This report describes the results of a survey conducted with State IDEA Part B Section 619 Coordinators in 2018. Questions were designed in partnership across Section 619 Coordinators, OSEP and ECTA center staff to gather information about state systems and services provided under the Preschool Grants Program (Section 619 of Part B) of IDEA. The purpose of this summary is to provide a national picture of state administration and practices related to serving young children with disabilities in accordance with the IDEA Part B, Section 619 Program to inform and assist State 619 Coordinators and their state and local partners in enhancing the quality of services for preschool children with disabilities and their families, as well as informing national efforts to support preschool special education programs.
