ANPRM Draft ICT Standards & Guidelines 508 Chapter 2: Scoping Requirements
11
508 CHAPTER 2: SCOPING REQUIREMENTS
E201 Application
E201.1 Scope. ICT that is procured, developed, maintained, or used by agencies shall
conform to these requirements.
Advisory E201.1 Scope. Section 508 of the Rehabilitation Act (29 U.S.C. 794d)
applies to federal departments and agencies, including the U.S. Postal Service.
The term “agency” is defined in Section E103 to include the United States Postal
Service and other federal agencies and departments as specified in 44 U.S.C. 3502.
That section of the U.S.C. defines agency to mean any executive department, military
department, Government corporation, Government controlled corporation, or other
establishment in the executive branch of the Government (including the Executive
Office of the President), or any independent regulatory agency, but does not include (a)
the General Accounting Office; (b) Federal Election Commission; (c) the governments of
the District of Columbia and of the territories and possessions of the United States, and
their various subdivisions; or (d) Government-owned contractor-operated facilities,
including laboratories engaged in national defense research and production activities.
E202 General Exceptions
E202.1 General. ICT shall be exempt from these requirements to the extent specified
by E202.
E202.2 National Security Systems. This document does not apply to ICT operated by
agencies as part of a national security system, as defined by 40 U.S.C. 11103(a).
Advisory E202.2 National Security Systems. The term National Security System
means any telecommunication, or information system operated by the United States
government, the function, operation, or use of which involves:
• Intelligence activities;
• Cryptologic activities related to national security;
• Command and control of military forces;
• Equipment that is an integral part of a weapon or weapons system; or
• Systems which are critical to the direct fulfillment of military or intelligence missions.
Systems that are critical to the direct fulfillment of military or intelligence missions do not
include systems that are used for routine administrative and business applications.
Examples of routine administrative and business applications are payroll, finance,
logistics, and personnel management applications. Routine administrative and
business applications are covered by this document.
E202.3 Federal Contracts. ICT acquired by a contractor incidental to a contract shall
not be required to conform to this document.
508 Chapter 2: Scoping Requirements ANPRM Draft ICT Standards & Guidelines
12
Advisory E202.3 Federal Contracts. ICT that is incidental to a contract includes
materials which are, themselves, not deliverables under the contract. For example, if a
contractor uses money from a contract to acquire a laptop which is used to help create
the deliverable for the project, the laptop itself is considered incidental to the contract
since it is not part of the deliverable.
E202.4 Functions Located in Maintenance or Monitoring Spaces. Where ICT
functions are operable only from spaces occupied solely by service personnel for
maintenance, repair, or occasional monitoring of equipment, such functions shall not be
required to conform to the provisions of this document.
Advisory E202.4 Functions Located in Maintenance or Monitoring Spaces. Where
a maintenance or monitoring space is occupied by persons other than service personnel
whose job is to maintain, repair or occasionally monitor the ICT, the ICT functions
located in that space must be accessible. A network operations center is an example of
a space only for maintenance or monitoring and which is occupied by persons other
than service personnel such as operations managers and programmers.
When controls or interfaces of ICT that is located in maintenance or monitoring spaces
are operated remotely, they can be located almost anywhere. Consequently, the
functions of ICT they control would not typically be eligible for the exception in E202.4.
E202.5 Undue Burden or Fundamental Alteration. Where an agency determines in
accordance with E202.5 that conformance with the provisions of this document would
impose an undue burden or would result in a fundamental alteration in the nature of the
ICT, conformance shall be required only to the extent that it does not impose an undue
burden or result in a fundamental alteration in the nature of the ICT.
Advisory E202.5 Undue Burden or Fundamental Alteration. A determination by an
agency that conformance to a particular provision would result in an undue burden or a
fundamental alteration in the nature of the ICT does not exempt the ICT in its entirety
from coverage under this document. The agency must conform to those provisions that
do not result in an undue burden or a fundamental alteration in the nature of the ICT.
E202.5.1 Basis for a Determination of Undue Burden. In determining whether
conformance to the provisions of this document would impose an undue burden on
the agency, the agency shall consider the extent to which conformance would
impose significant difficulty or expense considering the agency resources available
to the program or component for which the ICT is to be procured, developed,
maintained, or used.
E202.5.2 Required Documentation. The responsible agency official shall
document in writing the basis for determining that conformance with provisions of
this document constitute an undue burden on the agency or would result in a
fundamental alteration in the nature of the ICT. The documentation shall include an
explanation of why and to what extent compliance with applicable provisions would
create an undue burden or a fundamental alteration in the nature of the ICT.
ANPRM Draft ICT Standards & Guidelines 508 Chapter 2: Scoping Requirements
13
E202.5.3 Alternative Means. Where conformance to the provisions of this
document imposes an undue burden or a fundamental alteration in the nature of the
ICT, the agency shall provide individuals with disabilities access to and use of
information and data by an alternative means that meets identified needs.
E202.6 Best Meets. Where ICT conforming to one or more provisions of this document
is not commercially available, the agency shall procure the product that best meets the
provisions of this document consistent with the agency’s business needs.
Advisory E202.6 Best Meets. Examples of procurements that must conform to the
provisions of this document unless they are not commercially available include
commercial off the shelf products and products developed in response to federal
government procurements. However, this document does not require agencies to
procure ICT that does not meet their business needs.
E202.6.1 Required Documentation. The responsible agency official shall
document in writing the basis for determining that ICT that fully conforms to the
provisions of this document is not commercially available. The documentation shall
include an explanation of why and to what extent a product conforming to applicable
provisions of this document is not commercially available and why the product that
was procured best meets the provisions of this document consistent with the
agency’s business needs.
Advisory E202.6.1 Required Documentation. The Federal Acquisition Regulation
(FAR) sets forth the documentation requirements for a determination of commercial
non-availability by a federal agency.
E202.6.2 Alternative Means. Where ICT that fully conforms to the provisions of this
document is not commercially available, the agency shall provide individuals with
disabilities access to and use of information and data by an alternative means that
meets identified needs.
Advisory E202.6.2 Alternative Means. Nothing in this document obviates or limits
the requirements of Sections 501 and 504 of the Rehabilitation Act of 1973, as
amended. Some individuals may require accommodations even for ICT that fully
conforms to the provisions of this document.
E203 Access to Functionality
E203.1 General. Agencies shall provide individuals with disabilities access to all
functionality of ICT, either directly or by supporting the use of assistive technology, and
shall comply with E203. In providing access to all functionality of ICT, agencies shall
ensure the following:
1. That federal employees with disabilities have access to and use of information
and data that is comparable to the access and use by federal employees who are
not individuals with disabilities; and
2. That members of the public with disabilities who are seeking information or data
from a federal agency have access to and use of information and data that is
508 Chapter 2: Scoping Requirements ANPRM Draft ICT Standards & Guidelines
14
comparable to that provided to the members of the public who are not individuals
with disabilities.
E204 Functional Performance Criteria
E204.1 General. When agencies develop, procure, maintain, or use ICT, ICT shall
conform to functional performance criteria specified in Chapter 3.
E205 Electronic Content
E205.1 Official Agency Communications. Regardless of the medium or the method
of transmission and storage, electronic content that communicates official agency
business, as determined by the agency mission, to a federal employee or a member of
the public shall conform to Level A and Level AA Success Criteria and Conformance
Requirements specified for web pages in WCAG 2.0 (incorporated by reference in
Chapter 1) when the content of the communication includes one or more of the
following:
1. Content that is public facing;
2. Content that is broadly disseminated throughout an agency, including templates;
3. Letters adjudicating any cause which is within the jurisdiction of the agency;
4. Internal and external program and policy announcements;
5. Notices of benefits, program eligibility, and employment opportunities and
decisions;
6. Forms, questionnaires and surveys;
7. Emergency notifications;
8. Formal acknowledgements and receipts; or
9. Educational and training materials.
Advisory E205.1 Official Agency Communications. WCAG is written to be
technology neutral. While oriented towards web pages which are defined as being
delivered using HTTP, it is straightforward to apply the WCAG 2.0 Success Criteria and
Conformance Requirements to all electronic content.
EXCEPTIONS: 1. Electronic content of any of the above types of communications
stored solely for archival purposes or retained solely to preserve the exact image of
the original hard copy shall not be required to conform to the provisions of this
document.
2. Works in progress and drafts that are not public facing and that are intended for
limited internal distribution shall not be required to conform to the provisions of this
document.
ANPRM Draft ICT Standards & Guidelines 508 Chapter 2: Scoping Requirements

Advisory E205.1 Official Agency Communications Exceptions. Nothing in this
document, including the exceptions to E205.1, obviates or limits the requirements of
Sections 501 and 504 of the Rehabilitation Act of 1973, as amended. In order to
avoid discrimination on the basis of disability, an agency may be required to provide
reasonable accommodations for federal employees who are individuals with
disabilities, or to make reasonable modifications in policies, practices, or procedures
in order to avoid discrimination on the basis of disability.
E206 Hardware
E206.1 General. Where components of ICT are hardware and transmit information or
have a user interface, those components shall conform to the applicable provisions of
Chapter 4.
E207 Platforms and Applications
E207.1 General. Where components of ICT are platforms or applications and transmit
information or have a user interface, those components shall conform to E207 and the
applicable provisions of Chapter 5.
E207.2 WCAG Conformance. User interface components and content of platforms
and applications shall conform to Level A and Level AA Success Criteria and
Conformance Requirements specified for web pages in WCAG 2.0 (incorporated by
reference in Chapter 1).
Advisory E207.2 WCAG Conformance. WCAG is written to be technology neutral.
While oriented towards web pages which are defined as being delivered using HTTP, it
is straightforward to apply the WCAG 2.0 Success Criteria and Conformance
Requirements to user interface components and content of platforms and applications.
E208 Documentation and Support Services

and shall conform to 402.
Advisory 402.1 General. Self-service machines, information kiosks, set-top boxes,
and devices like printers, copiers, fax machines, and calculators have closed
functionality because their functionality is self-contained. Their design precludes the
user from adding peripherals or software to them.
ICT has closed functionality for many reasons. These reasons include design or policy.
ICT may have closed functionality in practice even though the manufacturer did not
design or develop ICT to be closed. Computers which are “locked down” to the extent
that end users cannot adjust settings are functionally closed.
402.2 Speech Enabled. ICT shall be speech enabled. Operating instructions and
orientation, visible transaction prompts, user input verification, error messages, and all
displayed information for full use shall be accessible to and independently usable by
individuals with vision impairments. Speech shall be delivered through a mechanism

504.1 General. Where an application is an authoring tool, the application shall conform
to 504 to the extent that information required for accessibility is supported by the
destination format.
Advisory 504.1 General. Authoring tools are applications that are used to create and
edit documents or electronic content.
One example of an authoring tool is a web application that allows users to create new
web pages. Another example of an authoring tool is an application for editing video.
Authoring tools can also be used to create and publish content for use with
telecommunications products or services. One example of a telecommunications
authoring tool is an interactive voice response system (IVR) that includes software for
the creation of content used to populate menu choices. These requirements for
authoring tools enable this content to be accessible.
504.2 Content Creation or Editing. Authoring tools shall provide a mode of operation
to create or edit content that conforms to all Level A and Level AA Success Criteria and
all Conformance Requirements in WCAG 2.0 (incorporated by reference in Chapter 1)
for all features and formats supported by the authoring tool. Authoring tools shall retain
the option to override information required for accessibility.
Chapter 5: Platforms and Applications ANPRM Draft ICT Standards & Guidelines
40
Advisory 504.2 Content Creation or Editing. Content includes information and
sensory experience communicated to the user and encoding that defines the structure,
presentation, and interactions associated with those elements. Examples of content are
text, images, sounds, videos, controls, and animations.
Content includes materials derived from programmatic sources.
Examples of content formats are word processing files, presentation files, spreadsheet
files, text files, PDFs, and HTML files.
Authoring tools which remove information required for accessibility do not conform to
this provision. For example, if a video editing tool is used to edit a captioned movie, the
tool must not remove the captioning.
Authoring tools which automatically provide information required for accessibility can
make mistakes. As with automated spelling and grammar checking, it is important for
authors to retain control of the process with authoring tools.
EXCEPTION: Authoring tools shall not be required to conform to 504.2 when used to
directly edit plain text source code.
Advisory 504.2 Exception. Examples of authoring tools that are only plain text
editors include Emacs and Windows Notepad.
504.2.1 Preservation of Accessibility Information in Format Conversion. When
converting from one format to another or saving content in multiple formats,
authoring tools shall preserve the information required for accessibility to the extent
that the information is supported by the destination format.
Advisory 504.2.1 Preservation of Accessibility Information in Format
Conversion. One example of preservation of accessibility information in format
conversion is exporting HTML from a word processor where alternative text
associated with embedded images follows the native word processing format to the
HTML source code.
When converting from one format to another, a best practice is for authors to have
control over how information required for accessibility is handled in the destination
format. This best practice allows the author to ensure consistent use of the
information required for accessibility in both formats.
504.3 Prompts. Authoring tools shall provide a mode of operation that prompts authors
to create content that conforms to all Level A and Level AA Success Criteria and all
Conformance Requirements in WCAG 2.0 (incorporated by reference in Chapter 1).
Authoring tools shall provide prompts during initial content creation or shall activate
prompts when the content is near completion.
Advisory 504.3 Prompts. Prompts do not need to be provided for every element in the
content. Intrusive or overused prompts can decrease usability. Examples of prompts
that are activated when the content is near completion are a check or a “wizard”.
ANPRM Draft ICT Standards & Guidelines Chapter 5: Platforms and Applications
41
504.4 Templates. At least one template for each template type provided within the
authoring tool shall conform to all Level A and Level AA Success Criteria and all
Conformance Requirements in WCAG 2.0 (incorporated by reference in Chapter 1).
Advisory 504.4 Templates. Not all authoring tools provide templates. Where
templates are provided, this provision requires that templates support accessibility.

CHAPTER 6: DOCUMENTATION AND SUPPORT
SERVICES
601 General
601.1 Scope. The technical requirements in Chapter 6 shall apply where required by
Chapter 2 or where referenced by a requirement in this document.
602 Documentation
602.1 General. Documentation that supports the use of ICT shall conform to 602.
Advisory 602.1 General. Examples of documentation that supports ICT are installation
guides, user guides, and manuals that describe the features of a product and how it is
used. Documentation may take the form of stand-alone documents or be integrated into
products as on-line or context-sensitive help.
602.2 Accessibility and Compatibility Features. Documentation shall list and explain
how to use the accessibility and compatibility features of the ICT that support the
technical requirements of this document. Documentation shall include accessibility
features that are built-in and accessibility features that provide compatibility with
assistive technology.
Advisory 602.2 Accessibility and Compatibility Features. One example of an
accessibility feature is the ability to access commands and navigate using the keyboard.
Voice recognition, screen readers, and alternative keyboards rely upon keyboard control
of features for accessible and efficient operation. Keyboard navigation includes support
for the following: cursor keys (up, down, left and right arrows), tab and shift-tab (to
cycle through fields), enter or spacebar (to select or activate), hot keys, macros, and
other keyboard acceleration mechanisms.
Where ICT components are designed to be part of an integrated system, this provision
requires that the documentation explains how to configure the system to support
accessibility. For example, the documentation for a DVD player and multimedia
projector is required to explain how to configure the DVD player and projector to support
the display of closed captions.
602.3 Materials. When ICT support services provide documentation, documentation
materials shall conform to 602.3.
602.3.1 WCAG Conformant. Documentation in electronic format shall conform to
all Level A and Level AA Success Criteria and all Conformance Requirements in
WCAG 2.0 (incorporated by reference in Chapter 1).

603 Support Services
603.1 General. ICT support services including, but not limited to, help desks, call
centers, technical support, and training services shall conform to 603.
603.2 Information on Accessibility and Compatibility Features. ICT support
services and training shall include information on the accessibility and compatibility
features required by 602.2 to be listed and explained in ICT documentation.
Advisory 603.2 Information on Accessibility and Compatibility Features. A best
practice is for ICT support services to provide training programs about the following
topics: accessibility requirements for individuals with disabilities; methods of
communication used by individuals with disabilities; assistive technology commonly
used with ICT products; designing for accessibility; solutions for accessibility and
compatibility of ICT with assistive technology; the use of people-first language; and
sensitivity training concerning disability issues.
603.2.1 Method of Delivery. Support services shall be provided directly to the user
or through a referral to a point of contact. Support services that are provided
through a referral shall include a contact method conforming to 603.3.
Advisory 603.2.1 Method of Delivery. The Federal Communications Commission
maintains a list of contact information for telecommunications service providers and
manufacturers of telecommunications products that can be useful when support
services are provided through a referral.
603.3 Effective Communication. ICT support services shall accommodate the
communication needs of individuals with disabilities.
Advisory 603.3 Effective Communication. To be effective, communication with
individuals with disabilities should include alternate methods of communication for both
in-person and remote communication. Examples of alternative methods are sign
language interpreters, assistive listening systems, TTYs, real time captioning, and
telecommunications relay services. Examples of telecommunication relay services are
TTY speech-to-speech and video relay.
A best practice is for help desk and other ICT support services to use a variety of
communication technologies. Examples of such communication technologies include
Internet posting (such as message boards and website blogs), cellular telephones, two
way radios, email, fax, postal mail, texting, and instant messaging.
603.3.1 Materials Provided. When support services provide documentation, the
documentation materials shall conform to 602.

That section of the U.S.C. defines agency to mean any executive department, military
department, Government corporation, Government controlled corporation, or other
establishment in the executive branch of the Government (including the Executive
Office of the President), or any independent regulatory agency, but does not include (a)
the General Accounting Office; (b) Federal Election Commission; (c) the governments of
the District of Columbia and of the territories and possessions of the United States, and
their various subdivisions; or (d) Government-owned contractor-operated facilities,
including laboratories engaged in national defense research and production activities.

Advisory E202.2 National Security Systems. The term National Security System
means any telecommunication, or information system operated by the United States
government, the function, operation, or use of which involves:
• Intelligence activities;
• Cryptologic activities related to national security;
• Command and control of military forces;
• Equipment that is an integral part of a weapon or weapons system; or
• Systems which are critical to the direct fulfillment of military or intelligence missions.
Systems that are critical to the direct fulfillment of military or intelligence missions do not
include systems that are used for routine administrative and business applications.
Examples of routine administrative and business applications are payroll, finance,
logistics, and personnel management applications. Routine administrative and
business applications are covered by this document.

508 Chapter 2: Scoping Requirements ANPRM Draft ICT Standards & Guidelines
12
Advisory E202.3 Federal Contracts. ICT that is incidental to a contract includes
materials which are, themselves, not deliverables under the contract. For example, if a
contractor uses money from a contract to acquire a laptop which is used to help create
the deliverable for the project, the laptop itself is considered incidental to the contract
since it is not part of the deliverable.
E202.4 Functions Located in Maintenance or Monitoring Spaces. Where ICT
functions are operable only from spaces occupied solely by service personnel for
maintenance, repair, or occasional monitoring of equipment, such functions shall not be
required to conform to the provisions of this document.
Advisory E202.4 Functions Located in Maintenance or Monitoring Spaces. Where
a maintenance or monitoring space is occupied by persons other than service personnel
whose job is to maintain, repair or occasionally monitor the ICT, the ICT functions
located in that space must be accessible. A network operations center is an example of
a space only for maintenance or monitoring and which is occupied by persons other
than service personnel such as operations managers and programmers.
When controls or interfaces of ICT that is located in maintenance or monitoring spaces
are operated remotely, they can be located almost anywhere. Consequently, the
functions of ICT they control would not typically be eligible for the exception in E202.4.
E202.5 Undue Burden or Fundamental Alteration. Where an agency determines in
accordance with E202.5 that conformance with the provisions of this document would
impose an undue burden or would result in a fundamental alteration in the nature of the
ICT, conformance shall be required only to the extent that it does not impose an undue
burden or result in a fundamental alteration in the nature of the ICT.
Advisory E202.5 Undue Burden or Fundamental Alteration. A determination by an
agency that conformance to a particular provision would result in an undue burden or a
fundamental alteration in the nature of the ICT does not exempt the ICT in its entirety
from coverage under this document. The agency must conform to those provisions that
do not result in an undue burden or a fundamental alteration in the nature of the ICT.
E202.5.1 Basis for a Determination of Undue Burden. In determining whether
conformance to the provisions of this document would impose an undue burden on
the agency, the agency shall consider the extent to which conformance would
impose significant difficulty or expense considering the agency resources available
to the program or component for which the ICT is to be procured, developed,
maintained, or used.
E202.5.2 Required Documentation. The responsible agency official shall
document in writing the basis for determining that conformance with provisions of
this document constitute an undue burden on the agency or would result in a
fundamental alteration in the nature of the ICT. The documentation shall include an
explanation of why and to what extent compliance with applicable provisions would
create an undue burden or a fundamental alteration in the nature of the ICT.

information and data by an alternative means that meets identified needs.
E202.6 Best Meets. Where ICT conforming to one or more provisions of this document
is not commercially available, the agency shall procure the product that best meets the
provisions of this document consistent with the agency’s business needs.
Advisory E202.6 Best Meets. Examples of procurements that must conform to the
provisions of this document unless they are not commercially available include
commercial off the shelf products and products developed in response to federal
government procurements. However, this document does not require agencies to
procure ICT that does not meet their business needs.
E202.6.1 Required Documentation. The responsible agency official shall
document in writing the basis for determining that ICT that fully conforms to the
provisions of this document is not commercially available. The documentation shall
include an explanation of why and to what extent a product conforming to applicable
provisions of this document is not commercially available and why the product that
was procured best meets the provisions of this document consistent with the
agency’s business needs.
Advisory E202.6.1 Required Documentation. The Federal Acquisition Regulation
(FAR) sets forth the documentation requirements for a determination of commercial
non-availability by a federal agency.
E202.6.2 Alternative Means. Where ICT that fully conforms to the provisions of this
document is not commercially available, the agency shall provide individuals with
disabilities access to and use of information and data by an alternative means that
