Category: Accessibility Architecture
History: Adopted on October 31, 2001.
The commission shall "[a]dopt minimum technical standards, guidelines, and architectures upon recommendation by the technical panel..." Neb. Rev. Stat. § 86-516(6).
The purpose of this document is to define and clarify policies, standards, and guidelines that will help agencies meet the needs of people with disabilities.
Neb. Rev. Stat. §73-205 required the Commission for the Blind and Visually Impaired, the Nebraska Information Technology Commission, and the Chief Information Officer to develop a technology access clause by January 1, 2001. TheTechnology Access Clause applies to all purchases of information technology. The clause includes the following provisions:
"The intent and purpose of these standards is to ensure that the needs of Nebraskans with disabilities are met through reasonable accommodation of the information technology products and services of the state. Future information technology products, systems, and services including data, voice, and video technologies, as well as information dissemination methods, will comply with the following standards to the greatest degree possible."
1. Effective, interactive control and use of the technology including, but not limited to, the operating system, applications programs, and format of the data presented must be readily achievable by individuals with disabilities. The intent is to make sure that all newly procured information technology equipment; software and services can be upgraded, replaced or augmented to accommodate individuals with disabilities.
2. Information technology made accessible for individuals with disabilities must be compatible with technology used by other individuals with whom the individual with a disability must interact.
3. Information technology made accessible for individuals with disabilities must be able to be integrated into networks used to share communications among employees, program participants, and the public.
4. Information technology made accessible for individuals with disabilities must have the capability of providing equivalent access to telecommunications or other interconnected network services used by the general population.
5. These provisions do not prohibit the purchase or use of an information technology product that does not meet these standards provided that:
a. There is no available means by which the product can be made accessible and there is no alternate product that is or can be made accessible; or
b. The information manipulated or presented by the product is inherently unalterable in nature (i.e., its meaning cannot be preserved if it is conveyed in an alternative manner).
c. The product is used in conjunction with an existing information technology system, and modifying the existing system to become accessible would create an undue burden.
d.The agency must be able to modify or replace the information technology product with one that will accommodate the needs of individuals with disabilities.
"When development, procurement, maintenance, or use of electronic and information technology does not meet these standards, individuals with disabilities will be provided with the information and data involved by an alternative means of access that allows the individual to use the information and data."
The primary objectives of accessibility standards and guidelines include:
1. Where feasible, people with disabilities can use the same information technology systems as people with out disabilities;
2. Early planning for accessibility will make it easier to provide reasonable accommodations when information technology systems are not accessible

Agency: shall mean any governmental entity, including state government,local government, or third party entities under contract to the agency.
Alternate formats: are usable by people with disabilities and may include, but are not limited to, Braille, ASCII text, large print, recorded audio, and electronic formats that comply with this part.
Alternate methods: are different means of providing information, including product documentation, to people with disabilities. Alternate methods may include, but are not limited to, voice, fax, relay service, TTY, Internet posting, captioning, text-to-speech synthesis, and audio description.
Assistive technology: includes any item, piece of equipment, or system, whether acquired commercially, modified, or cu stomized, th at is commonly used to incr ease, maintain, or improve functional capabilities of individuals with disabilities.
Electronic and information technology: includes information technology and any equipment or interconnected system or subsystem of equipment, that is used in the creation, conversion, or duplication of data or information. The term electronic and information technology includes, but is not limited to, telecommunications products (suchas telephones) information kiosks, and transaction machines, World Wide Websites, multimedia, and office equipment such as copies and fax machines. The term does not include any equipment that contains embedded information technology that is used as an integral part of the product, but the principal function of which is not the acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission, or reception of data or information. For example, HVAC (heating, ventilation, and air conditioning) equipment such as thermostats or temperature control devices, and medical equipment where information technology is integral to its operation, are not information technology.
Equivalent facilitation: provides that nothing in this part is intended to prevent the use of designs or technologies as alternatives to those prescribed in this part provided they result in substantially equivalent or greater access to and use of a product for people with disabilities.
Information technology: is any equipment or interconnected system or subsystem of equipment, that is used in the automatic acquisition, storage, manipulation, management, move ment, control, display, switching, interchange, transmission, or reception of data or information. The term information technology includes computers, ancillary equipment, software, firmware and similar procedures, services (including support services), and related resources.
Operable controls: are the component of a product that requires physical contact for normal operation. Operable controls include, but are not limited to, mechanically operated controls, input and outputtrays, card slots, keyboards, or keypads.
Product: is an electronic and information technology.
Self-contain ed, Closed Products: are products that generally have embedded software and are commonly designed in such a fashion that a user cannot easily attach or install assistive technology. These products include, but are not limited to, information kiosks and information transaction machines, copiers, printers, calculators, fax machines, and other similar types of products.
Telecommunications: are the transmission, between or among points specified by the user, of information of the user's choosing, without change in the form or content of the information as sent and received.
TTY: is an abbreviation for teletypewriter. Machinery or equipment that employs interactive text based communications through the transmission of coded signals across the telephone network. TTY's may include, for example, devices known as TDDs (telecommunication display devices) or telecommunication devices for deaf persons) or computers with special modems. TTYs are also called text telephones.
Undue burden: means significant difficulty or expense. In determining whether an action would result in an undue burden, an agency shall consider all agency resources available to the program or component for which the product is being developed, procured, maintained, or used.
These policies are intended to be sufficiently generic to apply to a wide range of governmental and educational agencies in the State of Nebraska. Each agency or operational entity must develop detailed procedures to implement broad policies and standards. Compliance with these accessibility policies and standards will be a requirement during consideration of funding for any projects requiring review by the NITC. Compliance may be used inaudit reviews or budget reviews.
The Governing board or chief administrative officer of each organization must develop internal compliance and enforcement policies as part of its information accessibility efforts. Such policies should be reasonable and effective. The NITC intends to incorporate adherence to accessibility policies as part of its evaluation and prioritization of funding requests. The NITC recommends that the Governor and Legislature give due consideration to requests for accessibility improvements during the budget process.
An effective program for accessibility involves cooperation of many different entities. Major participants and their responsibilities include:
The NITC provides strategic direction for state agencies and educational institutions in the area of information technology. The NITC also has statutory responsibility to adopt minimum technical standards and guidelines for acceptable and cost-effective use of information technology. Implicit in these requirements is the responsibility to promote adequate accessibility for information systems through adoption of policies, standards, and guidelines.
The NITC Technical Panel, with advice from the Accessibility Work Group, has responsibility for recommending accessibility policies and guidelines and making available best practices to operational entities.
The Nebraska Assistive Technology Partnership provides training, loan devices and support for accommodations in compliance with Section 508 and the Technology Access Clause. Training and support is available to governmental agencies, schools, businesses, and non-profit organizations.
The Accommodation Resource Center (ARC) provides training, loan devices and support for accommodation using assistive technology in both the education and employment environment. The ARC website
The Federal Information Technology Accessibility Initiative (FITA) is an interagency effort, coordinated by the General Services Administration, to offer technical assistance and to provide an information means of cooperation and sharing of information on implementation of Section 508. Questions about 508 standards can be sent to email@example.com.
The Web Accessibility Initiative has created guidelines, which are grouped by priority and are very similar to the final Section 508 rules. The guidelines can be found at W3.
The highest authority within an agency or institution is responsible for accessibility of information resources that are consistent with this policy. The authority may delegate this responsibility but delegation does not remove the accountability.
Technical staff must be aware of the opportunities and responsibility to meet the goals of accessibility of information systems.
