Abstract
Existing as an idea but not having a physical existence

Access
The method a person uses to control an activity.

Access Utility
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
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.

Accessibility Options
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).

Accessible
Capable of being reached, used, seen, understood, or appreciated.

Accessible Environments
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.

Accessible Format
A text format that can be read using screen-reading programs.

Accessible Instructional Materials (AIM)
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)
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).

Accommodate
To provide something needed or suited, to adapt.

Accommodations
Adjusting for differences; supplying a need or want; In education, "accommodations" provide equal access to learning, do not substantially change the instructional level or content, are based on individual strengths and needs and may vary in intensity or degree.

Acquisition

Adult Services
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.

AEM
Accessible educational materials, or AEM, are print- and technology-based educational materials, including printed and electronic textbooks and related core materials that are designed or enhanced in a way that makes them usable across the widest range of learner variability, regardless of format (e.g. print, digital, graphic, audio, video).

Age of Majority
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.

Aggression

Aids for Daily Living
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.

AIM
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.

Alternative Access/Input Device
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.

Alternative Pencil
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.

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.
