NOTE: This is the official document published in the Federal Register on April 9, 2007and which took effect on May 9, 2007.

The U.S. Department of Education has released final regulations under the No Child Left Behind Act (NCLB) and the Individuals with Disabilities Education Act (IDEA) providing additional flexibility to states to more appropriately measure the achievement of certain students with disabilities. These regulations allow states to develop modified academic achievement standards that are challenging for eligible students and measure a student's mastery of grade-level content, but are less difficult than grade-level achievement standards. The new regulations are part of an ongoing effort to ensure that all students, including those with disabilities, fully participate in a state's accountability system and are assessed in an appropriate and accurate manner.

Part C of IDEA: Early Intervention for Babies and Toddlers
Under IDEA Part C, infants and toddlers with disabilities (birth-3) and their families receive early intervention services. Early intervention services for infants and toddlers with disabilities (birth-3) have been a part of IDEA since 1986. This section of the law is commonly known as Part C of IDEA. New proposed regulations for Part C were issued May 9, 2007 by the Office of Special Education and Rehabilitative Services at the U.S. Department of Education. These regulations, when issued in their final form, will reflect the changes resulting from IDEA 2004 and provide guidance to States on how Part C is to be implemented.
