grade rounds.
In fall of 2024, the third- and fifth-grade instruments will be tested in the 3-5 FT. The same 50 sampled field test schools that participated in the K-1 FT will be recruited for the 3-5 FT, provided they have these grade levels; in addition, new schools will be sampled for the 3-5 FT to deal with attrition and schools dropping out due to not having the higher grade levels. Within each school, 24 students will be selected from third-grade classes and 24 students from fifth-grade classes. In addition, 12 fourth-grade students and 12 sixth-grade students will be sampled from each school, depending on the grade range of the school. Like the 3-5 FT, students’ teachers, school administrators, and parents will also participate to test the teacher, school administrator, and parent surveys, respectively, for the included study rounds.
