The Pre-Elementary Education Longitudinal Study (PEELS) followed almost 3,000 children with disabilities as they progressed through preschool and into their early elementary years. PEELS collected data on the preschool and early elementary school experiences of a nationally representative sample of children with disabilities and the outcomes they achieved. It focused on 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 to 2008.
