To ensure compliance with federal reporting and program requirements for the fiscal year 2021, the Arizona Department of Education (ADE) is compiling data for student's special education data on October 1, 2020. Reports will be prepared using special education data that has been submitted by Arizona school districts, charter schools, and other public education agencies (PEAs) via their respective student information systems to ADE and has Passed Integrity in AzEDS accordingly. This system is a part of the October 1 Enrollment Data.
Vouchered students are normally reported by the district of residence (DOR) that is responsible for his or her education. In certain circumstances for students receiving services through an ASDB regional cooperative, a student may be attending a public school outside of the DOR.
