The Department of Education (Department) published final regulations in the Federal Register on September 20, 2016 to amend the Impact Aid Program (IAP) regulations issued under title VII of the Elementary and Secondary Education Act of 1965, as amended by the Every Student Succeeds Act. The amendatory instructions at the end of the 2016 final rule inadvertently removed some definitions from these regulations. This document corrects the regulations by adding those definitions back into the Code of Federal Regulations (CFR).
