The diagnostic category pervasive developmental disorders (PDD), as opposed to specific developmental disorders (SDD), was a group of disorders characterized by delays in the development of multiple basic functions including socialization and communication. It was defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM), and the International Classification of Diseases (ICD).
Special education is the practice of educating students in a way that accommodates their individual differences, disabilities, and special needs. This involves the individually planned and systematically monitored arrangement of teaching procedures, adapted equipment and materials, and accessible settings. These interventions are designed to help individuals with special needs achieve a higher level of personal self-sufficiency and success in school and in their community, which may not be available if the student were only given access to a typical classroom education.
Developmental disorders comprise a group of psychiatric conditions originating in childhood that involve serious impairment in different areas. There are several ways of using this term. The most narrow concept is used in the category "Specific Disorders of Psychological Development" in the ICD-10. These disorders comprise developmental language disorder, learning disorders, motor disorders, and autism spectrum disorders. In broader definitions ADHD is included, and the term used is neurodevelopmental disorders. Yet others include antisocial behavior and schizophrenia that begins in childhood and continues through life. However, these two latter conditions are not as stable as the other developmental disorders, and there is not the same evidence of a shared genetic liability.
Pervasive developmental disorder not otherwise specified (PDD-NOS) is a historic psychiatric diagnosis first defined in 1980 that has since been incorporated into autism spectrum disorder in the DSM-5 (2013).
An Individualized Education Program (IEP) is a legal document under United States law that is developed for each public school child in the U.S. who needs special education. It is created through a team of the child's parent(s) and district personnel who are knowledgeable about the child's needs. IEPs must be reviewed every year to keep track of the child's educational progress.
The following outline is provided as an overview of and topical guide to autism:
Developmental disability is a diverse group of chronic conditions, comprising mental or physical impairments that arise before adulthood. Developmental disabilities cause individuals living with them many difficulties in certain areas of life, especially in "language, mobility, learning, self-help, and independent living". Developmental disabilities can be detected early on and persist throughout an individual's lifespan. Developmental disability that affects all areas of a child's development is sometimes referred to as global developmental delay.
The University of North Carolina TEACCH Autism Program creates and disseminates community-based services, training programs, and research for individuals of all ages and skill levels with autism spectrum disorder (ASD), to enhance the quality of life for them and their families across the lifespan.
Autism therapies include a wide variety of therapies that help people with autism, or their families. Such methods of therapy seek to aid autistic people in dealing with difficulties and increase their functional independence.
Inclusion in education refers to all students being able to access and gain equal opportunities to education and learning. It arose in the context of special education with an individualized education program or 504 plan, and is built on the notion that it is more effective for students with special needs to have the said mixed experience for them to be more successful in social interactions leading to further success in life. The philosophy behind the implementation of the inclusion model does not prioritize, but still provides for the utilization of special classrooms and special schools for the education of students with disabilities. Inclusive education models are brought into force by educational administrators with the intention of moving away from seclusion models of special education to the fullest extent practical, the idea being that it is to the social benefit of general education students and special education students alike, with the more able students serving as peer models and those less able serving as motivation for general education students to learn empathy.
In the United States, the Individuals with Disabilities Education Act (IDEA) is a special education law that mandates regulation for students with disabilities to protect their rights as students and the rights of their parents. The IDEA requires that all students receive a Free and Appropriate Public Education (FAPE), and that these students should be educated in the least restrictive environment (LRE). To determine what an appropriate setting is for a student, an Individualized Education Plan (IEP) team will review the student's strengths, weaknesses, and needs, and consider the educational benefits from placement in any particular educational setting. By law the team is required to include the student's parent or guardian, a general education teacher, a special education teacher, a representative of the local education agency, someone to interpret evaluation results and, if appropriate, the student. It is the IEP team's responsibility to determine what environment is the LRE for any given student with disabilities, which varies between every student. The goal of an IEP is to create the LRE for that student to learn in. For some students, mainstream inclusion in a standard classroom may be an appropriate setting whereas other students may need to be in a special education classroom full time, but many students fall somewhere within this spectrum. Students may also require supplementary aids and services to achieve educational goals while being placed in a classroom with students without disabilities, these resources are provided as needed. The LRE for a student is less of a physical location, and more of a concept to ensure that the student is receiving the services that they need to be successful.
The assessment of basic language and learning skills is an educational tool used frequently with applied behavior analysis (ABA) to measure the basic linguistic and functional skills of an individual with developmental delays or disabilities.
The floortime or Developmental, Individual-differences, Relationship-based (DIR) model is a developmental model for assessing and understanding any child's strengths and weaknesses. This model was developed by Stanley Greenspan and first outlined in 1979 in his book Intelligence and Adaptation.
SINAI Schools is an organization based in the New York metropolitan area that provides education for children and young adults with special needs. SINAI is the only Jewish day school for children with special needs that has received accreditation from the Middle States Association of Colleges and Schools.
The term twice exceptional, often abbreviated as 2e, entered educators' lexicons in the mid-1990s and refers to gifted students who have some form of learning or developmental disability. These students are considered exceptional both because of their giftedness and because they are disabled or neurodivergent. Ronksley-Pavia (2015) presents a conceptual model of the co-occurrence of disability and giftedness.
Classic autism, also known as childhood autism, autistic disorder, (early) infantile autism, infantile psychosis, Kanner's autism,Kanner's syndrome, or (formerly) just autism, is a neurodevelopmental condition first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests. These symptoms first appear in early childhood and persist throughout life.
The Vanguard School is an approved private school in Malvern, Chester County, Pennsylvania, United States, approximately twenty-two miles northwest of Philadelphia on the campus of Valley Forge Educational Services.
The Ivy Street School is a school that offers multiple programs aimed at providing the skills and healing for neurodivergent youth to thrive. Through its educational, residential, and community-based programs, Ivy Street supports adolescents and young adults with disabilities by strengthening healing, deepening community, building skills and accelerating motivation for a successful adulthood.
HASA is a social benefit 501(c)(3) organization located in Baltimore, Maryland, that specializes in facilitating communication. Established in 1926, the organization provides special education services through Gateway School, audiology and speech-language services through its Clinical Services Department, and interpreting services for the deaf through its CIRS Interpreting Department.
Social (pragmatic) communication disorder (SPCD), also known as pragmatic language impairment (PLI), is a neurodevelopmental disorder characterized by significant difficulties in the social use of verbal and nonverbal communication. Individuals with SPCD struggle to effectively engage in social interactions, interpret social cues, and use language appropriately in social contexts. This disorder can have a profound impact on an individual's ability to establish and maintain relationships, navigate social situations, and participate in academic and professional settings. Although SPCD shares similarities with other communication disorders, such as autism spectrum disorder (ASD), it is recognized as a distinct diagnostic category with its own set of diagnostic criteria and features.
