In the context of technology, accessibility most commonly refers to providing access for all people to web environments, including people with disabilities. Designing sites for the way that screen readers, text browsers, and other adaptive technologies interact with the web; choosing contrasting colors for readability; and providing alternative text tags for graphics are examples of making websites more accessible.
Footnote 9 of the RFP that established the National Center for Accessible Education Materials for Learning states: As used in this priority, ''accessibility standards'' means current or revised electronic and information technology accessibility standards (EITAS) developed and implemented under the authority of Section 508 of the Rehabilitation Act (29 U.S.C. 794d(2)(A)) as well as interstate and international communication access guidelines authorized under the Telecommunication Act Accessibility Guidelines (47 U.S.C. 255). The use of designs or technologies as alternatives to the EITAS is permitted provided they result in substantially equivalent or greater access to and use of a product for individuals with disabilities (36 CFR part 1194.5). The annual Section 508 Report to the President and Congress indicated the most common accessibility standards used by recipients of Federal financial assistance are Section 508 EITAS and the Web Content Accessibility Guidelines.
The term “accessible” is defined by the Office of Civil Rights, US Office of Education as when a person with a disability is afforded the opportunity to acquire the same information, engage in the same interactions, and enjoy the same services as a person without a disability in an equally effective and equally integrated manner, with substantially equivalent ease of use (Office of Civil Rights Compliance Review No.11-11-6002).
Accessible Educational Materials (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 converted in a way that makes them usable across the widest range of individual variability regardless of format (print, digital, graphic, audio, video).
Accessible Instructional Materials (AIM)
Accessible instructional materials, or AIM, refers to print-based educational materials that are converted into specialized formats (e.g., braille, large print, audio and digital text). As IDEA (the Individuals with Disabilities Education Act) specifically focuses on the provision of accessible formats of print instructional materials, the term AIM is used when referring to accessible materials related to the requirements of the IDEA statute and regulations.
Accessible Media Producers (AMPs)
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).
Accessible technology is technology that can be used by people with a wide range of abilities and disabilities. It incorporates the principles of universal design. Each user is able to interact with the technology in ways that work best for him or her. Accessible technology is either directly accessible (usable without assistive technology) or it is compatible with standard assistive technology. In the same way buildings with ramps and elevators are accessible, products that adhere to accessible design principles are usable by individuals with diverse abilities, needs and preferences. Definition adapted from AccessibleTech.org’s What is Accessible Electronic and Information Technology?
Alt Tag (alternative text)
An alt tag is a brief description of a single image designed to be read by a screenreader as an alternative to that image. Alt tags are approximately 4–10 words long and state the type of image and a brief summary of it; when possible the alt tag expresses the purpose of the image as well. Alt tag text does not interpret an image (i.e., smiling, not happy). A producer's note (prodnote) or long description (LD) is used to provide a full or comprehensive description of an image, chart, or graph.

In this context, a descriptive markup component delimiting the start or end (including its generic identifier and any attributes) of an element.
Targeted Technical Assistance (TTA)
TTA involves ongoing work with participating State Education Agencies (SEAs) and collaborating districts (LEAs) to assist with developing, improving and sustaining effective, efficient systems for the provision of specialized formats of print-based instructional materials to students with disabilities. All TTA work is aligned to the Critical Components of Quality Indicators for the Provision of AIM.
Footnote 7 of the RFP that established the National Center for Accessible Education Materials for Learning states: As used in this priority, ''technology'' means any equipment or interconnected system or subsystem for which the principal function is the creation, conversion, duplication, movement, control, display, switching, interchange, transmission, reception, or broadcast of data or information. It includes, but is not limited to, electronic content; telecommunication products; computers and ancillary equipment; software; information kiosks; transaction machines; videos; information technology services; and multifunction office machines that copy, scan, and fax documents.
Text Encoding Initiative (TEI)
Initially launched in 1987, the TEI is an international and interdisciplinary standard that helps libraries, museums, publishers, and individual scholars represent all kinds of literary and linguistic texts for online research and teaching using an encoding scheme that is maximally expressive and minimally obsolescent.

Text-to-speech or speech synthesis is the artificial production of human speech and is generally accomplished with special software and/or hardware. The quality of various speech generation engines can vary considerably. Some voices sound almost human while others sound more primitive and robotic. The robotic-sounding voices are considered desirable for achieving high rates of "reading" speed.
Uncontracted braille provides a character-by-character transcription of a source text and is sometimes considered best for teaching young children braille. For experienced readers, it does not provide the space saving (and therefore reading speed and efficiency) of contracted braille.
Universal Design for Learning (UDL)
Universal Design for Learning (UDL) is a framework of learning and teaching based on neuroanatomy and functional neuroimaging research techniques. UDL resists a one-size-fits-all approach to education and posits instead that teachers, educators, and instructional materials should effectively respond to individual differences inherent within a learning environment. Across learning goals, methods, materials, and assessments, Universal Design for Learning encourages offering—
- Multiple means of representation to give learners various ways of acquiring information and knowledge,
- Multiple means of expression to provide learners alternatives for demonstrating what they know, and
- Multiple means of engagement to tap into learners' interests, challenge them appropriately, and motivate them to learn.
Using UDL principles in a classroom removes obstacles to curriculum access and provides students with alternative methods to demonstrate what they know. It acknowledges that there is more than one way to learn and respects individual learning style differences.

Universally Designed Technologies
Products and services that are designed and delivered to be usable by people with the widest possible range of functional capabilities, which include products and services that are directly accessible (without requiring assistive technologies) and products and services that are interoperable with assistive technologies. (20 U.S.C. §1401(35)(IDEA); 20 U.S.C. §1003(23)(HEOA), both referencing the Assistive Technology Act of 1998, as amended, 29 U.S.C. §3002).
Validation is a term used to describe the process of reviewing an XML document for conformance to the rules of XML coding in general and to a specific technical standard in particular. This applies to EPUB, NIMAS, DAISY, and many more technical specifications.
Variability refers to the infinite range of combinations that make up learners. Variability is systematic and predictable, and curriculum can address variability effectively. From the perspective of UDL, three dimensions of systematic variability exist in every learning environment at every age: variability in the way people represent information, in the way they engage with material, and in the way they act upon material and show what they know.
Vector images are made up of lines, points, curves, shapes. Connections between and combinations of these elements are described with mathematics to delineate their relationships, enabling vector images to retain the same resolution and overall appearance regardless of size. Vector images are best for showing blocks and shapes of one color, precise lines, typography, etc.
Video is the recording, reproducing, or broadcasting of moving visual images. The recording of moving visual images made digitally or on videotape.
Video description or audio description refers to the inclusion of verbal or auditory description(s) of on-screen visuals intended to describe important visual details that are not contained or that cannot be understood from the main audio output alone. They are of particular value to individuals who are blind.

W3C (World Wide Web Consortium)
The W3C is an international consortium founded in 1994 to promote the evolution and ensure the interoperability of the World Wide Web. Working with the global community, the W3C produces specifications and reference software for free use around the world. The W3C established the Web Accessibility Initiative (WAI) in 1997. Changing the Web's underlying protocols, applications and, most importantly, the way content is developed, can significantly improve access to the Web by people with disabilities. The WAI has working groups developing comprehensive and unified sets of accessibility guidelines for content accessibility, browser accessibility, and authoring tool accessibility.
A particular type of website that allows collaborative authoring and editing of the content of that website.
XML (EXtensible Markup Language)
XML is a universal format for structured documents and data. It is a set of rules, guidelines, and conventions for designing text formats for data in a way that produces files that are easy to generate and read (by a computer), are unambiguous, and avoid common pitfalls such as lack of extensibility, lack of support for internationalization/localization, and platform-dependency. Like HTML, XML makes use of elements and attributes, but while HTML specifies what each means (and often how content will display in a browser), XML uses tags et al. only to delimit pieces of data and leaves the interpretation of that data completely to the application that reads it. The separation of content and its presentation is a primary advantage of XML.
