The Secretary amends the regulations governing programs administered under Title I of the Elementary and Secondary Education Act of 1965 (ESEA), as amended by the No Child Left Behind Act of 2001 (NCLB) (referred to in these regulations as the Title I program) and the regulations governing programs under Part B of the Individuals with Disabilities Education Act (IDEA) (referred to in these regulations as the IDEA program). These regulations provide States with additional flexibility regarding State, local educational agency (LEA), and school accountability for the achievement of a small group of students with disabilities whose progress is such that, even after receiving appropriate instruction, including special education and related services designed to address the students' individual needs, the students' individualized education program (IEP) teams (IEP Teams) are reasonably certain that the students will not achieve grade-level proficiency within the year covered by the students' IEPs. These regulations are effective May 9, 2007.
