Summary

Defines important words used in the law so people know what they mean. An "assistive technology device" is any tool or equipment that helps a child with a disability do more, but it does not include surgically implanted medical devices or their replacement. An "assistive technology service" is help a child needs to pick, get, or use those devices, including evaluation, buying or leasing, fitting, fixing, training for the child and family, and training for professionals. A "child with a disability" is a child with one of several listed conditions who needs special education and related services; for ages 3 through 9 (or a subset like ages 3–5) a State and local agency may also include a child with developmental delays as the State defines them. An "educational service agency" is a regional public agency that helps local school districts and runs special education programs. "Elementary school" and "secondary school" mean nonprofit day or residential schools that meet State law, with secondary not including education beyond grade 12. "Equipment" covers machinery and other items needed for a school to operate, like instructional tools and furniture. "Excess costs" are the extra costs above the average per-student spending in a local school district, calculated after deducting certain federal funds (under subchapter II, Title I Part A, and Title III Part A) and any State or local funds spent for those programs. "Free appropriate public education" means special education and related services provided at public expense, meeting State standards, covering preschool through secondary school, and following the child’s individualized education program (IEP). "Homeless children" means the same as "homeless children and youths" in another federal law. "Indian" and "Indian tribe" follow the usual meanings and include Alaska Native villages and regional village corporations. An "individualized education program (IEP)" is the written plan for each child with a disability developed under the law. "Individualized family service plan" and "infant or toddler with a disability" are defined elsewhere in the law. "Institution of higher education" means the usual federal definition and also includes colleges funded by the Secretary of the Interior under the Tribally Controlled Colleges and Universities Assistance Act of 1978. "Limited English proficient" means the same as "English learner" under the Elementary and Secondary Education Act. A "local educational agency" is a public school board or similar authority that runs public elementary or secondary schools and includes educational service agencies and certain Bureau of Indian Affairs schools for specific purposes. "Native language" for an English learner is the language normally used by the person or the child’s parents. "Nonprofit" schools or organizations are those run by nonprofit corporations where earnings do not go to private owners. "Outlying area" means the U.S. Virgin Islands, Guam, American Samoa, and the Commonwealth of the Northern Mariana Islands. "Parent" includes natural, adoptive, or foster parents (unless state law says a foster parent cannot serve), a guardian (but not the State for a child who is a ward), someone acting in place of a parent, or in some cases a surrogate parent. "Parent organization" and "parent training and information center" are defined elsewhere. "Related services" are supports like transportation, speech, psychological, physical and occupational therapy, counseling, medical services for diagnosis only, and other services needed to help a child benefit from special education; they do not include surgically implanted medical devices or their replacement. "Secretary" means the Secretary of Education. "Special education" means specially designed instruction at no cost to parents to meet a child’s unique needs, in many settings including classrooms, homes, hospitals, and physical education. "Specific learning disability" is a disorder in one or more basic psychological processes (examples include dyslexia and brain injury) that affects learning, and it does not include problems mainly caused by sensory, intellectual, emotional, or environmental factors. "State" means the 50 States, the District of Columbia, Puerto Rico, and the outlying areas. "State educational agency" is the State board or agency mainly responsible for supervising public schools. "Supplementary aids and services" are supports that help children with disabilities be educated with non-disabled children. "Transition services" are coordinated activities to help a student move from school to post-school life, based on the student’s needs and goals, and may include instruction, community experiences, and job-related preparation. "Universal design" is defined in another federal law. A "ward of the State" is a child who the State says is a foster child, a ward, or in the custody of a public child welfare agency, but it does not include a foster child who has a foster parent meeting the law’s definition of parent.
