Part B of IDEA governs how special education and related services are provided to school-aged children with disabilities.

Current as of October 2018

In Spanish | En español

Since the enactment of the original legislation in 1975, children and youth (ages 3-22) receive special education and related services under Part B of IDEA. Part B is so named because it’s the second part of the law itself. Its four parts are:

  • Part A – General Provisions
  • Part B – Assistance for Education of All Children with Disabilities
  • Part C – Infants and Toddlers with Disabilities
  • Part D – National Activities to Improve Education of Children with Disabilities

For school-aged children with disabilities (including preschoolers), Part B is the foundation upon which special education and related services rest.

How Part B is Organized

Here, in this area of our site, we’re concentrating on IDEA’s exact words.  Part B has eight (8) subparts. We provide you with direct access to these subparts and the verbatim language of the regulations.  You can read all the regulations in one place by downloading a copy of the law’s regulations. The regulations themselves start on page 46756.  All the pages before that are an analysis of comments received from the public and an explanation as to why certain changes to the regulations were made or not made.

You can also read IDEA’s subparts here online. Just use the links below to jump to the area of your interest. Because of the length of each subpart, we’ve divided them into separate webpages, as you can see by the guiding links below.
