As data are released, associated instrumentation will become available on this page.

During the ECLS program’s 2020 field test data collections, the study tested the feasibility of including a national preschool round in the ECLS-K:2024. The 2020 field test data collection included only household surveys.

During the ECLS program's 2022 field test data collections, the ECLS will run a small-scale, trial run of the upcoming national study’s kindergarten and first-grade rounds. Children, with their parents’ or guardians’ consent, will answer engaging, age-appropriate math and reading-related questions during a one-on-one session with a trained ECLS team member. Parents/guardians of participating children will be asked to complete a survey about their family, their child’s experiences, and learning activities that the child participates in outside of school. Teachers will be asked to complete a brief survey about their professional background and teaching practices as well as surveys for each of their participating students about their skills and abilities. School administrators will be asked questions about their school and their own professional background.

The ECLS-K:2024 national study data collections will begin in fall 2023. The ECLS-K:2024 will collect data from:

children parents teachers school administrators.
