is an audio coding standard for lossy digital audio compression (reducing the amount of data while still retaining a good sound quality). It was designed to be the successor of the MP3 audio format. AAC format generally achieves better sound quality than MP3 while using a similar rate of processing.

A discipline devoted to understanding and improving human behavior by focusing on defined, observable behaviors of social significance and demonstrating a reliable relationship between the procedures employed and the resulting behavioral change.

An assessment tool used to gather information about what happens immediately before and after an interfering behavior occurs.

Existing as an idea but not having a physical existence

The method a person uses to control an activity.

An access utility is a software program that modifies a standard keyboard to simplify operation of the keyboard, replace the mouse, substitute visual cues for sound signals, or add sound cues to keystrokes. Many basic modifications can be made through software that already exists on your computer. Altering font size, color contrast, and adding or modifying audio alerts can all be done without purchasing additional software. "Sticky keys" are another very useful modification tool that can be made using existing software. Sticky keys allow an individual to type one key at a time, sequentially, and experience the same results as holding down multiple keys simultaneously. For example, instead of holding down CTRL-ALT-DELETE at the same time, the individual can select each key, one at a time.

Accessibility features are options that exist within products that allow a user to adjust the settings to their personal needs. Products may come with accessibility features that can adjust to the individual's visual, mobility, hearing, language, and learning needs. Accessibility features allow individuals with disabilities to use products that may not otherwise be useful. They also serve as a piece of assistive technology because adjustments are being made to help the individual.

Features available in an operating system that help a user with a disability to run and navigate programs and applications (e.g., a screen magnifier).

The U.S. Department of Justice and the U.S. Department of Education also defines it as: Accessible means “an individual with a disability can access the same information, engage in the same interactions, and otherwise participate in or benefit from the same services, programs, and activities as individuals without disabilities, in a manner that provides substantially equivalent timeliness, privacy, independence, and ease of use.”

The environment supports the independence of students with vision, hearing, motor, or cognitive disabilities and is designed to be usable and barrier-free to the widest range of student variability.

Under U.S. copyright law, an “accessible format” is “an alternative manner or form that gives an eligible person access to the work when the copy or phonorecord in the accessible format is used exclusively by the eligible person to permit him or her to have access as feasibly and comfortably as a person without such disability.”

An alternative presentation of the information provided in a material. Common types of accessible formats for text-based materials include braille, large print, audio, digital text, and tactile graphics. Videos can be made accessible with closed captioning, audio description, and synchronized American Sign Language (ASL). Audio can be made accessible with text transcripts.

Accessible instructional materials or AIM are materials that are designed or converted in a way that makes them usable across the widest range of student variability regardless of format (print, digital, graphic, audio, video). IDEA specifically focuses on accessible formats of print instructional materials. In relation to IDEA, the term AIM refers to print instructional materials that have been transformed into the specialized formats of braille, large print, audio, or digital text.

Accessible media producers (AMPs) use a variety of means to transform print materials into specialized formats such as braille, audio, digital text, or large print formats exclusively for use by blind or other persons with print disabilities. States may assign source files from the NIMAC to AMPs for conversation to student-ready specialized formats. States may also designate an AMP as an authorized user (AU) so that the AMP can download files directly from the NIMAC as an agent of the state. Major AMPs supported by the U.S. Department of Education and involved in NIMAS work include the American Printing House for the Blind (APH), Bookshare, and Learning Ally (formerly RFB&D).

To provide something needed or suited, to adapt.

An accommodation is an allowed adjustment or alteration that provides equal access to the curriculum for a student with a disability. It does not change what the student is expected to learn or master; rather, it ensures access. The objectives of the curriculum remain intact. Accommodations may vary in type, intensity, or degree but maintain the original learning objectives and instructional content.

To gain possession of; to learn or develop a skill.

A computer application currently in use. For example, a user may have a word processor, an Internet browser, and her email open at the same time, but the active application is the one the individual is currently using.

ADLs refer to the things we normally do in daily living, including any daily activity we perform for self-care such as feeding ourselves, bathing, toilieting, dressing, grooming, getting in and out of bed, work, homemaking, and leisure.

An activity matrix displays learning goals and strategies to be implemented during daily routines and activities. The activity matrix contains information about classroom schedule(s) as well as the goals and teaching strategies that are planned.

Learners are allowed to participate in a preferred activity after using the target skill correctly.

Capacity to adjust oneself to different conditions or environments

Calculators that include a variety of features and functions that make them valuable tools for persons with disabilities.

An alternative to a standard keyboard, whose features make it easier to use, such as larger, high-contrast, or programmable keys.

Steady support or attachment

After an individual reaches the age of majority (typically 18), services provided to them are considered adult services. These are governed and administered by different laws and agencies and are not generally considered to be an entitlement, but rather are made available based on need and resource availability.

Defined by the Office of Special Education Programs at the U.S. Department of Education, “accessible educational materials (AEM)” are “print- and technology-based educational materials, including printed and electronic textbooks and related core materials that are required by SEAs and LEAs for use by all students, produced or rendered in accessible media, written and published primarily for use in early learning programs, elementary, or secondary schools to support teaching and learning.” AEM can be digitally accessible from the beginning, such as accessible digital educational materials, or rendered in accessible formats.

The age of majority is the legal age established under state law at which an individual is no longer considered a minor and, therefore, has the right and responsibility to make the legal choices that adults make. In most states, the age of majority is 18. However, the parents/guardians of youth with certain levels and types of disability may apply to delay the transfer of decision-making authority.

A forceful action or procedure; hostile, injurious, or destructive behavior or outlook especially when caused by frustration.

Alternative and augmentative communication (AAC) systems that require something other than the person's body to implement (e.g., pictures for PECS, a voice output device, a communication notebook)

Another category of assistive technology, these self-help aids help people with disabilities eat, bathe, cook and dress. A "low tech" example would be a fingernail brush with two suction cups attached to the bottom that could stick onto a flat surface in the bathroom. Such an ADL would allow a child with limited mobility to clean her nails without having to grip the brush. There are also "high tech" ADLS, many of which contain computerized components such electronic feeding devices, video modeling apps, etc.

Accessible instructional materials, or AIM, are materials that are designed or converted in a way that makes them usable across the widest range of student variability regardless of format (print, digital, graphical, audio, video). IDEA (the Individuals with Disabilities Education Act) specifically focuses on accessible formats of print instructional materials. In relation to IDEA, the term AIM refers to print instructional materials that have been transformed into the specialized formats of Braille, large print, audio, or digital text.

An alternative access/input device allows individuals to control their computers using tools other than a standard keyboard or pointing device. Examples include alternative keyboards, electronic pointing devices, sip-and-puff systems, wands and sticks, joysticks, and trackballs.

Developed by an occupational therapist at the Centre for Literacy and Disability Studies (CLDS), an alternative pencil is defined as anything that provides a student with access to all 26 letters of the English alphabet. During each writing session, the teacher models use of the student's alternative pencil, the student writes, and the student reads back his writing - all with varying and appropriate levels of support. Writing with alternative pencils allows students with significant disabilities to develop beginning writing skills by supporting them to go through the same developmental writing phases as typically developing students. Alternative pencils also address a student's other developing abilities such as eye gaze or switch use. For example, the alphabet eye-gaze frame may be helpful for students who are learning to eye gaze. The print flip chart or onscreen keyboards may be helpful for students who are learning to use switches.

The American Academy of Pediatrics (AAP) is an American professional association of pediatricians.

The Americans With Disabilities Act of 1990 (ADA) prohibits employers from discriminating against people with disabilities and makes such discrimination a civil rights violation. Providers of public services, schools, public buildings, and public transportation services also must provide accessibility to people with disabilities. In 2024, DOJ published a final rule under Title II, specifying accessibility requirements for web content and mobile apps.

Accessible media producers (AMPs) produce specialized formats of instructional materials such as Braille, audio, digital text, or large print for use by blind or other persons with print disabilities. Accessible media producers are eligible to download files directly from the NIMAC as agents of authorized users. Major AMPs supported by the U.S. Department of Education and involved in NIMAS work include the American Printing House for the Blind (APH), Bookshare, and Learning Ally (formerly RFB&D).

A broad term used to describe technology that helps people with hearing loss, with or without hearing aids, to hear. ALDs amplify and in some cases bring the target sound (television, telephone, communication partner, etc.) directly to the ear. They are often used when background noise and distance cause difficulty hearing.

An AT device is defined under IDEA as “any item, piece of equipment, or product system, that is used to increase, maintain, or improve the functional capabilities of a child and specifically excludes a medical device that is surgically implanted or the replacement of such device” (e.g., a cochlear implant). AT devices are often viewed on a continuum of low-tech (e.g., a pencil grip), mid-tech (audio book), or high-tech (e.g., dynamic communication device).

The Assistive Technology Act is intended to improve the provision of assistive technology to individuals with disabilities through comprehensive statewide programs of technology-related assistance.

According to IDEA (§300.6 Assistive Technology Services), assistive technology assessment is a process during which information is gathered in order to make assistive technology/service decisions. This process is designed to identify appropriate AT devices and services. The most useful assessments are generally those conducted within an individual's "customary environment" rather than in an unfamiliar testing site.

A brief conversation that the IEP team must have for each student with a disability that answers the question: Could this student benefit from the use of assistive technology? Teams must take into account the student's current performance, preferences, and previous assistive technology interactions.

Identified in the IDEA 2004 as "Any item, piece of equipment or product system, whether acquired commercially off the shelf, modified, or customized, that is used to increase, maintain, or improve the functional capabilities of children with disabilities. The term does not include a medical device that is surgically implanted, or the replacement of such device". [Authority 20 U.S.C. 1401(1)]

2. Purchasing, leasing, or otherwise providing for the acquisition of assistive technology devices by children with disabilities;
3. Selecting, designing, fitting, customizing, adapting, applying, maintaining, repairing, or replacing assistive technology devices;
4. Coordinating and using other therapies, interventions, or services with assistive technology devices, such as those associated with existing education and rehabilitation plans and programs;
5. Training or technical assistance for a child with a disability or, if appropriate, that child's family; and
6. Training or technical assistance for professionals (including individuals providing education or rehabilitation services), employers, or other individuals who provide services to, employ, or are otherwise substantially involved in the major life functions of that child.

Social assimilation refers to instruction that facilitates skill development or fundamental changes in the child that allows the child to be more successful in social interactions. Examples of social assimilation include social skill intervention strategies that are child specific, such as video modeling, social narratives, and self-monitoring.

The working definition of a social skill autopsy is "the examination and analysis of a social error to determine the cause of the error, the amount of damage that occurred, and to learn about the causal factor (s) in order to prevent reoccurrence in the future." The basic principle is to assist the child in analyzing actual social errors that she has made and to discuss the behavioral options that the child could have utilized in order to have improved the situation.

During a functional vocational evaluation, a professional watches an individual as he/she performs a job or various tasks, gathering information and data to determine if the work is a good match for their interests and abilities. This type of assessment should record not only the ease or difficulty with which a person is able to complete particular tasks, but also affective information - whether the person appears relaxed and happy while doing the job or is unduly stressed and agitated during or after completing the tasks. A functional vocational evaluation might also include an individual's ability to get to and from a job and their ability to get along with co-workers. Information from a functional vocational evaluation is used to refine educational experiences, courses of study, and employment activities/strategies prior to the transition.

Each public school child who receives special education and related services must have an individualized education program (IEP). The IEP should be a truly individualized document and should include such information as present levels of functioning, future goals, and services to be provided. By law, the IEP process must consider the need for assistive technology.

The document is developed, reviewed, and revised in accordance with IDEA regulations. An IEP has specific requirements, such as mandatory team membership, an annual review, annual measurable student goals, participation in the state assessment, and participation in the general curriculum.

The U.S. special education law that ensures services for infants, toddlers, children, and youth with disabilities through age 21. IDEA governs services provided by states and public agencies.

The law was initially passed in 1975 as P.L. 94-142. That law, known as the Education for All Handicapped Children Act, or the EHA, guaranteed that eligible children and youth with disabilities would have a free and appropriate public education (FAPE) available to them, designed to meet their unique educational needs. P.L. 94-142 has been amended many times since passing in 1975, most recently in 2004.

For interval-based self-management systems, the period of time during which learners are required to self-monitor their behavior. At the end of this interval, learners should be able to accurately self-record whether or not they correctly demonstrated the target behavior for the entire length of the interval. For instance, a learner may record whether or not he is on task with his work every five minutes. Therefore, this learner must stay on task for a five-minute interval in order to accurately self-record that he/she was on-task. If this learner was off-task at any point during the five-minute interval, he/she should self-record that the target behavior was not correctly demonstrated. Initially, intervals are set low enough so that learners experience success easily.

A data collection process that is used to record the occurrence of a particular behavior at specific time intervals (e.g., every 15 seconds, every 30 seconds).

Divides the total amount of time or session into equal intervals of time, and reinforcement is provided after each interval if responding during the interval was equal to or below a criterion limit.

Reinforcement occurs following a specific length of time and the occurrence of an appropriate response.

System used to record high-frequency behaviors such as staying on task, staying seated, and conversing with peers. With this type of system, learners self-record their engagement or non-engagement in the target behavior (if it is a behavior that teachers/practitioners are trying to decrease) after a certain period of time (i.e., an interval). An interval can be seconds or minutes long; however, learners with ASD most often record their behavior after a certain number of minutes.
