Pre-Elementary Education Longitudinal Study (PEELS)


PEELS followed almost 3,000 children with disabilities as they progressed through preschool and into their early elementary years. Data were collected on the preschool and early elementary school experiences of a nationally representative sample of children with disabilities and the outcomes they achieved and included children's preschool environments and experiences, their transition to kindergarten, their kindergarten and early elementary education experiences, and their academic and adaptive skills. The children were 3 to 5 years old at the start of the study in 2003 and were followed through 2008.


Over several years, information about the children, their families, and instructional/service programs were collected using family interviews, child assessments, and multiple questionnaires. The PEELS sample consists of approximately 1,000 children in each age cohort (3-, 4-, and 5-year olds) receiving special education services at the study onset. Direct assessments of children's academic skills and parent interviews were conducted. In addition, questionnaires were sent to participating children's teachers, school principals, directors of local education agencies, and state 619 (preschool special education) coordinators.

Training Videos

The PEELS data training modules are intended to be a resource to researchers who would like to use the PEELS dataset to conduct research addressing young children with disabilities. These modules provide opportunities for researchers to learn more about the background of the PEELS study, the study design and sampling, the assessments and instruments used to collect PEELS data, and how to access, manipulate, and analyze PEELS data.
